A image data storage device includes an image data input unit, an image data recording unit, a compression processing unit, a region decision unit, and a compression control unit. The image data input unit receives input of image data. The image data recording unit records image data inputted by the image input unit. The compression processing unit compresses image data to be recorded in the image data recording unit. The region decision unit decides whether or not image data which has been inputted by the image input unit is image data related to an edge portion region of an image. And the compression control unit controls the compression processing unit so that compression processing is canceled for image data which has been decided, by the region decision unit, to be image data related to an edge portion region of an image.
