Abstract
The present invention makes moving-image coding and decoding with low power consumption possible even when a Context-based Adaptive Binary Arithmetic Coding (CABAC) process is used. A preprocess for coding an image is executed for each macro block (MB), the MB information that is the result of the process is written into a storage unit in the order in which the MBs were processed, and the MB information stored in the storage unit is read out in order of raster and the MBs are coded. When the coded image is decoded, the MBs constituting the coded image are decoded in order of raster, the MB information that is the result of the decoded process is stored in the storage unit, and a decoded information readout process that is a post-process for decoding the image is executed in the order in which the MBs were processed.
