主权项

1. An apparatus comprising:
a pixel array including a plurality of pixels; and a filter array positioned over the pixel array, the filter array comprising a plurality of tiled minimal repeating units, each minimal repeating unit including at least four meshed filter sets, wherein each meshed filter set includes a different set of two or more filter wavelengths than any other meshed filter set in the minimal repeating unit such that no two meshed filter sets in the minimal repeating unit share the same set of filter wavelengths, and wherein when placed in the filter array each filter set includes interstitial spaces between its filters to accommodate filters from another filter set.
