FIELD: physics, image processing.
SUBSTANCE: invention is related to decoding device of image data. Decoding device is suggested for decoding of the first coded data received by coding of sequential images data, and second coded data received by coding of interlaced image data that correspond to data of sequential images, in which the first unit of decoding decodes the second coded data, unit of digitisation processing with increased frequency interpolates the first prognostic data of image generated by decoding in the first unit of decoding, for generation of the second data of prognostic image, and the second unit of decoding decodes the first coded data on the basis of the second data of prognostic image generated by unit of digitisation processing with increased frequency, besides the second coding unit generates the second coded data with the help of prognostic image data generated by unit of digitisation processing with increased frequency, which correspond to image data in data of interlaced images, to which the same time mark is assigned as to image data in sequential image data subject to coding.
EFFECT: improved efficiency of sequential image data and interlaced image data decoding.
