RGBC color filter array patterns to minimize color aliasing |
摘要 |
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. |

1. A color filter array comprising:
a plurality of tiled minimal repeating units, each minimal repeating unit including 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; anda 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; wherein:
individual filters in the first set of filters are octagonal; andindividual filters in the second set of filters are quadrilateral, wherein at least two sides of each quadrilateral filter are formed by non-abutting sides of adjacent octagonal filters. |
