Abstract
Color filter for a digital sensor formed of a two-dimensional array of pixels, each pixel corresponding to a given color. The pixels are arranged in at least one base pattern repeated over a given surface, which has at least three pixels of three different colors. The color filter is characterized in that it includes a plurality of distinct base patterns, each of these patterns having predefined optical properties of sensitivity, of color quality and of resolution, and in that it is subdivided into a plurality of distinct areas, each corresponding to a two-dimensional sub-array of pixels. Each of the base patterns is repeated several times along each dimension of the two-dimensional sub-array, respectively over the entirety of a corresponding area.
