Abstract
A block distortion corrector for providing to recovery image data a block distortion correcting process in which a distortion of recovery image data between neighboring image blocks is corrected, the recovery image data being recovered by an expanding process from image data which are compressed and transmitted in units of image blocks corresponding to the prescribed number of pixels, includes an edge detector for detecting whether or not there exits an edge due to the distortion of the image data at a boundary to the neighboring image block by comparing with a reference value a signal level difference between image data of a to-be-processed pixel located at a boundary of neighboring image block and image data of a pixel which is located in an image block different from the image block of the to-be-processed pixel and is in the vicinity of the to-be-processed pixal. The block distortion correcting process is provided to the image data of the to-be-processed pixel located at the boundary to the neighboring image block only when the signal level difference is less than the reference value.
