Patent ID: 7759752

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 each of the at least first and second photosensitive regions; and (d) a transfer gate associated with each photosensitive region that selectively passes charge to respective 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 of a photosensitive region to be passed to one charge-coupled device, and when the transfer gate is energized at the second voltage level, causes the charge stored in the other depth region of the photosensitive region to be passed to another charge-coupled device.
