Images are produced in a multi-level codec of the first flow with the first dynamic range and the first colour space, and the second flow of the image with the second dynamic range. The first flow of the image is produced by performance of a local tonal display on the second flow of the image, using the functional form that displays a family of curves of the tonal image, parametrised by means of one parameter, besides, the first dynamic range is less than the second dynamic range, and the first flow of the image is in the base layer, and the second flow of the image is in the expansion layer. The multi-level codec includes a decoder and a coder. The first flow of the image is coded in the base layer using a coder to produce the coded first flow of the image. The coded first flow of the image is decoded using a decoder to produce a decoded first flow of the image. The decoded first flow of the image is converted from the first colour space into the second colour space of the second flow of the image to produce the colour first flow of the image. Parameters of the reverse tonal image are generated on the basis of the converted colour flow of the image and the second flow of the image, where parameters of the reverse tonal image approximate the second flow of the image when applied to the converted colour flow of the image. |

Disclosed is a method of forming a composite image based on a separate image, wherein a separate image is obtained, the separate image is compared with a composite image, a mismatch value is obtained based on pixel-by-pixel comparison of the separate image and the composite image, and the mismatch value is decreased by changing at least the combined image or the separate image. |

Method of obtaining digital image with large dynamic range Invention relates to a technique of obtaining digital images of an object, primarily for aerographic and reconnaissance purposes. An image with a large dynamic range is formed by summing images of an object obtained at different exposures, which are modified to the real brightness. The value of the parameter which determines capturing efficiency is determined for each pixel of each image. The most informative elements of each image are assigned the maximum weight coefficient during summation. |

Device and method to process images and device and method of images display Device comprises a module (101) for detection of a movement vector, which detects a vector of movement in each earlier specified area between frames of the introduced image signal, and a module (2) for identification of circuits, which emphasizes a high-frequency component of the introduced image and a signal of an interpolated image, formed by means of a module (100) for conversion of frame frequency (FRC-module), according to the value of movement of the introduced image signal detected by means of the module (101) for detection of a movement vector. This is compensated by a high-frequency component weakened by means of an image sensor effect of integration in time, to reduce visible blur of moving object images to increase sharpness of a displayed image. By setting an extent (a level) of the interpolated image signal circuits as a lower extent of the signal of the introduced image, the sharpness of the displayed message increases without isolation of the interpolated image signal image deterioration. |

Method and device for creating images with high dynamic range from multiple exposures Sufficient light is obtained through several first exposures together with one second exposure in quick succession. The first exposures are combined to provide sufficient brightness and sharpness. The second exposure is meant for collecting colour information. The first exposures are combined with the first exposures to provide an improved image. |

Method and system for adaptive reformatting of digital images Invention is related to the field of image processing and may be used to edit image, when dimensions, proportions and mutual location of most important objects are not violated. In method and system for adaptive reformatting of digital photos and images of documents, rule is selected for calculation of cost function for pixel depending on results of image analysis; cost and history maps are generated; image dimensions are varied by addition / removal of at least one found path with application of interpolation, using both horizontal and vertical paths. Horizontal path is the chain of connected pixels, in which initial pixel of path is located on the left border of image, the final pixel of path - on the right border of image. Number of pixels in path is equal to width of image in pixels. Vertical path is the chain of connected pixels, in which initial pixel is located at upper border of image, the final pixel of path - at lower border of image. Number of pixels in path is equal to height of image in pixels. Searching of path is carried out by minimisation of total cost of path pixels. Generation of cost and history maps is repeated, as well as stages of image size variation, until one of two results is achieved: required image size is obtained; total cost of path exceeds preset threshold. |

Invention is related to system and method for generating of image with expanded dynamic range (EDR) from grouped sequence of scene images, even with motion of scene or camera between images. Technical result consists in creation of better method for fixation of full radiation of static scene to create of EDR map. The said result is achieved due to the fact that one of images is selected as a reference image, every non-reference image is matched with one of the other images, as well as with reference image, which shows exposition, which is closer to this reference image than the one of considered image, and is closest among other images to exposition of considered image, generating field of flux. Fields of flux, which are generated for non-reference images, that are not any longer matched with reference image, are fixed for matching each of them with reference image, and every non-reference image later is changed with the help of flux field connected with it. Reference image and altered images are combined to create of luminosity chart that represents EDR image. |
