IMAGE PROCESSING DEVICE AND METHOD Russian patent published in 2017 - IPC H04N19/124 H04N19/119 H04N19/44 

FIELD: physics.

SUBSTANCE: image processing device contains a scheme adapted to install a flag on the basis, that indicates, whether there is a delta quantization parameter, of the current quantization parameter for the current coded block formed by the block separation, in which the greatest coding block is recursively divided into smaller coding blocks; and of the inverse quantization of the quantized data based on the installed current quantization parameter.

EFFECT: preventing the subjective image quality deterioration for a decoded image.
