Abstract:
1. An image processing apparatus, which applies correction processing to input image data, comprising: a compression unit configured to compress the image data based on values of pixels and a layout of the pixels for each tile including the predetermined number of pixels; a representative value calculation unit configured to calculate a representative value from the values of the pixels included in the tile; a determination unit configured to determine based on a distribution of the representative values of tiles included in a first area including the first number of tiles whether or not a tile of interest included in the first area is to be corrected; a correction value calculation unit configured to calculate a correction value for the tile of interest based on the representative values of tiles included in a second area including the second number of tiles; and an addition unit configured to add representative values of the tiles, determination results of the tiles by said determination unit, and the correction value to the image data compressed by said compression unit.
