ABSTRACT:
A high sensitivity television camera utilizing storage time control system improves the sensitivity without degradation of resolution. Storage time of signal charge in a CCD image pick-up element which is scanned progressively is controlled. An amount of signal charge stored during the storage time is read out and stored in a pair of frame memories alternately as frame data. A pair of data of adjacent lines stored in the frame memory are read out and delayed by shift registers by 1 clock. Image data are produced from the vertically and horizontally adjacent four pixels which are delayed data and non-delayed data. The image data have a configuration corresponding to the interlace scan.
