IMAGE ENCODING DEVICE, IMADE DECODING DEVICE, IMAGE ENCODING METHOD AND IMAGE DECODING METHOD Russian patent published in 2009 - IPC H04N7/50 H04N9/64 H04N11/04 

FIELD: information technology.

SUBSTANCE: invention relates to encoding and decoding digital images. A device is proposed for encoding/decoding a dynamic image, in which during compressed encoding through input of data signals of the dynamic image in 4:4:4 format, the first encoding process is used for encoding three signals of colour components of input signals of the dynamic image in general encoding mode and the second encoding process is used for encoding three signals of colour components input signals of the dynamic image in corresponding independent encoding modes. The encoding process is carried out by selecting any of the first and second encoding processes, and compressed data contain an identification signal for determining which process was selected.

EFFECT: more efficient encoding dynamic image signals, without distinction of the number of readings between colour components.
