Claim One:
1. A color video camera, comprising: means for picking up an image to provide an image signal, to which a color filter having a plurality of separate color filter elements is attached, means, connected to said picking up means, for generating a first luminance signal, a second luminance signal and color channel signals from said image signal, said generating means including a matrix circuit for producing said first luminance signal, said second luminance signal and said color channel signals from said image signal, said matrix circuit using first matrix coefficients for producing the portion of said second luminance signal related to a red component and second matrix coefficients for producing the portion of said second luminance signal related to another color component, said first matrix coefficients being less than said second matrix coefficients to reduce the red component of said second luminance signal, means, connected to said generating means, for processing said second luminance signal and said color channel signals to provide color difference signals, and means, connected to said processing means, for producing a color video signal in accordance with said first luminance signal and said color difference signals.
