PROBLEM TO BE SOLVED: To prevent an effect of inhomogeneity of image reading accuracy in image reading by image reading means so as to improve accuracy in color profile creation and calibration.SOLUTION: The image processor is configured to: determine, based on read images obtained through reading preset images for detection of reading inhomogeneity by an image reading section, inhomogeneity of reading accuracy caused by reading processing by the image reading section; determine, based on the determination result, a color-characteristic determined region 53 that is a region used for color-characteristic determination in the read images by the image reading section; and control an image formation section to form a preset patch image for measurement 51a and then determine color characteristic at the image formation section, on the basis of the images within the color characteristic determined region 53 in the images obtained by reading the preset patch image by the image reading section. |
