Abstract
A color encoding filter for use with a discrete photosensor pickup device has vertical stripes. The stripes occur in repeating cycles of color order, with the ratio of the width of a cycle to the width of a photosensor being a non-integer. This results in wider bandwidth in a luminance signal. The resulting pickup device output signal comprises a double sideband suppressed carrier signal having subcarriers conveying the chroma information. Both subcarriers can be demodulated, however demodulating only the upper sideband reduces biasing.
