PURPOSE:To realize visually real lighting effects by simple calculation. CONSTITUTION:Corresponding to the information of an effecting plane to change a shape contained in image control information from the outside, a control part 14 controls the respective multiplication coefficients or addresses of a mixer part 16 and an image memory 17. Corresponding to a control signal from the control part 14, a lighting pattern generator 15 also supplies lighting patterns corresponding to the shapes of plural effective planes decided in advance to the mixer part 16. An output signal from the mixer part 16 is transmitted to one terminal side of an adder 12 while modulating a lighting color signal supplied from an input terminal 11 by a multiplier 13. The adder 12 outputs an output signal adding a video signal from an input terminal 10 and the output signal from the multiplier 13 from an output terminal 18 through the image memory 17. |
