IMAGE PROCESSOR, IMAGE PROCESSING METHOD, PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an image processor capable of independently correcting hue conversion quantity in an area between reference hues in each reference hue. SOLUTION: This image processor performs desired image processing of RGB image input data in an RGB color space. A hue deciding part 115 decides a hue of an unconverted color point shown by the RGB image input data, and a hue converting part 120 performs hue conversion of the unconverted color point into a color point on a straight line that is parallel to a side of the RGB color space in accordance with decision results of the hue deciding part 115. The hue converting 120 performs hue conversion of the RGB image input data. Because hue conversion quantity in an area between reference hues can be independently corrected in each reference hue in this way, satisfactory color conversion can be realized in the entire hue spaces.
