Claim:
1. A color filter array comprising: a plurality of first pixels suitable for transmitting light having visible wavelengths; a plurality of second pixels suitable for transmitting light having a first range of wavelengths in the visible spectrum; a plurality of third pixels suitable for transmitting light having a second range of wavelengths in the visible spectrum; and a plurality of crosstalk detection pixels each including a first half pixel and a second half pixel, wherein the first half pixel transmits light having first wavelengths that are within the first range, and the second half pixel transmits light having second wavelengths that are within the second range, and wherein the first half pixel has higher spectral sensitivity correlation to the plurality of second pixels than the plurality of third pixels, and the second half pixel has higher spectral sensitivity correlation to the plurality of third pixels than the plurality of second pixels, wherein the plurality of second pixels have the lowest spectral sensitivity correlation to the plurality of third pixels.
