FIELD: information technologies.
SUBSTANCE: invention relates to encoding and decoding of images. Image encoding device, which performs division of difference information between an image which is a coding object and an image which is a prediction object into a plurality of subunits, and encoding of divided subunit comprises: a unit for encoding information on significant subunit coding information on significant subunit indicating equality 0 all or not all values of differential coefficients related to subunit; unit of encoding information on significant differential coefficient coding information on significant differential coefficient, indicating equality or inequality 0 value of differential coefficient; coding unit values of differential coefficient; and a unit for extracting context retrieves context for encoding information on significant differential coefficient subunit.
EFFECT: technical result is high encoding efficiency.
