Color video signal mixing system
First Claim
1. A color video signal mixing system, comprising:
- (a) receiving means for receiving a first color video signal and a second color video signal at the same time, the first color video signal and the second color video signal each having an image information different from each other;
(b) first separating means for separating a first luminance signal from the first color video signal;
(c) second separating means for separating a first chrominance signal from the first color video signal;
(d) third separating means for separating a second luminance signal from the second color video signal;
(e) fourth separating means for separating a second chrominance signal from the second color video signal;
(f) first mixing means for mixing the first and second luminance signals to obtain a mixed luminance signal;
(g) selecting means for selecting one of the first and second chrominance signals to obtain a selected chrominance signal;
(h) control means for controlling the selecting action of the selecting means; and
(i) second mixing means for mixing said mixed luminance signal and said selected chrominance signal to give a mixed color video signal.

Abstract
A color video signal mixing system wherein a first separating arrangement separates a first luminance signal from a first color video signal; a second separating arrangement separates a first chrominance signal from the first color video signal; a third separating arrangement separates a second luminance signal from a second color video signal; and a fourth separating arrangement separates a second chrominance signal from the second color video signal. A first mixing arrangement produces a mixed luminance signal from the first and second luminance signal; a selecting device selects one of the first and second chrominance signals; a control facility controls the selecting action of the selecting device; and a second mixing arrangement produces a mixed color signal by mixing the mixed luminance signal and the selected chrominance signal.
