Color filter array with reference pixel to reduce spectral crosstalk
Abstract:
A color filter array includes a plurality of tiled minimal repeating units, each minimal repeating unit comprising an M×N set of individual filters. Each minimal repeating unit includes a plurality of imaging filters including individual filters having at least first, second, and third photoresponses, and at least one reference filter having a reference photoresponse, wherein the reference filter is positioned among the imaging filters and wherein the reference photoresponse transmits substantially the crosstalk spectrum that is not filtered from light incident on the color filter array by the plurality of imaging filters. Other embodiments are disclosed and claimed.
