Abstract
Embodiments of an apparatus comprising a pixel array comprising a plurality of macropixels. Each macropixel includes a pair of first pixels each including a color filter for a first color, the first color being one to which pixels are most sensitive, a second pixel including a color filter for a second color, the second color being one to which the pixels are least sensitive and a 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. Corresponding process and system embodiments are disclosed and claimed.
