Abstract
An exposure control device includes an exposure light amount calculator that obtains, for each of correction points that are associated with a respective one of primary correction values and are separated from each other, a correction factor for correcting the primary correction value of the correction point, based on a pixel value of the correction point, calculates, for each correction point, a secondary correction value based on the primary correction value and the correction factor of the correction point, and calculates a distribution of the secondary correction values on an image based on the secondary correction values of the correction points, and an exposure controller that causes an exposure unit to form a latent image by exposure to light having a corrected light amount obtained by correcting a light amount corresponding to a pixel value of each point based on the secondary correction value of the point.
