PURPOSE:To simplify the circuit constitution, by assembling a color pickup section and a recording section in a device main body incorporatedly and making common the handling of signals in a signal transmission system. CONSTITUTION:After a luminance signal Y obtained from a color image sensor 20 is processed with a process processing circuit 21A, a synchronizing signal is superimposed with a synchronizing circuit 22 and applied to the 1st signal synthesis circuit 24 with FM modulation with a frequency modulator 23. On the other hand, a chroma signal C is subjected to a process processing with a process processing circuit 21B and applied to a matrix circuit 25 producing color difference signals to form color difference signals R-G, B-G, which are applied to balanced modulators 26A, 26B. The modulation output signal obtained with the balanced modulation of the balanced modulators 26A, 26B is added and synthesized to the 2nd signal synthesis circuit 28 to obtain a low frequency conversion chroma signal CL. This is applied to the 1st signal synthesis circuit 24 via an LPF29, it is outputted as an image sensing output signal and recorded on a tape 33. |
