Title:
符号化装置
Document Type and Number:
Japanese Patent JP5552078
Kind Code:
B2
Abstract:
A coding device that achieves reduction in a circuit size and in the number of processing cycles is obtained. A coding device includes a first arithmetic unit that calculates a first difference value between an input image and a predicted image with respect to each of blocks having a first block size included in a macroblock to be coded, and a second arithmetic unit that calculates a second difference value between an input image and a predicted image for each of blocks having a second block size larger than the first block size included in the macroblock, and a prediction mode determination unit that determines a prediction mode to be applied to the macroblock, based on the first difference values of the macroblock calculated by the first arithmetic unit and the second difference values of the macroblock calculated by the second arithmetic unit.
