ARITHMETIC DECODING DEVICE, ARITHMETIC DECODING METHOD, ARITHMETIC CODING DEVICE, ARITHMETIC CODING METHOD, AND STORAGE MEDIUM

摘要

A coefficient presence/absence flag decoding unit, included in a quantized residual information decoding unit which reduces a processing amount related to coding and decoding of a transform coefficient, splits a target frequency domain or a target pixel domain into sub-blocks, and derives different context indexes with respect to each transform coefficient in a pixel domain, obtained through a transform skip or a transform/quantization bypass, and each transform coefficient which is obtained for each frequency component through frequency transform.
