Patent ID: 7423681

Claim:
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 two colors respectively span portions of predetermined photosensitive regions; and wherein the at least first and second photosensitive regions are doped so that charge is collected and stored in two separate depth regions of the photosensitive regions; (c) at least two charge-coupled devices adjacent the first photosensitive region; and (d) a first transfer gate associated with the first photosensitive region that selectively passes charge to the at least two charge-coupled devices at first and second voltage levels which, when energized at the first voltage level, causes the charge stored in one depth region to be passed to one of the at least two charge-coupled devices, and when the transfer gate is energized at the second voltage level, causes the charge stored in the other depth region to be passed to one of the at least two charge-coupled devices.
