Claim:
An apparatus comprising: a pixel array comprising a plurality of quadrilateral macropixels formed on a substrate, each macropixel including four pixels, wherein the four pixels include: a pair of first pixels in opposite corners, wherein each of the first pixels includes a color filter for a first color, the first color being one to which pixels are most sensitive, and a second pixel and a third pixel in opposite corners, wherein: the second pixel includes a color filter for a second color, the second color being one to which the pixels are least sensitive, and the third pixel including a color filter for a third color, the third color being one to which pixels have a sensitivity between the least sensitive and the most sensitive, wherein the first pixels each occupy a greater proportion of the light-collection area of the macropixel than either the second pixel or the third pixel, such that the first pixels each occupy substantially between 20 percent and 40 percent of the light-collection area of the macropixel, the second pixel occupies substantially between 10 percent and 20 percent of the light-collection area of the macro pixel, and the third pixel occupies substantially between 10 percent and 20 percent of the light collection area of the macro pixel.
