To improve the data compression ratio in the data compression/decompression method utilizing the down-sampling process. Image data in a DS area division unit () is divided into a plenty of DS areas and DS areas which are not important are converted into contracted data of the block size by down-sampling in a down-sampling unit (). A relocation unit () allocates two or more contracted data in one DS area, inserts file data into the other portion in the DS area, and removes the DS area where no contracted data is allocated, thereby reducing the entire image size. The image data thus contracted is inputted into a JPEG encoder () and subjected to a DCT process and a quantization process for each block. When performing restoration, decompression is performed by the JPEG decoder and the original location is restored. As for the contracted data, interpolation is performed to restore the image data.

Image compression apparatus

In medical image recording apparatus, exposure unit forms a latent image on film by exposing based on a testing exposure data for correction of density characteristics of the leading edge and/or the trailing edge of film, and heat developer heat-develops the latent image and records it on film, and density measurer measures the density characteristics of the heat-developed testing exposure image, and then, controller determines the correction areas of the leading edge and/or the trailing edge of film based on the result of the density measurement and corrects the density characteristics of the leading edge and/or the trailing edge of film for the correction areas at the image recording stage of a diagnostic image data.
