DATA STORAGE CONTROL APPARATUS, DATA STORAGE APPARATUS, DATA READOUT CONTROL APPARATUS, DATA STORAGE METHOD, COMPRESSION CIRCUIT, AND COMPRESSION METHOD

摘要

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.

1. A data storage control apparatus comprising:
a compression element for performing lossless compression for reducing a data amount on image data that is in units of blocks; a determination element for determining whether said lossless compression is possible or not; and a storage control element for performing storage control for, in a case where said determination element determines that lossless compression is possible, causing data obtained through said lossless compression to be stored as compressed data in a storage part, and in a case where said determination element determines that lossless compression is not possible, causing said image data in units of blocks to be stored in said storage part.
