Abstract

See full text

Color filter array patterns are provided for enhancing an image sensor's light sensitivity while preserving a color accuracy for image signal processing applications. In one example, an image sensor can include a substrate layer containing a first set of photodiodes and a second set of photodiodes, wherein each of the first set of photodiodes is larger than each of the second set of photodiodes; a first color filter array (CFA) covering the first set of photodiodes, wherein the first CFA includes a first set of color filters and a portion of the first set of color filters includes one or more clear filters; a second CFA covering the second set of photodiodes, wherein the second CFA includes a second set of color filters that is different than the first set of color filters; and one or more lenses covering the first CFA and the second CFA.
