ABSTRACT:
In order to improve image quality of high compression ratio images, a de-blocking process is performed on decoded image data, and then an edge enhancement process is performed on the de-blocked image data. Performing the edge enhancement process after performing the de-blocking process can improve image quality of high compression ratio images.
