ABSTRACT:
The present invention provides an image compression device for performing an image compression process for each one of a plurality of blocks into which an original image picture is divided, the device including image correction section for generating a corrected image picture for reducing a block distortion occurring at a block boundary in a restored image picture generated by decompressing a compressed image picture. The image correction section performs a process for reducing a block distortion occurring at a block boundary between a target block to be compressed and a processed block already compressed and adjoining the target block by: referring to a restored pixel value of a restored image obtained by decompressing a compressed image of the processed block, and at least one of an original pixel value of an original image of the processed block and a corrected pixel value of a corrected image of the processed block; and performing an operation for the restored pixel value and at least one of the original pixel value and the corrected pixel value so as to generate a corrected pixel value of the target block and output a corrected image for the target block.
