Patent ID: 8749841

Claim:
An image processing apparatus comprising: an image data generator for generating image data to print a color chart having a plurality of color patches of respective colors on a print medium; an input device for entering identification information of one of the color patches, which is selected from the color chart printed based on the image data, as having a color closest to a designated color; a color converter for making a color adjustment of a print based on the identification information entered by the input device; and a setter for setting colorimetric values of the designated color as a reference color, wherein the image data generator generates image data of pixel values calculated such that the color patches are arranged in a two-dimensional pattern on the print medium around the reference color set by the setter, and color differences in an equal color space between adjacent ones of the color patches are represented by a substantially equal interval along a row or column of color patches; wherein the input device enters a judgment result as to whether or not the designated color is present within the range of the colors of the color patches of the printed color chart; and the setter resets a color corresponding to the identification information as the reference color, when the judgment result indicating that the designated color is present and the identification information are entered by the input device.
