Abstract
A composite video signal has a chrominance signal () and a luminance signal (). A method and apparatus are disclosed for adjusting the chrominance signal () to obtain an enhanced chrominance signal () in which at least some transitions in the enhanced chrominance signal () align more closely with edges in the luminance signal () than transitions in the original chrominance signal () align with edges in the luminance signal (). An edge in the luminance signal () of the composite video signal is detected (). The position of the edge relative to a current pixel is detected (). The chrominance of the current pixel is adjusted () in accordance with at least the position of said current pixel relative to the edge to obtain an enhanced chrominance signal ().
