ABSTRACT:
An image processing apparatus has an image input unit which inputs image data corresponding to an input color space, and a color space conversion unit which converts input image data into output image data corresponding to an output color space. A correspondence data input unit inputs representative point correspondence data for relating representative points in an input color space to representative points in an output color space. The color space conversion characteristics of the color space conversion unit are determined on the basis of a plurality of representative correspondence data input from the correspondence data input unit. The plurality of representative point correspondence data are color chart correspondence data which relate specific color chart numbers to the data values of the respective color component data constituting output image data.
