A color filter is provided for use with an imager which has a plurality of discrete collection sites. The filter has a plurality of color filter elements arranged in rows aligned with the collection sites. Two elements of the filter overlay a scan line of the imager in one television field, and each of the rows has a repeating sequence, e.g., 6, of at least two independent colors. The adjacent rows in the filter have their color sequences shifted by two elements. A demultiplexing scheme is disclosed, which features a high-frequency luminance signal having a constant colorimetric composition.

A camera, comprising: a solid-state imager having a plurality of collection sites arranged in rows for collecting fields of unprocessed signals generated in response to received radiant energy from a scene; a color filter, interposed between said scene and said imager, having color filter elements arranged in rows and columns, a pair of said rows of said color filter elements, during a given field, being instantaneously aligned with a row of said collection sites, each of said rows of said color filter elements comprising a repeating sequence of colors, sequential rows of said color filter elements being shifted in the row direction with respect to the preceding row; the combination of vertically aligned filter elements from sequential rows providing at least two independent color combinations; and signal processing means, coupled to said imager, for generating a processed signal representative of said scene, including information related to the color content of said scene.
