Abstract
In a case where a plurality of colors is included in the color image, the modification unit calculates a gray value difference indicating a difference between two adjacent gray values for a plurality of the gray values corresponding to the plurality of colors and arranged in order from the largest gray value, in a case where the calculated gray value difference is smaller than a threshold value, changes the corresponding gray value so that the gray value difference becomes the same value as the threshold value, and in a case where the calculated gray value difference is larger than the threshold value, changes the corresponding gray value so that the gray value difference becomes small in accordance with the magnitude of the gray value difference.
