Abstract
Abstract The invention discloses techniques suited for extracting image from detected image. First device is a CCD imager having two horizontal CCDs, driven separately, arranged in the vertical direction along vertical CCDs thereof. Further, it has initialize means for releasing all charges in the outer horizontal CCD at once in response to first external signal. First apparatus comprises first device and controller for producing horizontal drive pulses, the number of pulses for the inner horizontal CCD being determined by second external signal. Second device has two CCD imagers driven separately, arranged in main scanning direction, forming one imaging plane. Second apparatus comprises second device; second controller for producing driving pulses at such timing that image signals from these imagers are formed into a one-scan-line image signal which is longer than a horizontal scanning interval, with a variable phase with a horizontal blanking signal; and a switch for transferring these image signals only for horizontal scanning period. The variable phase is determined by third external signal. Third apparatus comprises first or second apparatus wherein the controller further has a circuit for producing vertical transfer pulses wherein high speed transfer pulses are provided before begining of normal transfer pulses. The number of high speed pulses is determined by fourth external signal. Fourth apparatus comprises first, second, or third apparatus and a moving detector for detecting movement of detected images over two fields for canclling the movement on displayed image, which utilizes field correlation and for outputting these external signals.
