ABSTRACT An adaptive chrominance separator is provided which responds to horizontal high frequency luminance detail as well as to vertical chrominance detail. The luminance and chrominance levels are detected and an adaptive decision is made, depending upon the relative levels, of whether to use a bandpass filter, a comb filter or the averaged outputs of both filters, to provide more accurate separation of the chrominance.
