ABSTRACT:
An imaging area has a substrate with a mosaic of photo diodes arranged in rows and columns on a solid state substrate. Vertical shift registers are positioned between the columns to transfer photo charges out of the photo diodes and to associated electronic circuits. Depletion layers are interposed in said substrate to separate it into areas. Pulses are applied to the depletion layers driving the transfer periods in order to prevent charge overflow, and therefore a smearing of the image.
