Abstract:
1. An image sensor comprising: (a) at least first and second photosensitive regions; (b) a color filter array having at least two different colors that selectively absorb specific bands of wavelengths of light, and the at least two colors respectively span portions of predetermined photosensitive regions; (c) at least a first charge-coupled device and a second charge-coupled device adjacent the first photosensitive region; (d) at least a third charge-coupled device and a fourth charge-coupled device adjacent the second photosensitive region; (e) at least two transfer gates associated with the first photosensitive region, wherein a first transfer gate selectively passes the charge representing the one color to the first charge-coupled device when energized at one voltage level and a second transfer gate selectively passes the charge representing the different color to the second charge-coupled device when energized at a different voltage level; and (f) at least two transfer gates associated with the second photosensitive region, wherein a third transfer gate selectively passes the charge representing the one color to the third charge-coupled device when energized at one voltage level and a fourth transfer gate selectively passes the charge representing the one color to the fourth charge-coupled device when energized at a different voltage level.
