Abstract:
Implementations of a color filter array comprising a plurality of tiled minimal repeating units. Each minimal repeating unit includes at least a first set of filters comprising three or more color filters, the first set including at least one color filter with a first spectral photoresponse, at least one color filter with a second spectral photoresponse, and at least one color filter with a third spectral photoresponse; and a second set of filters comprising one or more broadband filters positioned among the color filters of the first set, wherein each of the one or more broadband filters has a fourth spectral photoresponse with a broader spectrum than any of the first, second, and third spectral photoresponses, and wherein the individual filters of the second set have a smaller area than any of the individual filters in the first set. Other implementations are disclosed and claimed.
