摘要

Apparatuses, a computer program product and a method for digital image quality improvement. A digital image quality improvement unit includes an input interface to obtain edge pixels of a pixel domain target block and edge pixels of pixel domain blocks adjacent to the pixel domain target block; a processing unit coupled with the input interface to form a frequency domain substitute block from the edge pixels of the pixel domain target block and the edge pixels of the pixel domain blocks adjacent to the pixel domain target block and to form a pixel domain substitute block from the frequency domain substitute block; and an output interface coupled with the processing unit to place the pixel domain substitute block in position of the pixel domain target block.
