Abstract
An image processing apparatus includes a brightness extracting element for extracting information relating to brightness from color image data; an image attribute judging element for judging a light-color image portion in a color image; and a brightness change section which changes brightness of the light-color image portion. The image attribute judging element includes a separating device for separating foreground data and background data from the color image data; and a comparing section which, when a difference in brightness between the foreground and the background separated by said separating device is smaller than a predetermined value, judges the foreground data as data of a light-color image portion.
