Abstract
In an image processing apparatus gradation is represented by binary or multiple values. There is a memory to store correction information including a correction value corresponding to a position of image data. Correction circuitry corrects the image data according to the correction value. The number of bits representing the correction value for gradation is larger than the number of bits used to represent the image data.
