A technique for producing electronic video signals representative of color images of a scene includes use of a regular CCD for the color channel and a back-thinned CCD for a luminance channel; a technique for deriving blue and reconstructing full resolution R, G, B from full resolution white and a red and green checkerboard pattern; and a technique for deriving an automatic gain control signal using an unshielded white area on the CCD to obtain a white reference.

No. 6,891,568,(which claims priority from U.S. Provisional Patent Application No. 60/151,965, filed Sep. 1, 1999 and from U.S. Provisional Patent Application No. 60/171,361, filed Dec. 22, 1999). The present Application also claims priority from the following three U.S. Provisional Patent Applications, which are incorporated herein by reference: U.S. Provisional Patent Application No. 60/232,945, filed Sep. 15, 2000; U.S. Provisional Patent Application No. 60,232,947, filed Sep. 15, 2000; U.S. Provisional Patent Application No. 60/314,209, filed Aug. 22, 2001.
Method and apparatus for generating an output signal that represents light with a desired color profile. A first sensor is provided to receive light and based thereon to generate a first signal with a first color profile. A color sensor is also provided that receives light and based thereon generates a second signal with a second color profile. A signal generation mechanism that is coupled to the first sensor and the color sensor and receives the first signal with a first color profile, receives the second signal with a second color profile, and performs a predetermined operation on the first signal and the second signal to generate the output signal with the desired color profile.
