Abstract
Provided are a memory and a processor connected to the memory to execute a program stored in the memory. The processor classifies each of pixels included in an image into any one region of a region of achromatic color and a region of chromatic color inside a color space, uses the pixels classified into the region of achromatic color to extract a first predetermined number of representative colors, uses the pixels classified into the region of chromatic color to extract a second predetermined number of representative colors, and replaces each of the pixels included in the image with a pixel of a representative color having a smallest difference in pixel value from the pixels included in the image, among the first predetermined number of representative colors and the second predetermined number of representative colors, to generate a color-reduced image of the image.
