Abstract
PURPOSE:To efficiently compress data by compressing the data after an original image is divided into plural blocks, comparing data quantities before and after compression, and making the compression of the blocks ineffective when the data quantity after the compression is large. CONSTITUTION:The original picture is divided into plural blocks with suitable sizes. The data in respective blocks are compression processed, and the data capacity of the original picture and the compression processed data capacity are compared. When the data capacity of the original picture is larger, the compression processed data are made into the compressed data. On the contrary, when the data capacity of the original picture is smaller, the data of the original picture are made into the compressed data as they are. All the blocks are comparing-processed in the same way. Thus, it is possible to follow a compression encoding system like an MH system or an MR system, and the low-cost and efficient data are compressed.
