Patent ID: 7259788

Claim:
An image sensor, comprising: a two-dimensional array of pixel elements, said array of pixel elements outputting pixel data representing an image of a scene; and a two-dimensional array of selectively transmissive filters superimposed on said two-dimensional array of pixel elements, whereby each pixel element in said array of pixel elements is disposed to capture a first and a second color spectra of visible light, wherein said two-dimensional array of selectively transmissive filters comprises a two-dimensional array of filter cells, each filter cell superimposed and in registration with each of said pixel elements, each of said filter cells comprising a selectively transmissive filter of a first type and a selectively transmissive filter of a second type formed as four quadrants in an active area of said filter cell; and in each filter cell, said selectively transmissive filter of said first type occupies a first quadrant and a second quadrant diagonal from said first quadrant.
