ABSTRACT:
A digital color camera is disclosed, which includes a circuit for generating first, second and third digital color signals, each at a rate of 4f.sub.sc (where f.sub.sc represents a color subcarrier frequency) from the outputs of first, second and third imagers. A circuit forms a digital luminance signal from the first, second and third digital color signals, and a circuit forms a dot-sequential color difference signal with the first and second digital color difference signals appearing alternately every 1/4f.sub. sc from the first, second and third digital color difference signals and a circuit passes a dot-sequential digital color difference signal through a digital filter so as to limit the band widths of the first and second digital color difference signals and the overall circuit provides improved color TV signals which are formed with simpler circuit means.
