摘要： A color television camera apparatus having pick-up tubes provided for three primary color components, process amplifiers and an adjustment control circuit for supplying an amount of the adjustment to compensating circuits in the process amplifiers in response to output signals from the process amplifiers. The process amplifiers contain A/D converters connected to the inputs of the amplifiers, respectively. The process amplifiers and the adjustment control circuit digitally process the signals.

摘要： In a television camera apparatus comprising a camera head, a camera control unit, and a camera cable for transmission of signals between the camera head and the camera control unit, the signals to be transmitted modulate frequency signals corresponding to integral multiples of a reference frequency, and the modulated signals are mixed and transmitted by means of the single-core camera cable. Oscillators to produce reference frequency signals are provided respectively for the camera head and the camera control unit, the oscillator of the camera head being controlled for synchronism by the reference frequency signal of the oscillator of the camera control unit or vice versa.
