カメラ。In the recording signal processing circuit of a color video camera with a magnetic recording device that integrates a television camera and a video signal recording device, automatic gain control is applied to the three types of luminance and color signals obtained in the imaging section. The maximum amplitude is controlled to a constant value, and these signals are converted by the matrix circuit of the camera section to obtain the three signals R.k - Y, B = Y, Y], and the required frequency component of the Y signal is Approximately 1.2MH2
An FM modulated signal having a frequency band as described above is used, and the three signals R-Y, B-Y are quadrature two-phase balanced modulated with a carrier wave of an appropriate frequency lower than the FM modulated signal to obtain a chromaticity signal. and the FM modulated signal and the chromaticity signal are mixed in a mixer and recorded on a magnetic recording medium,
Only one GC circuit is provided, and three signals R-Y, B-Y and Y are provided between the matrix circuit and the mixer.
A color video camera characterized by having a signal and an independent configuration.
