摘要： In processing a video signal, vertical correlation is utilized between video signals of successive line intervals. Video signals from the two line intervals are examined, their existences, polarities and magnitudes between them. If both signals exist with the same polarity, a smaller signal in magnitude is derived at a system output and otherwise no signal appears at the output. This system can be applied to a color television camera circuit.

摘要： A solid-state video camera employing a plurality of image sensing means in the form of charge coupled device chips which are arranged in such a manner that the video image cast on respective chips are displaced by distance equal to .tau.H/N where .tau..sub.H is the reciprocal of the image sampling frequency, also referred to as the alignment pitch of the picture elements in the horizontal direction and N is the number of charge coupled chips. After converting the images into electrical signals, read-out timings of given picture elements of respective chips are shifted in time in accordance with the shift in distance between the images on the respective chips prior to mixing the output signals. In this way a video output signal having a wide-band width is obtained. In addition, color video information is possible by the use of color filters which may be disposed in front of the respective charge coupled chips.
