Abstract
A color encoding filter is provided for use with a camera having a solid-state imager. The filter comprises a plurality of rows of color filter elements, each row having a sequence of color filter elements which repeats after a predetermined number P of elements, wherein P is greater than or equal to eight (8). Sequential rows of the color filter elements are shifted in the row direction by at least two elements from the preceding row such that the combination of vertically aligned filter elements from adjacent rows provides a sequence of at least two independent color combinations. The color combination sequence repeats after a number of combinations equal to the predetermined number P and has like color combinations symmetrically disposed about one color combination of the color combination sequence. A color signal decoding scheme is also disclosed, which features analog signal processing that makes advantageous use of the color filter symmetry.
