摘要

A frequency transformation determination unit determines whether a plurality of adjacent transformation target regions with the partition boundary interposed therebetween are integrated or not. A transformation coefficient generation unit generates, by applying one frequency transformation, a transformation coefficient for the transformation target regions where the frequency transformation determination unit determined to integrate.
