DEVICE FOR CODING OF IMAGES, DEVICE FOR DECODING OF IMAGES, METHOD FOR CODING OF IMAGES AND METHOD FOR DECODING OF IMAGES Russian patent published in 2013 - IPC H04N7/50 H04N11/04 H04N9/64 

FIELD: information technologies.

SUBSTANCE: decoding stage is carried out to decode the first identifying information, which indicates whether signals of appropriate colour components are independently coded, and to decode the second identifying information in the case when the first identifying information indicates that signals of appropriate colour components are coded independently, the second identifying information indicates whether all colour components are intra-coded, besides, in the case when the first identifying information indicates that signals of the appropriate colour components are coded independently, and the second identifying information indicates that all images of appropriate colour components are intra-coded, the decoding stages generates a decoded image, in which performance of deblocking filtration is off at each border between blocks serving as elements of conversion and quantisation.

EFFECT: improved optimality and efficiency of decoding in case when coded signals of a dynamic image do not have a difference in respect of a number of counts between colour components.
