Abstract
An image processing apparatus capable of generating a color-reduced image with high object reproducibility is provided. The image processing apparatus includes a data processing unit configured or programmed to function as a generating unit generating a binary image for judging whether each of pixels constituting an image obtained is a background attribute or a character attribute, a first determining unit determining a first type representative color based on a histogram of RGB values of pixels judged to be the background attribute based on the binary image among all the pixels constituting the image, a second determining unit determining a second type representative color based on a histogram of RGB values of pixels judged to be the character attribute based on the binary image among all the pixels constituting the image, and a processing unit performing a color reduction processing on the image to generate a color-reduced image.
