Abstract

In a picture coding device that partitions differential information between a picture that is a coding target and a picture that is a prediction target into a plurality of sub blocks and codes the partitioned sub blocks in a predetermined sequence, a significant sub block information coding controller (708) and a calculation encoder (701) code significant sub block information that represents whether or not all the values of differential coefficients belonging to the sub block are zero. A significant coefficient information coding controller (706) and the calculation encoder (701) code significant differential coefficient information that represents whether or not the value of the differential coefficient is zero. A differential coefficient value coding controller (707) and the calculation encoder (701) code the value of the differential coefficient.
