Abstract
According to one embodiment, there is provided an information processing apparatus capable of processing image data involving a plurality of blocks. The apparatus includes a difference value detection unit which detects a difference value between pixel values of two adjacent pixels that are arranged via a block boundary contained in the image data in a direction perpendicular to the block boundary, and a correction unit which corrects pixel values of a plurality of pixels that are arranged via the block boundary in the direction perpendicular to the block boundary by distributing the difference value detected by the difference value detection unit to the plurality of pixels.
