Abstract:
An image processing apparatus for converting a color input image or a partial region thereof in accordance with a color gamut of a color image output apparatus, comprising:a correction point calculation part that corrects a conversion target point and calculating a correction point by using correction data corresponding to said conversion target point; a first conversion point calculation part that compresses or expands a conversion target point to a point on a line connecting a fixed point in the color gamut of said output apparatus that can be determined uniquely based on said conversion target point with said conversion target point thereby calculating a first conversion point; a second conversion point calculation part that compresses or expands a correction point to a point on a line connecting said fixed point with said correction point thereby calculating a second conversion point; and a final conversion point calculation part that determines a final conversion point for said conversion target point by using said first conversion point and said second conversion point.
