ABSTRACT:
Color compensation is performed in color images for use in an image processing field which is employed for three-dimensional computer graphics and the like by making a luminance value of texture data coincide with an intensity derived by an intensity calculation. Also, lightness compensation is performed for a color image according to a display scene. From measurements 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. The generated image is very natural because compensation is achieved 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.
