Abstract: This specification describes a scheme for improving the optical resolution of charge coupled device (CCD) shift registers by permitting optical sensing in potential wells under adjacent or closely spaced gates. First one gate in each of the bits of the shift register is energized for optical sensing and the information so sensed is read out of the shift register and stored in memory of some kind. Thereafter, an adjacent or closely spaced gate is energized to sense data optically and this information is read out of the shift register and stored. This is continued until all of the possible gates, or as many as desired, are used for optical sensing. When optical sensing is complete the stored data is reorganized by an interleaving procedure that leaves the data in coherent form.

Abstract: A charge coupled device shift-register optical sensor with storage is provided which is capable of compensating automatically for continuous image exposure. Selected gates of the shift register are pre-disposed for a given time duration to sense the optical image in potential wells under the selected gates. Subsequently, other gates are pre-disposed sequentially to shift the sensed image along the shift register. The recorded image data is regenerated by the regenerating circuitry after a predetermined number of shifts so that the accumulated shift time giving rise to image exposure is less than the exposure time to provide total image sensing, thereby, providing a means for distinguishing between the full duration sensed image data and the image data sensed during shifting as a result of said continuous optical conveying of the image onto the shift register. The storage function is provided by recirculating the data from the output back to the input.
