Abstract RU 2613736 C2

FIELD: information technology.

SUBSTANCE: invention relates to encoding and decoding of images. Device comprises: obtaining module configured to obtain information corresponding to block size for target block to be encoded; coding module, configured to encode quantisation parameter of said target block, when information obtained by obtaining module indicates that said target block is smaller than quantisation control block, and sampling parameter, used to control quantization of block in quantisation control block, which comprises target block to be encoded which was not encoded.

EFFECT: technical result is enabling image quality control.
