ABSTRACT:
During the carrying out of a dim effect, a signal generated at a generator is mixed with a video signal and a matt signal at a mixer, a key signal and background signal are added at an adder, and the resultant signal is outputted. During the carrying out of a fade effect, in similar manner, the signal is mixed with the key signal and a fixed value signal at the mixer, the video signal and background signal are added at the adder, and the resultant signal is outputted. Extended dim effect and extended fade effect give depth to a picture with a color approximation where the depth of the image does not completely merge into the background.
