Claim:
1. An image processing device comprising: a first calculation unit that calculates a first sum which is a sum of light intensities of dispersed lights generated when a pixel light by a target pixel passes through an optical system, based on distance from the target pixel, to calculate a first light intensity by adding the first sum to a light intensity of the pixel light; a second calculation unit that calculates a second sum which is a sum, at a position of the target pixel, of each of light intensities of dispersed lights generated when each of pixel lights by pixels around the target pixel pass through the optical system, based on distance from the target pixel; a combining unit that calculates a second light intensity of the pixel light by the target pixel by subtracting the second sum from the first light intensity; N (N is a natural number) line memories that store images for each line; and a pixel storage unit that extracts, from each of the N line memories, M (M is a natural number) pixels at positions corresponding in the lines to store N×M pixels, wherein the first calculation unit assumes one pixel of the N×M pixels that are stored in the pixel storage unit as the target pixel to calculate the first sum in a range of the N×M pixels.
