Abstract

A video image encoding device includes a calculation unit for calculating a decoding time of each group including plural blocks; a source encode unit for encoding each of the plural blocks based on the encoding amount of each block controlled based on the decoding time and generating compressed data; and an entropy encode unit for performing an arithmetic encoding process on the compressed data in each block and outputting a bit stream. The entropy encode unit outputs undetermined bits retained by the arithmetic encoding process when all bits corresponding to the compressed data in each group are not output at a time point when the arithmetic encoding process on the compressed data in a predetermined number of blocks in a next group is finished, and the calculation unit shifts the decoding time of each group by a processing time of the predetermined number of blocks.

First claim

What is claimed is:

1. A video image encoding device for dividing each picture included in video image data into a plurality of blocks and performing an encoding process on each of the plurality of blocks, the video image encoding device comprising:
a calculation unit configured to calculate a decoding time of each group including the plurality of blocks;
an encoding amount control unit configured to control an encoding amount of each of the plurality of blocks based on the deco…
