Abstract

PURPOSE:To change the color of a color picture without damaging naturality by changing the three primary color values of the respective picture elements of an object in the color picture according to a fixed rule when the three primary color values of a light source color are changed. CONSTITUTION:When the light source color is changed, the color of the object is naturally changed. Namely, when the three primary color values of the light source color in the color picture are changed from (Rs, Gs, Bs) to (Rs', Gs', Bs'), three primary color values (R, G, B) of the respective picture elements of the object in the color picture are changed to (R', G', B') according to an expression I. Thus, a color scenary picture can be changed to the color scenary picture, which is irradiated with the light source of a color different from the original light source, and displayed. Then, a condition in the case that an industrial product is set under an environment to be different from the conventional environment can be checked without really executing the setting.
