Abstract
In a method of mixing a graphics signal and a video signal in a ratio alpha:(1-alpha), where the graphics signal is obtained by addressing a color look-up table (CLUT) in which color values (R, G, B) are stored, the number of color values stored for each mixing ratio depends on the mixing ratio so as to obtain an optimum filling of the color look-up table.
