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 color camera system is disclosed in which a dot-like signal which appears on a TV screen caused by a processing error is effectively eliminated. A pick up device with a color coding filter derives composite signals containing color components modulated at a frequency f.sub.s where the composite signals are obtained in opposite phase line by line. An adder circuit is provided to mix the composite signals obtained from two adjacent lines. A detector detects the 2nd harmonic of f.sub.s from the mixed composite signals. A dual gate MOSFET is provided to suppress a high frequency region of a luminance signal which is derived from the composite signals in response to the detected 2nd harmonic of f.sub.s.

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.
