IMAGE ENCODING DEVICE, IMAGE ENCODING METHOD, IMAGE DECODING DEVICE, IMAGE DECODING METHOD AND PROGRAM Russian patent published in 2018 - IPC H04N19/00 

FIELD: data processing.

SUBSTANCE: invention relates to encoding and decoding of images. Image encoding device configured to divide an image into one or more slices, each of which includes a plurality of blocks, and encode each slice in blocks, includes a first encoding unit which is designed with possibility to encode blocks included in the first part of the slice, and a second encoding unit configured to encode the blocks included in the second part of the slice, wherein when the second encoding unit encodes the start block in the second part, second encoding unit encodes the start block included in the second part by referring to the first quantization parameter provided for the slice as an initial value, and to which the first encoding unit accesses when the first encoding unit encodes the start block in the first part.

EFFECT: technical result is to provide parallel encoding/decoding as the entire processing.
