IMAGE ENCODING DEVICE, IMAGE ENCODING METHOD, IMAGE DECODING DEVICE, IMAGE DECODING METHOD AND PROGRAM Russian patent published in 2021 - IPC H04N19/124 

FIELD: image processing computer technology.

SUBSTANCE: invention relates to computer technology for image processing. The expected result is achieved by extracting quantization parameters based on the difference values decoded from the bit stream; and decoding image data using quantization parameters, while an image based on image data is capable of including many parts, each of which includes many blocks.

EFFECT: providing the possibility of parallel decoding as the entire processing, including quantization processing, when blocks are decoded in parallel along the lines.
