ABSTRACT:
In a TV camera apparatus having an image sensor which photo-electrically converts image sensing light coming from an object, a signal processing circuit which converts a signal output from the image sensor into a luminance signal and color-difference signals and negative-to-positive inverters which invert the luminance signal and the color-difference signals from negative to positive, variable gain amplifiers are arranged within color-difference signal systems to amplify the color-difference signals; and the variable gain amplifiers are arranged to be controlled on the basis of the luminance signal.
