VIDEO ENCODING DEVICE AND VIDEO DECODING DEVICE

摘要

In the disclosed devices: an encoding control unit (3) includes in an optimal compression parameter (20a) one conversion block size at which the encoding efficiency is optimal among a set of conversion block sizes defined in accordance with an encoding mode (7), and indicates said conversion block size to a conversion/quantization unit (19); and the conversion/quantization unit (19) segments an optimal predicted differential signal (13a) into blocks of the conversion block size contained in the optimal compression parameter (20a), and performs conversion and quantization processing, generating compressed data (21).
