ABSTRACT:
A color coding filter is combined with a single area-imaging charge-coupled-device (CCD) to form a color television camera. Three-phase CCD of frame transfer type provides a 2:1 interlace scanning format, and the color filter is designed for compatibility with this format. The filter is formed from a plurality of different color transmissivity areas arranged in a specific grid-like pattern to provide the distinct filter characteristics required for each of the two interlaced fields. With this filtering, the CCD generates a continuous luminance and two line-sequential chrominance (color difference) signals.
