Patent ID: 8818128

Claim:
An image processing apparatus configured to perform processing for reducing color fringing in a color image that contains a plurality of color components, said image processing apparatus comprising: an estimator configured to estimate a color fringing amount caused by two color components in the plurality of color components; a reducer configured to reduce the color fringing in the color image by a correction amount that is based upon the color fringing amount that has been estimated by the estimator; and a correction amount obtainer configured to obtain the correction amount based upon the color fringing amount estimated by the estimator so that a color infringing region in the color image after the color fringing is reduced by the reducer is positioned in a restricted area in a chromaticity diagram, wherein where a first line passes a first point in the chromaticity diagram corresponding to a target pixel of the color image before the color fringing is reduced and an origin representing an achromatic color in the chromaticity diagram, the restricted area in the chromaticity diagram is located on a side of the origin with respect to a second line that is perpendicular to the first line and passes the first point, and held between two third lines that are parallel to and hold the first line, and are separated from the first line by an equal distance that is equal to or smaller than half a distance between the origin and the first point, the restricted area being held by two lines each of which passes the origin and represents a boundary between a corresponding one of the two color components and an area representing a color component made by mixing the corresponding one of the two color components and another color component with each other.
