The technical field to which the invention relates.

The present invention relates to display the stereoscopic image, which alternately displays left and right images forming a stereoscopic image, the method of time-division using linearly-polarized light in one direction, and to points for the perception of the stereoscopic image with the separation of the right and left fields of view of the displayed stereoscopic image to implement a stereoscopic view, more accurately, to prevent crosstalk that can occur when using linearly polarized light.

The level of technology

Depending on the display system for the perception of stereoscopic images of the right and left fields of view of the stereoscopic image are traditionally separated by displaying on top of each other right and left linearly polarized light beams orthogonal to each other, or right and left light beams with circular polarization, the plane of which rotate in opposite directions, and separately viewed using polarizing glasses, the right and left sides which are orthogonal to each other, or glasses with circular polarization, the plane is on the right and l is howl side rotate in opposite directions. However, in recent years, with increasing speed record displays Nepoklonov type (in particular, LCDS (liquid crystal displays)) right and left images forming a stereoscopic image displayed alternately by the method of time-division even on the screen of the LCD TV Nepoklonov type and so on, and attempted separation of the right and left fields of view using separate fields of view points (for example, glasses with liquid crystal shutter for stereoscopic viewing.

However, because the glasses with liquid crystal shutter uses two polarizing plates on top of each other, their disadvantage is a significant weakening of the captured light and darkening fields of view. In addition, the glasses shutter light beam (polarized light), noise polarizing plate, is sent on their front surface in the direction orthogonal to the direction of the polarizing plate on their back surface, when the field of vision closed to alternately open and close field of view. Given this function, the shutter opening time is reduced by half or more and the light is attenuated. This function shutter interrupts not only the stereoscopic image, but also light environment. Accordingly, in terms of lighting the Deposit is flickering, appearing at industrial frequency.

In the display Nepoklonov type is difficult to simultaneously display right and left images (however, there are images displayed polarized light rays in different directions for each row). Accordingly, it was also suggested to display right and left images by the method of time-division using linearly-polarized light in one direction and separately to view it using the points on the side of perception.

However, if the observer randomly tilts his head when using linearly polarized light, it is difficult to avoid crosstalk (see, for example, patent document 1).

In addition, people have different visual acuity (in diopters). However, existing glasses to perceive a stereoscopic image does not have a corrective optical power of the lens. Accordingly, in these cases, glasses for stereoscopic images are usually used over your regular glasses.

Summary of the invention

Technical task

As described in the previous section "prior art", glasses for viewing stereoscopic images displayed by the x method of time-division on the same screen, have the following two drawbacks, like glasses with liquid crystal shutter: a) the field of view is dark, b) flicker occurs.

In the method described in patent document 1, overcome the mentioned two drawbacks inherent in glasses with liquid crystal shutter, but it has the following new drawback:) there crosstalk.

This occurs when the observer tilts his head. In glasses with a shutter of the field of view completely escaped by using two polarizing plates are orthogonal to each other, when the field of view is closed. On the other hand, according to the method described in patent document 1, the fields of view are escaped when they are closed polarizing plate, which is equipped with a TV (because the LCD TV itself display light is polarized, do not want a new polarizing plate was on the front surface points, as in patent document 1), and polarizing plate glasses. When the observer tilts his head, disturbed mutual orthogonality of polarized light LCD and polarizing plate glasses. Accordingly, it is impossible to avoid crosstalk.

Thus, in the basis of the invention is the technical task of creating points for normal viewing stereoscopic images, otobrazheno the time division stereoscopic images, at the same time overcome the mentioned three drawbacks. Accordingly, the present invention is directed to solving this problem.

According to this configuration, the detector angle automatically detects the slope of the points in the image display device to display a stereoscopic image, and correcting the tilt of the liquid crystal cell regulates the rotation of the polarization plane of the displayed image in accordance with the detected value, resulting in a state of inclination is automatically adjusted to a condition similar to the horizontal state.

Advantages of the invention

The invention also provides choice of optimal corrective optical power of the lens depending on the distance to the observed object.

In the invention according to p. 9 corrective optical power of the lens may easily be inserted into the slot in the latch corrective optical power of the lenses on the glasses to perceive the stereoscopic image with the em, that both ends of the corrective optical power lenses have a rounded shape. Due to its rounded shape in combination with the spring installed in the lock, prevents loss of lens of the slots. In addition, to prevent rotation of the lens due to its lower edge in the form of a curve or a straight line with a greater curvature than the curvature of the circumference on both ends. Due to this does not change the astigmatic axis, if applicable astigmatic lens.

Description of embodiments

The purpose of the present invention will be described with reference to the drawings. In Fig.1 illustrates a display device of the stereoscopic image. The display device is a stereoscopic image includes, for example, stereoscopic LCD TV (hereinafter referred to as "stereoscopic TV") and alternately displays left and right images by the method of time-division on the display 14. At the same time, the emitter 12 clock polarized infrared light mounted on the main body 11 of the stereoscopic TV 10 has an infrared polarizing filter 13 attached to its surface, and generates the synchronization signal of polarized infrared light.

In Fig.2 shows a front view 20 points for the perception of stereoscopic image quality is as one of the embodiments of points for the perception of a stereoscopic image according to the present invention. It is shown that left and right are identical polarizing plates 23Rand 23Lthe direction of polarization of which is rotated by 45° relative to the polarization direction of the display 14 stereoscopic TV 10, adjacent, respectively in the right and left fields of view points.

In addition, on the front surfaces of the polarizing plates 23Rand 23Lon top of another set of liquid crystal cells of two types, i.e., opening/closing of the field of view of the liquid crystal cell 21Rand 21Land correcting the tilt of the liquid crystal cell 22Rand 22Lrespectively. On the spectacles frame mounted receiver 27 clock infrared light and a detector angle (which determines the tilt angle of the liquid crystal cell 24, an infrared polarizing filter 25 and the infrared sensor 26).

In Fig.3 schematically illustrates the configuration points for the perception of stereoscopic image shown in Fig.2. It is shown that the receiver 37 clock infrared light receives the synchronization signal using polarized infrared light (signal need not be polarized) emitted by an infrared polarizing filter 13 stereoscopic TV 10. Received synchronization signal PE is udaetsya controller C1, which converts it into a control voltage. The control voltage is applied to the opening/closing of the field of view of the liquid crystal cell 31R31L. Accordingly, the field of view of 30 points for the perception of stereoscopic images are opened and closed synchronously with the displayed images are alternately displayed by the method of time-division on the display 14 stereoscopic TV 10.

If the observer tilts his head, disturbed mutual orthogonality of the direction of vibration amplitude of the displayed image, the rotation of the polarization plane of which is adjusted based on the opening and closing of the field of view, and polarizing plates 33R33Land it is the condition in which you experience crosstalk. However, to prevent crosstalk by adjusting the tilt of points in this proposed invention is illustrated in Fig.3 configuration of the detector angle (including determining the tilt angle of the liquid crystal cell 34, an infrared polarizing filter 35 and the infrared sensor 36) with the use of correcting the tilt of the liquid crystal cell 32R32L. The detector angle adjusts rotation of the polarization plane of clock polarisavenue the infrared light, generated by infrared polarizing filter 13 stereoscopic TV 10, with the use of determining the tilt angle of the liquid crystal cell 34 and analyzes the synchronization signal using an infrared polarizing filter 35, to determine the tilt angle. If there is such a function, the controller C2 first applies a voltage periodically (e.g., several times per second) for determining the tilt angle of the liquid crystal cell 34. If the voltage is gradually increased, the state of rotation of the polarization plane created by determining the tilt angle of the liquid crystal cell 34 is changed and the direction of vibration amplitude of polarized infrared light, missed determining the tilt angle of the liquid crystal cell 34, becomes orthogonal to the polarization direction of the infrared polarizing filter 35. If there is orthogonality, the output voltage of the infrared sensor 36 is declining rapidly, reaching a state, non-state output, and is determined by the angle of inclination. To determine the angle measured voltage, filed at this point, the controller C2 determines the tilt angle of the liquid crystal cell 34.

The controller C2 converts the data, showing particularly the second tilt angle to adjust the tilt, in the control voltage that is applied to correcting the tilt of the liquid crystal cell 32R32L. If the observer tilts his head during the closing of the fields of view violates the orthogonality, and the light beam, which should be blocked, a little seeps through the polarizing plate 33R33L, can result in crosstalk. However, crosstalk, i.e., the leakage of light is adjusted in accordance with the present invention with the adjustment of the inclination of the liquid crystal cell 32R32L, which results in a state of complete orthogonal polarizing plates 33R33L. Accordingly, shielded from the light condition at the time of the closing of the field of view is constantly maintained at the maximum level.

In Fig.4 schematically illustrates the state of rotation of the polarization plane in 30 points for the perception of stereoscopic images. If the display light emitted by the display 14 is described stereoscopic TV, illustrated in Fig.1 is polarized light, wavering, for example, in the horizontal direction, the display light falls on the right and left fields of view of the spectacles shown in Fig.4. On opening/closing of the field of view of zhidkokristal what kind of cell 41 Lin the left field of view, no voltage is applied, as shown, the switch is in open state, resulting in the opening/closing of the field of view of the liquid crystal cell 41Ltransmits the display light oscillating in the horizontal direction after the rotation of its plane of polarization at 90° to create vibrations in the vertical direction (up and down). On the other hand, the opening/closing of the field of view of the liquid crystal cell 41Rin the field of view is energized, as shown, the switch is closed, resulting in the opening/closing of the field of view of the liquid crystal cell 41Rtransmits the display light oscillating in the horizontal direction. The right and left switches are usually installed so that alternately automatically opened or closed synchronously with the display light in response to an infrared light signal. Accordingly, the display light, noise opening/closing of the field of view of the liquid crystal cell 41Ror 41Lalways mutually orthogonal in the right and left visual fields. (However, if the right and left fields of view points for the perception of stereoscopic images also swap the evidence simultaneously with the switching of the right and left images, alternately displayed by the method of time-division on the stereoscopic LCD TV, the left and right images of stereoscopic TV can create interference. To avoid interference with the right and left fields of view points must remain closed for a specified time (slightly exceeding the time during which switch the right and left images of the stereoscopic TV) at the moment when switching left and right images of stereoscopic TV. Accordingly, the display light can not go directly into the orthogonal state.) Also provides a way to turn off backlight stereoscopic TV when switching fields of view points. Shown by the solid line arrow indicates the direction of the amplitude of the displayed light on the near side of each of liquid crystal cells, as shown by the dotted line arrow indicates the direction of the amplitude of the displayed light on its far side.

The right and left display light, missed the above-described opening/closing of the field of view of the liquid crystal cell 41, respectively, falls on correcting the tilt of the liquid crystal cell 42 with mutually orthogonal direction oscillation amplitude. To whom to shows for example, in Fig.4, the display light falls, being in a vibrational state in the vertical (up and down) direction in the left field of vision. At this point, the display light falls, being in a vibrational state in the horizontal (right and left) direction in the right field of view. If correcting the tilt of the liquid crystal cell 42 is, for example, a twist nematic liquid crystal, and its operating range (angle) is 90°, for correcting the tilt of the liquid crystal cell 42 always served the bias voltage, resulting in a display light enters a state of rotation of the plane of polarization by 45°, that is half of 90°. The controller C2 converts the display data mentioned a certain angle, the control voltage, and adds the control voltage to the bias voltage and subtracts the control voltage of the bias voltage to trigger corrective tilting of the liquid crystal cell 42. Since correcting the tilt of the liquid crystal cell 42R42Lare driven in parallel (in the same direction and at the same time with the left and right sides), the display light in the right and left fields of view preserves the mutual orthogonality even after passing through corrective tilt zhidkokristal the ski cells 42. For example, the display light, missed opening/closing the left visual field liquid crystal cell 41Lvaries in the vertical direction and is directed toward the polarizing plate 43Lafter rotation of the plane of polarization by 45° correcting the tilt of the liquid crystal cell 42L(in this case a rotation of 45° is supported by the bias voltage). The direction of polarization of the polarizing plate 43Lfixed at a 45° angle parallel to the direction of vibration amplitude display of light, missed correcting the tilt of the liquid crystal cell 42L. Accordingly, the display light passes through the polarizing plate 43Land enters the open state of the field of view. On the other hand, the direction of vibration amplitude display of light, missed correcting the tilt of the liquid crystal cell 42Rin the right field of view, orthogonal to the direction of oscillation amplitude display of light in the left field of vision. Accordingly, the direction of vibration amplitude display light is right orthogonal polarizing plate 43Rthe polarization direction of which is parallel to the polarization direction of the left polarizing plate 43LThus, the display light cannot pass through Aisuluu plate 43 Rand jump in the closed state of the field of view.

As described above, 30 points for the perception of stereoscopic images is illustrated in Fig.3, carry out the present invention the function of the shutter in relation to the display light stereoscopic stereoscopic TV 10, shown in Fig.1. However, General lighting (ambient light) is a non-polarized light oscillating in all directions orthogonal to the direction of its propagation. Accordingly, the General lighting has no effect opening/closing of the field of view of the liquid crystal cell 31R31Lnor correcting the tilt of the liquid crystal cell 32R32L. Thus, because of the function of the shutter does not decrease the amount of light (traditional glasses with liquid crystal shutter also have the function of a shutter for the light environment, and the appropriate amount of light in the right and left visual fields are reduced by one half or more, if the right and left fields of view are opened and closed alternately). Due to the lack of function of the shutter for the light environment also does not flicker due to mutual interference with lighting. In addition, since we use only one polarizing plate, bright looks not only image in the article is roscopically TV, but also all the fields of view, including the environment. Accordingly, it is much preferable when viewing stereoscopic images associated with the work.

If the display light of the stereoscopic image, the amplitude of which has a horizontal direction, passes through the opening/closing of the field of view of the liquid crystal cell 31Rand 3Lthe direction of vibration amplitude of the transmitted light is horizontal or vertical in the right and left visual fields. More precisely, the field of view has two States, i.e., open or closed. Intermediate state in addition to these two States is undesirable because of the darkening of the field of view or the occurrence of crosstalk. Accordingly, the opening/closing of the field of view of the liquid crystal cell must have a high response rate. For these purposes, the applicable liquid crystal cell of OCB (optically compensated birefringence) type II, a ferroelectric liquid crystal device with stabilized surface (SSFLCD) or shielded from the polarization of the smectic liquid crystal device (PSS-LCD).

Above we have considered the case when the points are arranged horizontally. When the polarizing plate 33R33Ltilted together with the glasses, according to the proper angle different from 45°. Accordingly, during the closing of the fields of view violates the orthogonality. If this happens, you experience crosstalk. When the glasses tilted, during the closing of the field of view is always maintained at the maximum shielded from light state by determining the angle points using sensor angle that is installed on the glasses, and adding the correction tilt control voltage to the bias voltage or subtracting the adjustment tilt control voltage of the bias voltage to adjust the direction of the amplitude of the displayed light directed toward the polarizing plates 33R33Lso he always reached the state orthogonal to the polarization direction of the polarizing plates 33R33Lwhen the fields of view are closed.

Although the slope of the points is adjusted by determining the angle of tilt to adjust the rotation of the polarization plane by adjusting the tilt of the liquid crystal cell 32R32Lfor determining the tilt angle of the liquid crystal cell 34 with a frequency of several times per second can be made of the control voltage (controller C2). This is because the user shakes his head not with the same high speed as when the tilt of the head. Even in the from period when determining the tilt angle of the liquid crystal cell 34 is not supplied control voltage, since it is determined that the tilt angle is intermediate, there must be certain adjusted condition correcting the tilt of the liquid crystal cell 32R32L. The adjusted state is updated when determining the tilt angle is maintained until it is determined the next angle, and this operating state is always maintained constant, resulting in always remains horizontal visual inclination, even when the tilt points in any direction. Accordingly, to prevent the occurrence of crosstalk.

Although correcting the tilt of the liquid crystal cell 32R, 32Llocated behind the opening/closing of the field of view of the liquid crystal cell 31R, 31Lin the embodiment illustrated in Fig.3, one of the liquid crystal cells may be behind another liquid crystal cell.

For correcting the tilt of the liquid crystal cell 32R32Lyou don't need high speed operation. This is because the speed at which the user tilts his head is significantly lower than the response speed of liquid crystal cells described above. With the responsibly fairly traditional twist-nematic liquid crystal. Since the operating range (rotating the plane of polarization) twist-nematic liquid crystal is 90°, an intermediate position between the position in which the head is tilted to the right, and the position in which the head is tilted to the left, is the horizontal position, when the points in a horizontal position may be submitted voltage (bias voltage), resulting in rotation of the polarization plane of correcting the tilt of the liquid crystal cell 32 by 45°, i.e. at an intermediate value.

There is a case where the corresponding applied voltage and the characteristics of the rotation of the polarization plane defining an angle of inclination of the liquid crystal cell 34 and correcting the tilt of the liquid crystal cell 32R32Lcan be disproportionate to each other. However, in this case, the rotation angle of the polarization plane can be accurately adjusted by the program in which the adjusted value adjusted depending on any parameter of the controller C2.

In Fig.5 illustrates another variant of implementation points for the perception of stereoscopic images. On the spectacles frame 50 for the perception of stereoscopic image shown in Fig.5, the mouth is attached to the detector angle, containing determines the tilt angle of the liquid crystal cell 54, infrared polarizing filter 55 and the infrared sensor 56. Points for the perception of stereoscopic images is configured to calculate a data detector tilt angle and the data clock receiver 57 clock (the method for determining the angle of inclination and method of reception of the synchronization signal as such is identical to the methods described above under item (2) using the controller With synchronous actuation opening/closing of the field of view and correcting the tilt of the liquid crystal cell 51R51Lalternate opening and closing of the fields of view of the display light device 10 display the stereoscopic image for the implementation of stereoscopic viewing with simultaneous regulation, resulting in the display light of the display device is a stereoscopic image, the missing opening/closing of the field of view and correcting the tilt of the liquid crystal cell 51R51Lalways reaches a state orthogonal directions of polarization of the polarizing plates 53R53Lwhen the fields of view are closed, shielded from light always reaches its maximum during the closing of the field of view and prevents cross placed the I.

Although the opening/closing of the field of view and correcting the tilt of the liquid crystal cell 51R51Lrequired bystrolyetyascim material, glasses to perceive a stereoscopic image with the above-described configuration may not be applied SSFLCD. This is because the SSFLCD has diesney function and is unable to display the intermediate value (unable to carry out the adjustment of the tilt). Glasses to perceive a stereoscopic image according to the configuration under item 3 may have a smaller number of parts, but due to a slight narrowing of the range of adjustment of the slope compared with the aforementioned configuration under item 2.

The detector angle required for filing a corrective voltage to the one described in the present invention for correcting the tilt of the liquid crystal cell 32R32Lshown on Fig.3, and the liquid crystal cell 51R51Lshown on Fig.5, this may be a gravity sensor (the sensor that determines the slope of the pendulum, etc., and converts it into the electric outlet, or sensor that converts the change in the surface of the liquid in the electric outlet using the liquid surface) and a gyro sensor (for example, piezoelectric gyro sensor). Because the sensors are able to independently determine Hugo is tilt points not as the basis for adjusting the inclination of the required polarized infrared light. Accordingly, in this case, stereoscopic TV 10, shown in Fig.1, does not require an infrared polarizing filter 13.

In Fig.6 illustrates another variant of implementation points for the perception of a stereoscopic image according to the present invention, in which polarizing plates are adjacent in right and left fields of view points. On the front surface of the polarizing plate 63 on top of another set of corrective tilt to the left liquid crystal cell 62 and correcting the tilt of the right liquid crystal cell 68 having opposite directions of rotation. In addition, on the front surface of correcting the tilt of the left liquid crystal cell 62 are installed opening/closing a field of view of the liquid crystal cell 61. The receiver 67 clock receives the infrared light signal emitted by the emitter 12 clock polarized infrared light stereoscopic TV 10, shown in Fig.1, and the controller C1 converts the signal to the control voltage and supplies the control voltage for opening/closing of the field of view of the liquid crystal cell 61Rand 61L, h is usually used to open and close the right and left fields of view. In this case, the right and left display light is the same as with the passage of the right and left display light, respectively, by opening/closing of the field of view of the liquid crystal cell 41R41Ldescribed with reference to Fig.4. In this state, the respective directions of the amplitude of the right and left display light always mutually orthogonal. Polarized right and left of the display light, which varies mutually orthogonal, passes through corrective tilt to the left liquid crystal cell 62Rand 62Land correcting the tilt of the right liquid crystal cell 68Rand 68,L. However, if corrective tilt to the left liquid crystal cell 62Rand 62Land correcting the tilt of the right liquid crystal cell 68Rand 68,Lno voltage is applied, correcting the tilt of the left liquid crystal cell 62Rand 62Lonce it rotates the plane of polarization of the display light, and correcting the tilt of the right liquid crystal cell 68Rand 68,Lreflect it in the direction opposite to the direction of rotation of the adjustment tilt to the left liquid crystal cell 62Rand 62L. This state is similar to the case when is not set cor is enterouge lean to the left liquid crystal cell 62 Rand 62Land correcting the tilt of the right liquid crystal cell 68Rand 68,L. The left and right images, which are analyzed polarizing plates 63Rand 63Land displayed by the method of time-division on the display 14 stereoscopic TV 10 are separate.

If in the above-mentioned state points will be tilted, broken mutual orthogonality of the directions of vibration amplitude display light during closing of visual fields and directions of polarization of the polarizing plates 63Rand 63L, resulting in crosstalk may occur. In this case, correcting the tilt of the left liquid crystal cell 62Rand 62Land correcting the tilt of the right liquid crystal cells 68Rand 68,Lused, for example, a twist-nematic liquid crystal. Correcting the tilt of the left liquid crystal cell 62Rand 62Limplement the correction in the slope of the points to the left, and correcting the tilt of the right liquid crystal cell 68Rand 68,Limplement the correction in the slope of the points to the right, resulting in a tilt points can be adjusted a total of 180°, i.e., 90° right and 90° to the left. In this case, the bias voltage need not necessarily be provided on an adjustment on the left LON liquid-crystal cell 62 Rand 62Land correcting the tilt of the right liquid crystal cell 68Rand 68,L. If instead of two twist-nematic liquid crystals on top of each other, is applied supertwist-nematic liquid crystal (STN) may be used for one liquid crystal cell. Two twist-nematic liquid crystal should be located on top of each other taking into account the need to apply for them bias voltage, when the glasses are in a horizontal position, and a shift of colors and complexity of fine-tuning because of the steepness of the slope, which is typical for supertwist-nematic liquid crystal.

For the above-described adjustment of the inclination of a total of 180°, i.e., 90° right and 90° to the left, should be determined by the angle of 180°. The first determines the tilt angle of the liquid crystal cell 64 and the second determines the tilt angle of the liquid crystal cell 69, which is illustrated in Fig.6 as the detector angle, can also optionally be rotated 180° when using one supertwist-nematic liquid crystal. If supertwist-nematic liquid crystal is used to determine the tilt angle is not taken into account the offset colors. However, supertwist-nematic liquid crystal is not applicable due to the complexity of fine adjustment of the and steepness of slope. Accordingly, as shown, the controller C2 applies a voltage to first determine the tilt angle of the liquid crystal cell 64 and the second determining the tilt angle of the liquid crystal cell 69 after applying the first determines the tilt angle of the liquid crystal cell 64 and the second determines the tilt angle of the liquid crystal cell 69, as shown, and serial or parallel connection of the respective first electrodes defining the tilt angle of the liquid crystal cell 64 and the second determines the tilt angle of the liquid crystal cell 69. Voltage gradually increases, resulting in a polarized infrared light, noise first determining the tilt angle of the liquid crystal cell 64 and the second determines the tilt angle of the liquid crystal cell 69, which are double-stacked on top of each other, is adjusted so that the plane of polarization rotated in the interval from 0 to 180°. Accordingly, the tilt angle is determined by applying voltage to the first determines the tilt angle of the liquid crystal cell 64 and the second determines the tilt angle of the liquid crystal cell 69 after serial and parallel connections liquid crystal cell 64 and 69 and measure voltage at the moment when the output voltage of the infrared is Attica 66, as shown, decreases rapidly and reaches the state, non-state output. The angle of a total of 180°, i.e., 90° right and 90° to the left, can be determined by a function similar to the function provided in the method for determining the angle of tilt points for the perception of stereoscopic images with the aforementioned configuration, illustrated in Fig.3. Of course, the voltage is filed, when the first determining the tilt angle of the liquid crystal cell 64 and the second determines the tilt angle of the liquid crystal cell 69 are connected in series, is doubled compared with when they are connected in parallel (in the case when their respective functions optical rotation are the same). Even when a voltage is applied to the first determines the tilt angle of the liquid crystal cell 64 or the second determines the tilt angle of the liquid crystal cell 69 and then voltage is applied to the other determines the tilt angle of the liquid crystal cell when the voltage reaches (exceeds) a predetermined maximum value, the function is executed, similar to the case when the first and second determining the tilt angle of the liquid crystal cell 64 and 69 are connected in series or in parallel.

When correcting a tilt to the left liquid crystal cell 62R/sub> and 62Land correcting the tilt of the right liquid crystal cell 68Rand 68,Lthat are installed in the respective fields of view points, turn left or right relative to the horizontal position, they are configured to separate work when tilted to the left or tilt to the right, and they need not necessarily be provided bias voltage.

In Fig.7 illustrates the content of a patent application laid Japan No. 2009-274002 (points for the perception of stereoscopic images), previously filed by the applicant of this application, in which the polarizing plate 72 in the vertical direction (up and down) is installed in the right and left fields of view of the spectacles shown in Fig.7(a). To the front surface of the polarizing plate 72 attached to the liquid crystal cell 71R and 71L. In Fig.7(b) depicts the receiver 73 signals for opening and closing field of view points synchronously with the image displayed stereoscopic TV and illustrated a method for determining the angle of inclination. Its function will be described next.

Infrared polarizing filter 13 on the radiating surface of the radiator 12 clock infrared light that is installed on the device 10 to display a stereoscopic image shown in Fig.1, converts the clock germanium / the ACLs light in the polarized infrared light. As shown in Fig.7(a), the polarization direction of the infrared polarizing filters 74Rand 74Lin the receiver 73 signals symmetrically inclined, when the glasses are arranged horizontally. In this case, the corresponding output voltage of the infrared sensor 75Rand 75Lequal to each other. If glasses are tilted from this position to the right or left, there is a difference between the output voltage of the infrared sensor 75Rand 75L. The tilt angle can be determined on the basis of the preceding analysis of the correlation between the difference of the output voltage and slope.

In Fig.8 shows the adjustment of the optical power of the lens, not necessarily installed on the glasses for the perception of stereoscopic images, and the site of its attachment. People have different visual acuity (in diopters). Even in everyday life, many are correcting optical power points. Sometimes the object is observed from a short distance on the small screen of a personal computer, and sometimes with a few larger distances on relatively larger screen of the TV. Also you want to switch points depending on the distance to the object. In particular, a person who uses glasses to read, you want to change the optical power of a corrective lens (change usually use the established points) depending on the distance to the observed object. Accordingly, in glasses to perceive a stereoscopic image, i.e., dividing the field of view with glasses must be used in a variety of corrective optical power points depending on the user. However, in a real situation points to the perception of stereoscopic images put on commonly used glasses. However, used on top of each other glasses of the two types are unstable and cause problems. Accordingly, also can be made for the personal use of glasses to perceive a stereoscopic image with corrective optical power lenses. However, the disadvantage of the fixed adjustment of the optical power of the lenses, made to order, is the fact that designed for personal use glasses to perceive stereoscopic images may not be used by other people (with different visual acuity). Points for the perception of stereoscopic image should be replaced depending on the observed object (TV or PC) even in the case of personal use.

The best way to eliminate the aforementioned disadvantage is the execution of the slot to lock the lens on the front or back surface points for the perception of stereoscopic images, and if necessary, install it adjustments yuusha optical power of the lens. In Fig.8 shows the retaining clip (slot) for fixing the corrective optical power of the lens front surface points for the perception of stereoscopic images. The retainer are molded in one piece with the frame of the spectacles (its main body is not shown). As shown, the latch 80 has a slot 84, which must be inserted corrective optical power of the lens 81Rand 81L. Corrective optical power of the lens 81Rand 81Lthat is inserted into the slot 84, is clamped in the slots 84 using the leaf spring 82. Due to the shape and actions of the leaf spring 82 is simultaneously inserted corrective optical power of the lens 81Rand 81Lnot fall out of the slot even if the glasses upside down.

Corrective optical power of the lens 81 has a right and left ends rounded. Due to the rounded lenses are easily inserted into the slot 84. In addition, the upper and lower edges of the corrective optical power of the lens 81 have rectangular shape to prevent rotation of the adjustment of the optical power of the lenses 81Rand 81L(from a functional point of view, the rectangular shape can only have the bottom edge). This prevents the rotation function is set as the correcting optical power of the lens required astigmatic lens. This is because when correction astigmat the PCA uses a particular direction (angle), and corrective optical power of the lens must be fixed at a certain position in the direction of rotation. As shown, the handle 83 is covered with aluminum construction and is able to identify the lens by increasing the frictional force with the fingers when split the lens into the slots 84, which not only prevents contamination of the lens, but also provides labeling.

Glasses to perceive a stereoscopic image according to the present invention do not respond to General lighting. Accordingly, the field of view of the working environment looks bright in the process performed when observing a stereoscopic image. Thus, the points do not necessarily remove even if the work is not associated with the viewing monitor. Glasses to perceive a stereoscopic image according to this configuration provides excellent action and effect.

In the invention can be made of various modifications, if they do not go beyond being present invention, and, of course, that modifications are encompassed by the present invention.

SUBSTANCE: invention relates to the stereoscopic display, which can display the images characterized by binocular parallax with the time-division multiplexing. At the output of the image for the right eye on the left side of the centre line a light blocking field BR1 is formed, and at deduction of the image for the left eye on the right side of the centre line a light blocking field BR2 is formed. When an observer is located in these areas, the right eye of the ER observer sees separately the image for the right eye, and the left eye of the EL observer sees separately image for the left eye. As a result, even when the observer watches the stereoscopic display by unaided sight, he can observe the stereo-image, while the eyes of the observer are located in the light blocking fields BR1, BR2. The image for the right eye and image for the left eye are combined in the field differing from the light blocking fields BR1, BR2. Some observers can simultaneously observe the stereo-image, if they use glasses for view.

EFFECT: decreasing overall dimensions.

FIELD: medicine.

SUBSTANCE: invention refers to a stereoscopic image generator. A unit 311 for an image projection on the surface of a horopter aims at a non-stereoscopic image projection through a signal line 129 on a cylindrical surface (the horopter) comprising the horopter circumference. The horopter circumference is specified, e.g. with the use of a radius as the horopter circumference data. Besides, the relation of two eyes is specified as an eye distance. A unit 316 for projection on a display surface for the right eye is used for projection of the image projected on the horopter, on the display surface of the right eye. A unit 317 for projection on the display surface for the left eye is used for projection of the image projected on the horopter, on the display surface of the left eye. For this reason, the identical images on the retina are supplied to both eyes to eliminate the effect of physiological stereoscopic elements and to produce a stereoscopic depth.

EFFECT: eliminating the effect of the physiological stereoscopic elements by the image processing using projection transformation.
