Method and apparatus for compensating for color in color images.

摘要

The present invention relates to a method and an apparatus for compensating for color in color images for use in an image processing field which is employed for three dimension computer graphics and so on. Conventionally, a color compensation method for color images for use in this field has not made any compensation between a lightness of a texture itself representing a pattern on the surface of an object and an intensity of the surface of the object derived by an intensity calculation when an image is generated, so that the generated image has been extremely unnatural. The present invention performs a color compensation for color images by making a luminance of texture data coincident with an intensity derived by an intensity calculation. Also, a lightness compensation is performed for a color image according to a display scene. From measuring results of color changes of plural colors in a uniform color space, a color change of arbitrary texture data under a chromatic color light source is represented and compensated for.
