Abstract

Charge-Coupled Device (CCD) area image detectors of the interline-transfer type include a design feature which enables analog image data to be electrically inserted into the vertical registers via a horizontal input register and, when the device is adequately cooled, this data can be temporarily stored in the vertical registers. Such analog storage devices have been successfully used in several R & D programs performing functions such as TV scan rate reduction, background cancellation in chopper operated pyroelectric vidicons and precision TV field delay for image processing. The results from these programs, consolidated with other CCD technology advances, form the basis for a new program now in progress at Fairchild Camera and Instrument Corp. sponsored by the Night Vision and E Ilectro Optical Laboratory. This program has as its objective the development of an Analog TV Scan Rate Converter and its primary storage element, a two-dimensional analog storage charge-coupled device containing 640 X 256 storage sites. The scan rate converter is intended to interface with TV data compression systems and other systems which require a large two-dimensional analog memory plane. This paper describes the Analog TV Scan Rate converter and the storage CCD under development. The current status of analog image storage using charge-coupled devices is reviewed and potential applications are explored.
