Abstract
A method of color data mapping in color video signal recording to a video disc. A predetermined different number of color data are mapped onto first and second color maps respectively. Each data is expressed by color gradation in different format between the maps. The format of the gradation in the first map is converted into the format of the gradation in the second map. A difference is taken between the gradation of the colors in the same format between the maps. The difference is then compared with a reference quantity. The color in the first map is judged as to whether it is the same as or close to the color in the second map in color solid if the difference is smaller than the reference quantity. The color data are then mapped onto a third color map onto which no color data is mapped, if the judgment is made.
