IMAGE ENCODING METHOD, IMAGE ENCODING DEVICE, IMAGE DECODING METHOD, IMAGE DECODING DEVICE AND DEVICE FOR ENCODING AND DECODING IMAGES Russian patent published in 2019 - IPC H04N19/70 G06T9/00 

FIELD: data processing.

SUBSTANCE: invention relates to encoding and decoding of images. Apparatus for determining the value of a sample adaptive offset (SAO) is disclosed, comprising: at least one processor; at least one memory device containing computer program code, the memory device and the computer program code is adapted to, by operating with at least one processor, instruct the device to perform at least the following: decode an integer indicating the value of the value of the sample adaptive offset (SAO) from the bitstream using a constant probability bypass arithmetic coding; decode a sign parameter indicating the sign of the SAO value from the bitstream using a constant probability bypass arithmetic coding; and determine the SAO value using the decoded integer and the decoded sign parameter.

EFFECT: ensuring the determination of the value of sample adaptive offset (SAO).
