Abstract
An image processing apparatus and method for performing color conversion on first image data of a first format to produce second image of a second format different from the first format. Each of the first and second image data represent a pixel of one of a stationary image and a moving image. The method and apparatus generate complementary color data from the first image data for each pixel of an image, determine a minimum and maximum value of the complementary color data, generate hue data representing a hue of each pixel of the image based on the complementary color data, the minimum value and the maximum value, and generate the second image data based on the hue.
