Moving picture coding apparatus and moving picture decoding apparatus

摘要

It is an object of the present invention to provide a coding unit and a decoding unit for realizing a coding with high picture quality at a low bit rate. On the coding side, the high frequency band suppression unit (102) controls an amount of generated coding so as to control an amount of generated coding and transmit a degree of suppression. On the decoding side, the high frequency band decoding unit (109) performs high frequency band reconstruction of the image signal according to the degree of suppression so that the high picture quality is realized (FIG. 3).
