Image processing device and image processing program

摘要

There are provided an information acquiring unit that subjects RGB data of each pixel of a color image to HSI conversion and finds color information including at least saturation (S) from each pixel of the color image and a first converting unit that converts the color information of each pixel by shifting the saturation (S) of each pixel of the color image by a predetermined amount. For example, the information acquiring unit acquires hue (H) and intensity (I), additionally to the saturation (S), from each pixel of the color image as color information and the first converting unit shifts the intensity of each pixel so that the center of a hue distribution obtained by plotting the hue (H), the saturation (S), and the intensity (I) of each pixel in a color space coordinate system having a hue axis, a saturation axis, and an intensity axis, moves toward the intensity axis.
