Abstract

An image sensor includes at least first and second photo-sensitive regions; a color filter array having at least two different colors that selectively absorb specific bands of wavelengths, and the two colors respectively span portions of predetermined photo-sensitive regions; and wherein the two photo sensitive regions are doped so that electrons that are released at two different depths in the substrate are collected in two separate regions of the photo sensitive regions so that, when wavelengths of light pass through the color filter array, light is absorbed by the photo sensitive regions which photo sensitive regions consequently releases electrons at two different depths of the photo sensitive regions and are stored in first and second separate regions; at least two charge-coupled devices adjacent the first photo sensitive regions; and a first transfer gate associated with the first photo sensitive region that selectively passes charge at first and second levels which, when at the first level, causes the charge stored in the first region to be passed to one of its associated charge-coupled devices, and when the transfer gate is at the second level, charge stored in the second region is passed to one of the associated charge-coupled devices.

Claims (6)

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 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.
