ABSTRACT:
According to one embodiment, an encoding circuit includes a taking-over unit which takes over probability tables of divided regions of a previous frame image of a frame image having divided regions to divided regions of a present frame image, respectively, an acquiring unit which acquires a parameter of an adjacent macro block of the previous frame image when the macro block is located on a boundary between the divided regions, a selecting unit which calculates the parameter of the macro block to select one of probability models in the probability table, and an encoding unit which arithmetically encodes a residual signal in the frame image on the basis of the selected probability model to generate an encoded bit string.
