Abstract:
A data storage control apparatus includes a compression part that performs lossless compression for reducing a data amount on image data that is in units of blocks, a determination element for determining whether lossless compression is possible or not, and a storage control part that performs storage control for, if the determination element has determined that lossless compression is possible, causing data obtained through lossless compression to be stored as compressed data in a storage part, and if the determination element has determined that lossless compression is not possible, causing the image data in units of blocks to be stored in the storage part.
