Moving image coding device, moving image decoding device, moving image coding method, and moving image decoding method

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. 在使用了CABAC编码处理时，也能够以低功耗来进行动态图像编码、解码。对每个MB执行用于对图像进行编码的预处理，并按照所述MB的处理顺序向存储部中写入作为该处理结果的MB信息，按照光栅顺序读出在存储部中存储的MB信息来对MB进行编码。在对编码后的图像进行解码时，按照光栅顺序对构成编码后的图像的MB进行解码，在存储部中存储作为解码后的处理结果的MB信息，并按照MB的处理顺序执行用于对图像进行
