PURPOSE:To change a body color in the same environment by using an ordinary computer system by finding a position coordinate on a three-dimensional space formed with a light source color vector and a body color vector, etc., for each picture element value, and performing color change by using four vectors. CONSTITUTION:The color change is performed by estimating a bias vector, the light source color vector Cs in which a point shifted from an origin by the bias vector is set as a start point, the body color vector Cb, and a color texture vector Cd, finding the position coordinate on the three-dimensional space formed with the light source color vector, the body color vector, and the color texture vector for each picture element value, changing the four vectors simultaneously or independently, and using the position coordinates and the four vectors after change. At such a case, since the picture element value is crowded into the body color vector Cb and the light source color vector Cs when each picture element value of a general color image on a three- dimensional three primary color space is plotted, another vector can be extracted from those two vectors. In such a way, the color change applicable even on the ordinary computer system can be performed. |
