ABSTRACT:
Negative color film is processed in a color telecine camera by the selection of an optical filter which provides equal light transmission for the red and green colors so as to produce equal red and green video signals. The electrical gain of the blue channel is then increased to produce a blue video signal equal to the red and green video signals.
