Win Chyi Chang: High resolution charge-coupled device (CCD) camera system. Eastman Kodak Company, Stephen C Kaufman, January 26, 1993: US05182647 (49 worldwide citation)

The present invention is a high resolution charge-coupled device (CCD) camera system having a CCD camera which is capable of operating at a low data rate (e.g., 1 to 2.5 MHz) that is compatible with the input data rate of a computer. An output of the CCD camera is coupled through an analog-to-digita ...

Constantine N Anagnostopoulos, Stephen Lawrence Kosman, Win chyi Chang: Image sensor having ITO electrodes with overlapping color filters for increased sensitivity. Eastman Kodak Company, James D Leimbach, August 25, 1998: US05798542 (9 worldwide citation)

By designing pixels with highly transparent ITO electrodes and asymmetric gates such that as much light as possible falls upon a region covered by an ITO electrode, light sensitivity is increased. Impurity diffusion from the ITO electrode into the silicon below is prevented by employing an Oxide/Nit ...
