1. An image processing apparatus, comprising: a transformation unit that transforms color information on an input image signal on the basis of a transformation rule; a correction range calculation unit that calculates a correction range in a predetermined color space on the basis of a positional relationship between source coordinates and destination coordinates in the color space; and a point-based transfer distance calculation unit that calculates the transformation destination coordinates at respective points on the basis of the positional relationship between the source coordinates and the destination coordinates, and a positional relationship between coordinates at the respective points within the correction range and the source coordinates to reflect the calculated transformation destination coordinates on the transformation rule.
