Abstract
In order to accomplish a color adjustment capable of determining a color at a high degree of freedom, a variety of color expressions and corresponding input instructions are correlated to reflect the instruction of a color change by a certain expression upon another expression. In order to accomplish a color change considering the changes in the ambience, moreover, each vector of an object color, a light source color, a color texture, an ambient color and an input bias is decided to determine the separated component values of the former three vectors of a picture element value so that the changed color of the picture element value may be determined after the vector change from the separated component values and the changed vectors.
