IMAGE ENCODING METHOD, IMAGE ENCODING DEVICE, IMAGE DECODING METHOD, IMAGE DECODING DEVICE, AND IMAGE ENCODING AND DECODING DEVICE Russian patent published in 2023 - IPC H04N19/70 H04N19/13 H04N19/91 

FIELD: image encoding/decoding.

SUBSTANCE: parameter of a sample adaptive offset (hereinafter – SAO) type is decoded from a bit stream. A SAO type is determined from the parameter of the SAO type for a SAO value to be added to a value of a restored image pixel. A set of beans with variable length encoding is decoded from the bit stream, using bypass arithmetic encoding with a constant probability, wherein the set of beans is an integer indicating the SAO value. The integer indicating the SAO value is determined based on the set of beans decoded using bypass arithmetic encoding with the constant probability. The SAO value is determined using the mentioned determined integer.

EFFECT: provision of determination of a SAO value.
