Abstract
A multimode scan converter includes a delay element ( ) for delaying one horizontal line of video signal and selectively re-displaying that line. A multiplexer ( ) is arranged to selectively provide either luminance signal or chrominance signal to the delay element. Output signal from the delay element and output signal from the multiplexer are coupled to a proportioning circuit ( ) which sums the two signals in complementary proportions (e.g. K and 1-K). A second multiplexer ( ), which provides up-converted output luminance signal, is arranged to selectively pass the luminance signal or signal from the proportioning circuit. A third multiplexer ( ), which provides up-converted output chrominance signal, is arranged to selectively pass the chrominance signal or signal from the proportioning circuit.
