1) Example of system configuration of the image formation

Fig.1 is a diagram that shows the overall configuration of the system 500 of forming image according to a variant implementation of the present invention. The system 500 of forming the image includes a terminal device 100 camera (IP camera) and many of the client terminals 200. The terminal device 100 of the camera and each is th of the client terminals 200 are connected through the computer network 300, such as the Internet. The server 400 connected to the network 300 and the server 400 is connected via a computer network 300 with a terminal device 100 of the camera and many of the client terminals 200.

The terminal device 100 camera is a camera that is installed indoors or outdoors, and the terminal device 100 cameras offered with block 102 of the camera which includes a lens optical system that forms an object image, and an imaging element that converts solar method, the formed image of the object. The terminal device 100 of the camera is additionally proposed unit 104, the image processing unit 106 transmit/receive unit 108, the control unit 110 settings and timer 112.

The client terminal 200 is, for example, a device such as a personal computer (PC). The client terminal 200 is equipped with a block 202, the transmitting/receiving unit 204, the control unit 206 of the input unit 208 of the display. It is necessary to take into account that each of the functional blocks of the terminal device 100 of the camera and the client terminal 200 shown in Fig.1, is formed by the hardware (integrated circuits) or an arithmetic processor such as a Central processing unit (CPU) and software (what TEP), which makes the arithmetic processor to function. In the latter case, the program may be stored in a memory provided in the terminal device 100 of the camera or in the client terminal 200, or the program may be stored on storage media such as external memory, which is inserted from the outside. The server 400 is equipped with advanced image processing features similar to the functions of the terminal device 100 of the camera, and the server 400 may record the image obtained by the terminal device 100 of the camera. The server 400 may also be provided with functions of the client terminal 200.

In addition, the functions of the server 400 can be combined with a terminal device 100 of the camera.

Fig.2 is a diagram that shows the processing performed by the system 500 of image formation. Here is an example of the terminal device 100 cameras installed in the conference hall. As shown in Fig.2, the block 102 of the camera terminal device 100, the camera captures a full image of a relatively wide range within the conference room.

Full image, for example, is transmitted to the client terminal 200 in the form of a data frame, but the present invention is not limited to this example. Live video can be transmitted to the client terminal 200, and each of the client terminals 200, the printer is receiving this straight video can extract video frames. The user can use the client terminal 200 to determine the desired range of the full image. For example, when the area A, shown in Fig.2, defined by the client terminal 200, the terminal device 100 camera encodes data direct recording area a, and transmits the encoded data to the client terminal 200.

In particular, the full image frame (not direct the video in this case), which is transmitted in advance from the terminal device 100 of the camera is displayed in the unit display 208 of the client terminal 200 by the processing unit 204 controls. When the user operates the block 206 input of the client terminal 200, and determines the selected area And of the full image, the information pane, And is passed to block 204 management. On the basis of the command block 204, the control unit 202 of the transmitting/receiving client terminal 200 transmits the information pane, And in the terminal device 100 of the camera. Next, on the basis of the command block 204 management information region And the corresponding region R2 of the image that will be explained later) is displayed within the full image block 208 display.

When the unit 106 of the transmission/receiving terminal device 100 of the camera through the computer network 300 inform the tion, related to A (called the second information in the claims), it passes this information to the block 108 control. Block 108 control issues a command to the block 104 of the image processing to extract and process coding only for part of the region And image (live video) transferred from the block 102 of the camera. Unit 106 of the transmission/receiving receives a direct video encoded region And from the block 104 of the image processing and transmits live video to the client terminal 200 via the computer network 300.

When the block 202 of the transmitting/receiving client terminal 200 receives the live video pane, And from the terminal device 100 of the camera, it transmits the data block 203 image processing. In block 203, the image processing information of the area And is decoded and the block 204 management conducts a processing for performing a display unit 208 to display. It is necessary to take into account that in this case the region And corresponds to the region R2 of the image that will be explained later.

Thus, the user operates the client terminal 200, and determines the selected area of the full image, and can thus perform digital operations, which is equivalent to performing mechanical operations of pan, tilt, zoom (PTZ). In the result which can be obtained video of the selected area.

In particular, in recent years increased the capacity of the computer network 300, and thus, it is possible to transfer high-definition video with a higher number of pixels. However, when all data of a full image is sent in the form of direct recording, the volume of data is huge. By transferring only the necessary data area defined by the user, as in the present embodiment, it is possible to watch high-definition video for the selected field.

It should be noted that the extraction area And with the help of image processing can be performed on the side of the client terminal 200. In this case, the block 203 image processing (which corresponds to the block 104 of the image processing) is provided in the client terminal 200, and the terminal device 100 of the camera encodes the image (live video) transferred from the block 102 of the camera, and transmits the coded data of the block 106 transmitting/receiving in a computer network 300. When the user operates the block 206 input of the client terminal 200, and determines the selected area And of the full image, the block 204, the control sends the command unit 203 of the image processing to extract the region A. When the unit 202 receiving/sending client terminal 200 receives a direct filming, it transmits a direct recording unit 203 of the processing of the images, and the area And retrieved by the block 203 image processing. The image of the extracted area And is passed from block 204, the control unit 208 of the display and is shown in block 208 of the display.

Further, in the system of this variant implementation in addition to the digital operations of pan, tilt, zoom can be done with mechanical operation of pan, tilt, zoom. As shown in Fig.2, the terminal device 100 of the camera is provided with a mechanical device that can change the direction of the optical axis of the optical system forming the image in the direction of pan and tilt. In addition, the terminal device 100 of the camera is provided with a mechanical device that can move the optical system with variable focal length optical system forming the image in the direction of the optical axis. Data mechanical devices included in block 102 of the camera shown in Fig.2, and is formed of drive mechanisms such as a motor and gears. Mechanical operation of pan, tilt, zoom can be performed by block 102 of the camera terminal device 100 camera, which manages data of mechanical devices in accordance with the commands of block 108 of the control.

Similarly to the above-described digital operation the pits panning, tilt, zoom mechanical operations of pan, tilt, zoom can be controlled from the client terminal 200 by determining the area within a full image of the client terminal 200.

In particular, when the user operates the block 206 input of the client terminal 200, and determines the selected area And of the full image, the block 202 of the transmitting/receiving client terminal 200 transmits information (first information) of the region And the terminal device 100 of the camera on the basis of the command block 204 management. Moreover, on the basis of the command block 204 management information region (corresponding to region R1 of the image that will be explained later) is displayed within the full image in block 208 display.

When the unit 106 of the transmission/receiving terminal device 100 of the camera through the computer network 300 information related to A (first information), it transfers to block 108 control. On the basis of the information area And the block 108, the control issues a command for positions of pan, tilt, zoom block camera 102 unit 102 of the camera. At this time, the block 108, the controller may issue a command to positions of pan, tilt, zoom in accordance with the position of the region And within the full image Yves accordance with the size of the area A. The block 102 of the camera controls the mechanical positions of pan, tilt, zoom based on the information region A. it is Necessary to take into account that in this case the region And corresponds to the region R1 of the image that will be explained later.

Fig.3 is a diagram that shows a state in which many of the client terminal 200 is connected to network 300. Each of the client terminals 200, shown in Fig.3, may perform mechanical operations PTZ, digital PTZ operation by defining a selected area of the full image. It should be noted that in this case it is assumed that the teams from each of the client terminals 200 in conflict, and this situation will be described in more detail in the third embodiment.

2) Processing in the present embodiment,

Next will be explained the processing according to the present variant implementation. Fig.4 is a diagram that shows the display screens of each of the client terminals 200. Above the whole image and a partial image are both displayed on each of the client terminals 200. In Fig.4 total full image is displayed on the client terminal 200, and the individual partial image is displayed on each of the client terminal is 200.

The full image is a wide-range image is fixed in advance by the terminal device 100 of the camera, and represents, for example, a panoramic image, recorded in a very wide range, for which you can perform mechanical operations of pan, tilt, zoom terminal device 100 of the camera. The full image can be obtained, for example, by performing the mechanical PTZ operations of the terminal device 100 of the camera to capture multiple images with different directions of the optical axis and the connection of this set of images.

On the other hand, each of the partial image is an image of a certain range, which is defined from the full image by the user of each of the client terminals 200, and can select a different range for each of the client terminals 200. Fig.4 is a diagram that shows the position in which the whole image and the partial image shown on each terminal clients a, b and C corresponding to each of the client terminals 200. In the example of Fig.4 is a partial image corresponding to the region And the full image is displayed on the client terminal a, And a partial image corresponding to the region In the floor of the th image, displayed on the client terminal C. Similarly to the client And a partial image corresponding to the region And the full image is displayed on the client terminal C.

And the whole image and a partial image displayed in block 208, the display of each terminal clients. In the example shown in Fig.4, a partial image of the customer and the full image is displayed on the client terminal a, And incomplete images of other clients are not displayed. However, in the case of an administrator or similar, incomplete images of other clients may be displayed on the client terminal A. Further, as will be described later, it is possible to display areas corresponding to the partial images of other clients within the full image displayed on the client terminal A. Thus, at the terminal of the client And can be detected region of incomplete images of other clients.

Fig.5 is a graph which shows the full image and a partial image displayed on each of the client terminals 200. As shown in Fig.5, and the region R1 of the image formed by the mechanical PTZ, and the region R2 of the image formed by the digital PTZ, displayed on the full image displayed on each of the client terminals 200. Region R1 of the image formed by Electromechanical what mi PTZ, specifies the image area formed by the mechanical movement of the terminal device 100 of the camera, and specifies the area of the image in the position in which digital PTZ operation is not performed. In other words, the region R1 of the image formed by the mechanical PTZ corresponds to the area of the image that is displayed when the positions of pan, tilt, zoom in accordance with the mechanical processing of the terminal device 100 cameras are the same. Thus, when the mechanical positions of pan, tilt, zoom terminal device 100 of the camera is changed, the range of the image area R1 is formed by mechanical PTZ changes.

As described above with reference to Fig.3, in the system of the present case for many of the client terminal 200 is connected with one terminal device 100 of the camera. Therefore, the region R1 of the image formed by the mechanical PTZ, corresponds to the mechanical positions of pan, tilt, zoom one terminal device 100 of the camera and has the same range on each of the client terminals 200. Thus, the same region R1 of the image displayed within the full image displayed on each of the client terminals 200.

On the other hand, the region R2 of the image is to be placed, educated digital PTZ corresponds to the area of the image that represents the section extracted by the digital operations of the region R1 of the image formed by mechanical PTZ. As a result, mainly, the region R2 of the image formed by the digital PTZ, is a more narrow range than the region R1 of the image formed by the mechanical PTZ. When the area R2 of the image formed by the digital PTZ, set within the region R1 of the image formed by mechanical PTZ, region R2 of the image is extracted from the region R1 of the image display by the image processing performed by the terminal device 100 of the camera or the client terminal 200. Incomplete image shown in Fig.4 and Fig.5, correspond to the R2 image formed by the digital PTZ, which is extracted in accordance with the determination by the user, from the region R1 of the image formed by mechanical PTZ. Unit 204 controls the client terminal 200 may be operated to effect the display unit 208 of the display so that the status display region R1 of the image and the region R2 of the image different. For example, mapping can be performed so that the external shape of the region R1 of the image and the region R2 images have different color. Thus, the user can visually distinguish the region is here R1 image and the region R2 of the image.

As shown in Fig.5, within the full image displayed on each of the client terminals 200, together with the region R1 of the image that is common to all of the client terminals 200 and which is formed by mechanical PTZ, also displays the region R2 of the image, which is formed digital PTZ and is set within the region R1 of the image. By the control unit 206 of the input (which is a mouse, keyboard, or etc.) of the client terminal 200, the user can specify the region R1 of the image and the region R2 of the image of the full image and can change the region R1 of the image and the region R2 of the image on the selected range. Further detail will be explained the definition and change the region R1 of the image and the region R2 of the image.

3) the Method of control 1

Fig.6 is a diagram that shows the control mode 1 region R1 of the image and the region R2 of the image. In the control method 1, in order to set the region R1 of the image and the region R2 of the image are separately two types of PTZ operations. Next will be explained a case where the user performs the operation by PTZ mouse control.

In the case where the user specifies the region R2 of the image and performs digital PTZ operation, when the control region R2 of the image is performed in the pre is Elah region of the display region R1 of the image, operations that change the region R2 of the image are performed until the region R1 of the image remains unchanged. When the user specifies the region R2 of the image within the range of the region R1 of the image area R1 of the image is not changed, and mechanical PTZ position of the terminal device 100 of the camera do not change. Thus, when the user selects the region R2 of the image within the range of the region R1 of the image area R2 of the image specified from the area R1 of the image by image processing, it is retrieved and displayed in the form of an incomplete image without performing mechanical operations. In this case, when the region R1 of the image does not change even if another user, such as a client shown in Fig.4 shows in the form of a partial image region R2 of another image, this other user can continue without problems, to see a partial image.

In addition, when the user specifies the region R1 of the image, and performs the operation PTZ until the display region R2 of the image is within the range of the image, digital operations RT is defined, and mechanical operations performed RT to change the region R1 of the image.

Further, in the case where the user specifies the region R2 of the image and performs digital operations the purpose of the RT, when panning and tilting are performed outside the display area of the mechanical operations of RT, i.e., when the user tries to expand the definition of region R2 of the image outside the range of the region R1 of the image, the mechanical operation of the RT are performed together with the digital operations of the RT, and the region R1 of the image caused by the change so that the area R2 of the image is within the region R1 of the image. Thus, when the user operates the region R2 of the image, and performs the operation PTZ outside the display area of the region R1 of the image, set the image outside the range of the region R1 of the image, and thus operations are performed to change the mechanical PTZ positions of the terminal device 100 of the camera.

As a separate example, when the control region R2 of the image, the operation of the RT region R1 of the image can be performed regardless of, that is the area R2 of the image within the region R1 of the image or not.

In addition, in the case where the user specifies the region R1 of the image and performs mechanical operations of the RT, when the area R2 of the image formed by digital RT, is outside the scope of the display region R1 of the image, digital operations performed RT together with the mechanical operations of the RT, so obrazovkova change region R2 images what region R2 of the image is within the region R1 of the image.

With the above operations, the user can perform the mechanical operation of the RT or digital operation RT by defining respectively the area R1 of the image and the region R2 of the image. However, in the case in which control of one area of the region R1 of the image or a region R2 of the image makes it difficult to display a different area of the image by combining the changes that other areas of the image it is possible to constantly set the area R2 of the image within the region R1 of the image.

Define and modify a region R1 of the image and the region R2 of the image is achieved by the user using the mouse to perform the operations of selecting and dragging on the full image. For example, in the position in which the selected region R1 of the image (or region R2 of the image) by clicking the mouse on the selected point within the full image, the user can move the center region R1 of the image (or region R2 of the image) at the position of this selected point. Conversely, in the position in which the selected region R1 of the image (or region R2 of the image), the user can perform a drag operation to make the region R1 of the image (or region R2 of the image) to move to the selected position.

PR is this, when the selected point is marked on the full image, if the point is within the region R1 of the image, the center of the region R2 of the image (digital RT) may coincide with the marked position, while the region R1 of the image (mechanical RT) is unchanged. If the marked position is outside the display area of the region R1 of the image, and mechanical and digital operations can be performed so that the centers of both mechanical and digital display areas will coincide with the marked position.

In this case, the center of the region R2 of the image formed by digital RT coincides with the marked position, while the center region R1 of the image formed by mechanical RT is not necessarily marked position. Conversely, mechanical RT can be performed so that the region R2 of the image just fits within the region R1 of the image. Thus, it is possible to minimize the amount of mechanical control RT.

In terms of scaling operations, mainly when set to manual or digital scaling operation (when specified area R1 of the image or region R2 image), control scaling is performed only for scaling on a given side like the above-described operations of the RT.

Further, if the mechanical is whether digital scale operations is not specified, when issued the command to perform scaling operations, performed first mechanical scaling within the range of the possible mechanical scaling, thus changing the region R1 of the image. So the image and within the region R1 of the image, and within the region R2 of the image increases, and the range corresponding to the region R2 of the image is displayed as a partial image. Further, when the mechanical scaling peaked in the direction of the photographic telephoto (zoom in) (when mechanical scaling has reached the end position of the photographic lens), to further increase the range of region R2 image processing using digital zoom.

In the control method 1, when the area R2 of the image is set and the region R2 of the image moves, while the region R1 of the image moves only to the minimum range, the load to the other client terminal 200 can be minimized if the other client terminal 200 performs digital PTZ operation.

4) the Method of control 2

Fig.7 is a diagram that shows the control mode 2 region R1 of the image and the region R2 of the image. In the control method 2 mechanical PTZ operations and digital OPE is the Nations PTZ must be managed in cooperation with each other. In Fig.7 even in the case where we have one area - the area R1 of the image (mechanical RT) or region R2 of the image (digital RT) - and this area is moved, the mutual location of the region R1 of the image and the region R2 of the image remains in the same state, and the region R1 of the image and the region R2 of the image is moved in parallel.

For example, in a state in which the selected region R1 of the image (or region R2 of the image), if the user marks the selected point on the full image, it is possible to move the center of the region R2 of the image on marked point while maintaining the relative position of the region R1 of the image and the region R2 of the image in the same condition.

Further, when performing the scaling operation, if one area is the area R1 of the image (mechanical RT) or region R2 of the image (digital RT) - and this area is moved, the scaling operation is performed so that the ratio of the scale region R1 of the image and the region R2 of the image is constant.

In the control method 2, when the terminal device 100 camera monitors and records the specified object, as the region R1 of the image and the region R2 of the image are shifted to the tracked object can reliably track within the region R1 of the image. Even if you are tracking the first object temporarily moved outside the region R2 of the image, as the region R1 of the image is shifted from the region R2 of the image by the recording region R1 of the image, it is possible to consistently obtain an object that cannot be tracked.

As described above, according to the first variant implementation is possible for the client terminal 200 to set the mechanical operation of the zoom and the digital zoom operation and to perform the selected control. As a result, in the system where possible mechanical and digital scale operations, it is possible to obtain an image of the desired range. 2. The second option exercise

1) Overview of the second variant implementation

Next will be explained a second variant implementation of the present invention. In the second embodiment, the terminal device 100 camera has no mechanical pan and tilt, and has only a mechanical function zoom (optical zoom). Fig.8 is a diagram which shows a configuration of the terminal device 100 of the camera, when the terminal device 100 camera only has a mechanical zoom function.

As shown in Fig.8, digital PTZ operation is performed within the video, which is obtained by the lens of the camera terminal device 100 of the camera. In this case, according to whom the n'doye from the client terminal 200, the part of the video (region A, it is shown in Fig.8) obtained from the lens of the camera terminal device 100 camera, retrieve and transmit to the client terminal 200. It should be noted that in the video it is also possible that all the video received from the camera lens, transmit to the client terminal 200, and the area And get all the video and display the receiving side client terminal 200.

Fig.9 is a graph which shows the full image on each of the client terminals 200. Similar to the first variant of implementation together with the region R1 of the image formed by mechanical Z, region R2 of the image that is set within the region R1 of the image and which is formed digital PTZ, is also displayed within the full image. In the second embodiment, the machining operation pan and tilt cannot be performed, and thus the region R1 of the image formed by the mechanical PTZ, is always displayed in the center of the full image. It should be noted that in Fig.9 shows only the full image, but similar to Fig.5, and the full image and a partial image are both displayed in block 208, the display of each of the client terminals 200.

2) the Method of control 1

Fig.10A-10E are diagrams that show the way control 1 region R1 image < area R2 of the image according to the second variant of implementation. In the control method 1 determination region R1 of the image formed by the mechanical operation of the optical zoom, and the definition of region R2 of the image formed by the digital PTZ operations are performed separately.

First of all, Fig.10A, if the digital operation of the RT region R2 of the image within the display area of mechanical scaling region R1 of the image, digital PTZ operation area R2 of the image are performed until the region R1 of the image is unchanged. Next Fig.10 shows the definition of the region R1 of the image formed by the operation of the optical zoom. In Fig.10V range, in which the region R2 of the image formed by the digital PTZ operations included in the region R1 of the image area R1 of the image can be changed by mechanical operations of RT within the range indicated by the arrow.

Fig.10C shows a case where, when the region R2 images change the digital PTZ operations, the operation is performed, in which an attempt was made to continue the region R2 of the image outside the region of the display region R1 of the image. In this case, the operation is performed in interaction, in which the operation of the optical zoom is used to extend the region R1 of the image so that the region R2 of the image is clucene in the region R1 of the image.

Fig.10D shows a case where when the ratio of the display region R1 of the image optical zoom becomes greater than the preset value with respect to the complete image, manual zooming moves the photographic lens in accordance with the area R2 of the image. In this case, when the area R2 of the image moves digital operations RT in the direction of the center of the full image, the optical zooming is performed so that the mapping ratio is approaching above the specified value due to the optical zoom on the side of the photographic lens within the range in which the region R2 of the image included in the region R1 of the image. Thus, it is possible suppress the area of the region R1 of the image formed by the optical zoom, which is more extended than necessary, and thus improve resolution.

Fig.10E shows a case in which the region R1 of the image is controlled by the operation of the optical zoom of the region R2 of the image formed by the digital PTZ, continues outside the region R1 of the image. In this case, the digital operation of the RT through synergy so that the area R2 of the image is at the limit of the x region R1 of the image.

Next, with respect to operation of the zoom, even when set to one area - the area R1 of the image (optical zoom) or region R2 of the image (digital zoom) - and that the scope moves, the scaling operation is performed so that the ratio of the scale region R1 of the image and the region R2 of the image remains constant.

However, when the scaling operation, the first optical zooming is performed within the range of the optical zoom. Then, when the optical zoom is increased to the maximum in the direction of the photographic lens when the zoom operation is then performed in the direction of the photographic lens, is digital zoom.

3) the Method of control 2

Fig.11 is a diagram which shows the control mode 2 region R1 of the image and the region R2 of the image according to the second variant of implementation. In the control method 2 optical zoom and digital zoom can be done in interaction with each other. In Fig.11 scaling operation is performed so that the ratio of the scale region R1 of the image formed by the optical zoom, and the region R2 of the image formed by the digital is m scaling, keeps a constant value.

In this case, even if it is set or mechanical zoom or digital zoom, the centers of the region R1 of the image and the region R2 of the image are relatively constant, and the scaling is performed until the ratio of the scale region R1 of the image and the region R2 of the image is constant.

As described above, according to the second variant of implementation, even when the terminal device 100 camera has no mechanical pan and tilt, it is possible to obtain an image of the desired range using the optical zoom of the terminal device 100 cameras and digital PTZ operations.

3. A third option exercise

1) Display and control when assign the right to control

Next will be explained a third option of implementing the present invention. A third option implementation refers to the case where there is a conflict between teams from each of the above-described client terminal 200, as described above. In this case, in the third embodiment, the right of control is assigned to one of the many client terminal 200 and the client terminal 200 that has the right to control, performs operations PTZ. In other words, in the third embodiment, only the client terminal 200 that has the right to control, exclusively controls the PTZ operations.

In the present embodiment also, similarly to the first and second variants of the implementation can be performed mechanical operation PTZ, digital PTZ operation. For this reason, in the present embodiment, the right of exclusive control may be appointed in relation to the mechanical PTZ operations, and to the digital PTZ operations.

In this case, when the system has one terminal device 100 of the camera, the right to control the mechanical PTZ operations can refrain selected by the client terminal 200. On the other hand, it is possible to assign the right to control digital PTZ operations only selected client terminal 200 or assign the right to control digital PTZ operations to multiple client terminals 200. Here it will be explained in more detail with reference to Fig.12-15.

Fig.12 shows a case where one client terminal 200 has the right management and the region R1 of the image, and the region R2 of the image, and the other client terminal 200 does not have the right to control. In this case, as shown in Fig.12, the client terminal 200 that has the right to control the region R1 of the image and the region R2 of the image, can perform the machining operation PTZ, digital PTZ operation and may be freely controlled and the region R1 of the image,and the region R2 of the image. In this case, it is possible to freely control the region R1 of the image using the mechanical PTZ operations. Further, it is possible to freely control the regulation region R2 of the image area R1 of the image using the digital PTZ operations.

Here, when the area R1 of the image is changed by the client terminal 200 that has the right to control the mechanical PTZ operations, the other client terminal 200 (which has no right to control the mechanical PTZ operations and has the right to control only the digital PTZ operations) can control region R2 of the image within the altered region R1 of the image.

Thus, when one client terminal 200 has the right to control and mechanical operations PTZ, digital PTZ operations, the region R1 of the image and the region R2 of the image can be freely moved, as shown in Fig.12.

Fig.13 shows a case where one client terminal 200 has the right management and the region R1 of the image, and the region R2 of the image, and the other client terminal 200 (in this case one of the other client terminals 200) has the right to control digital PTZ operations.

In this case, if the mechanical PTZ operation is not limited, the other client terminal 200 that has the right to control digital PTZ operations, is unable to perform the required digital operations and PTZ. For this reason, the region R2 of the image (shown as region R2a image in Fig.13) formed by the digital PTZ operations, the right of management which has the other client terminal 200 is displayed on the client terminal 200 that has the right to control the mechanical PTZ operations. Then, to provide the display region R2a image on the other client terminal 200, the region R2a image and the area that includes the region R2a image (a rectangular range With dotted lines in Fig.13), are displayed on the client terminal 200 that has the right to control the mechanical PTZ operations, and mechanical PTZ operation is possible only within the range of the dotted lines. Due to restrictions control to the client terminal 200, which thus has the right to control the mechanical PTZ operations, even when the machining operation PTZ, region R2 of the image formed by the digital PTZ operations, the right of management which has the other client terminal 200, constantly included in the region R1 of the image, and thus the other client terminal 200 may continue to receive a partial image region R2a image.

Similarly to Fig.12, in case, also shown in Fig.13, the client terminal 200 that has the right to control the fur the technical operations PTZ, region R2 of the image can be set within the region R1 of the image using the digital PTZ operations and can be obtained in the form of an incomplete image. Next, as shown in Fig.13, there is a case where one client terminal has the right to control the regions R1 and R2 of the image, and the other client terminal 200 has the right to control the region R2 of the image, in this case, both the client terminal 200, thus, have the right to control the region R2 of the image. In this case, it is possible to freely control on the side of one of the client terminal 200, regardless of whether the client terminal 200 right control region R2 of the image or not. Thus, for example, when an urgent need to see the video of a specific place, while the right control is the other client terminal 200, there is a possibility to avoid the inability to perform the mechanical PTZ operations in the area.

It should be noted that since it is not usually necessary in the display region R2a image and range, indicated by the dotted lines, it is also possible that the region R2a image and the range displayed on the client terminal 200 that has the right to control the mechanical PTZ operations only when the user performs operations PTZ.

Further, since the region R1 of the image will not be made more than the range of the rectangular range, outside range becomes a region which is not assigned to the control. For this reason, as shown in Fig.13, the area outside the range displayed in white (as a variant, it may be displayed in gray or similar), so that it is possible to visually recognize an area that is not assigned the right to control.

Fig.14 shows a case where the client terminal 200 has the right to control the mechanical PTZ operations, and the other client terminal 200 has the right to control digital PTZ operations. In this case, the range in which can be done with mechanical operation PTZ, represents a range (rectangular range, indicated by the dotted line in Fig.14), which includes the region R2 of the image (marked as region R2a image in Fig.14), for which the right to control digital PTZ operations owned by another client terminal 200.

In the example shown also in Fig.14, since it is usually not necessary to display the area R2a image and range, indicated by the dotted line, it is also possible that the region R2a image and the range displayed on the other client terminal 200 that has the right to control the mechanical PTZ operations only when the user performs operations PTZ.

<> Further in the example, also shown in Fig.14, the area outside the range displayed in white (as a variant, it may be displayed in gray or similar), so that it is possible to visually recognize an area that is not assigned the right to control.

Fig.15 shows a case where the client terminal 200 has the right to control digital PTZ operations, and the other client terminal 200 has the right to control the mechanical PTZ operations. In this case, the range in which you can control region R2 of the image formed by the digital PTZ operations, is within the range of mechanical PTZ (region R1 of the image), which is the other client terminal 200. Region R1 of the image is changed by control of the client terminal 200 that has the right to control the mechanical PTZ operations. It should be noted that when the other client terminal 200 has the right to control the mechanical PTZ operations, the image area R1 of the image can be watched at a later stage, for example, by recording the image (the image separately from the region R2 of the image cannot be displayed in advance in the form of direct recording in the field partial image on the server.

2) an Example of assignment of rights management

As described above, with the R2 image is, educated digital PTZ operations, by passing multiple threads of an image from the terminal device 100 of the camera through the computer network 300, a number of different client terminal 200 may receive the video different regions R2 of the image. Fig.16 is a diagram showing the state in which two different videos (video 1 and video 2), corresponding to the region R2 of the image, is transmitted to each of the client terminals 200. Here it is assumed that, for example, video 1 corresponds to the region R2 of the image shown in Fig.13, and the video 2 corresponds to the region R2a image shown in Fig.13.

As shown in Fig.16, when control two video (video 1 and video 2), if a control is available or video 1, or video 2, available right video management is assigned to the next client terminal 200, which comes to the management of video.

For example, when available right control and video 1, and video 2, first entered the client terminal 200 (here, the operator 1 can receive the right to control one of the video video 1 or video 2. Here it is assumed that the operator 1 receives the right to control video 1 and video controls 1. For the time during which the operator 1 holds the right to control video 1, in accordance with the above-described processing, the operator 1 can freely control the range of the m video 1 and can receive live video of the required field.

Next, in a state in which the operator 1 holds the right to control video 1, recently joined the client terminal 200 (here the operator 2) obtains the right to control video 2, because there is the right to control video 2. Thus, for the time during which the operator 2 retains the right to control video 2, the operator 2 can freely control the range of the video 2 and can receive direct video recording of the desired area. It should be noted that when the right control video 1 is not available, even if there is the right to control video 2, it is also possible to wait until the right video management 1 becomes available.

Next, in a state in which the operator 1 holds the right to control video 1 and statement 2 holds the right to control video 2, the next incoming client terminal 200 (here, the operator 3) can't get the controls right, because the right to control and video 1, and video 2 is held by the operator 1 and operator 2. For this reason, the operator 3 is in the ready state until the right to control the video 1 or video 2 becomes available. Regarding the terminal of the client shown in Fig.4, while in the ready state, the client terminal 200 is usually sees the same video as the other client terminal 200 that has control, such as the client terminal A. thus, when operator enters 4,the control receives the order from the client terminal 200, entering into an earlier time, when the control becomes available.

The time during which retained the right of control may be set, for example, in advance. The timer 112 of the terminal device 100, the camera counts the time during which each of the operators accordingly retains the right to control, and when the period of time set in advance elapses, the right operator control is cancelled. Here is an example, when the period of time for retention of the right of control is 15 minutes; in the above example, when the receiving operator 1 rights management video 1 expires 15 minutes, the right to control video 1 operator 1 is cancelled. As a result, the operator 3, which is in the ready state, has the ability to get the right video control 1 and control the video 1. Further, since the operator will receive 2 rights management video 2 expires 15 minutes, the right to control video 2 operator 2 is cancelled. As a result, the operator 4, which is in the ready state, has the ability to get the right video control 2 and control the video 2.

This procedure may be performed when the right control is assigned taking into account the mechanical region R1 of the image. However, it should be noted that since the system has one terminalemulator 100 camera the right control region R1 of the image is assigned to only one client terminal 200. When, for example, available right control region R1 of the image, first entering the client terminal 200 (here, the operator 1 can get the right control region R1 of the image. The client terminal 200 (here the operator 2), which enters into a state in which the operator 1 holds the right to control the region R1 of the image is in the ready state, while the right control region R1 of the image becomes available.

3) Processing relating to the assignment of rights management

When attempting to obtain management rights the user performs the control on the side of the client terminal 200 to select the area R1 of the image or region R2 of the image. Case explained here - when selected, the client terminal 200 shown in Fig.15, receives the right to control video 1 region R2 of the image. Management in this case is, for example, through the use of block 206 of input, such as mouse, keyboard, etc. to determine the external video frame 1, shown in block 208 of the display. However, the present invention is not limited to this example. In response to the above-described operation unit 202 of the receiving/transmitting transmits the terminal device 100 camera information (information request management), about snachalo, what the client terminal 200 tries to get the right video management 1.

It should be noted that when the client terminal 200 tries to get the right video management 2, information (information request management), indicating that the client terminal 200 tries to get the right video control 2, is transmitted to the terminal device 100 of the camera.

Information management request is transmitted via a computer network 300 to a terminal device 100 of the camera, it gets the block 106 transmit/receive, and then it is passed to block 108 control. When the right management was not assigned to the video 1 or video 2, for which issued the request control unit 108 controls assigns the right of control to the client terminal 200 that has transmitted the request information management, and records the IP address of the client terminal 200. Thus, when the block 108 receives control information, which specifies the area of the video 1 from the client terminal 200 that has the right to control unit 108 controls extracts the section corresponding to the specified area of the full image (live video), which is transmitted from the block 102 of the camera, and issues a command to encode only the extracted section of this area. Unit 106 of the transmission/receiving receives the live video pane, And which was executed processing codero the project, from block 104, the image processing and passes through the computer network 300 coded region And the client terminal 200 that has the right to control.

Assigning rights management mechanical region R1 of the image may be performed in a similar way. The user performs management by the client terminal 200 to select the area R1 of the image. The operation is performed, for example, through the use of block 206 of input, such as mouse, keyboard, or similar, to specify an external frame region R1 of the image displayed in the unit display 208. However, the present invention is not limited to this example. In response to the above-described operation unit 202 of the transmitting/receiving terminal transmits the device 100 camera information (information request management), indicating that the client terminal 200 tries to get the right control region R1 of the image.

Information management request is transmitted via a computer network 300 to a terminal device 100 of the camera, it gets the block 106 receiving/transmission, and then it is passed to block 108 control. When the right management has not been assigned region R1 of the image, which is issued by the management information block 108 management assigns the right of control to the client terminal 200 that has transmitted the request information management the Oia, and writes the IP address of the client terminal 200. Thus, when the block 108 receives control information, which specifies the area of the region R1 of the image of the client terminal 200 that is assigned the right control unit 108 controls mechanical control pan, tilt and zoom block camera 102. The block 102 of the camera, thus, transmits the video corresponding to the region R1 of the image block 104 of the image processing. From direct video, transferred from unit 102 of the camera unit 104 of the image processing section extracts corresponding to the area specified by the area R2 of the image, and performs processing coding only for the extracted section of this area. Unit 106 of the transmission/receiving receives a direct video recording region R2 of the image for which the processed coding, unit 104 of the image processing and passes through the computer network 300 encoded region R2 of the image to the client terminal 200 that has the right to control. It should be noted that when the video is removed unit 203 of the image processing of the client terminal 200, after direct video obtained by the block 102, the camera has been encoded, the encoded live video is transmitted to the client terminal 200 via the computer network 300, and the video is extracted the components is 203 image processing.

It should be noted that management configuration according to the third variant of implementation can be applied for the first variant of implementation, and for the second variant implementation.

According to the above third variant of implementation depending on the presence or absence of the respective rights management mechanical operations PTZ digital PTZ operations, it is possible to optimally control the region R1 of the image and the region R2 of the image on the client terminal 200.
