ABSTRACT:
A digital processing color camera includes a matrix circuit for arithmetically processing digital R, G and B video signals, which have been sampled by a clock signal, to provide a digital brightness signal, a first digital color difference signal and a second digital color difference signal. Those signals are subsequently converted by associated digital-to-analog converters into an analog brightness signal, a first analog color difference signal and a second analog color difference signal. Both the brightness signal and the first color difference signal, are delayed a predetermined period of time by digital delay lines inserted between the matrix circuit and the digital-to-analog converter circuit.
