PURPOSE:To reduce hardwares by performing signal processings for the number smaller than the number of plural imaging device input and allocating gains and signal processing set values for the plural imaging devices from a control circuit to the small number of signal processors. CONSTITUTION:K pieces of the imaging devices 1 are selected from (n) pieces of the imaging devices 1 in a signal selecting circuit 2 and K pieces of output devices 5 are selected from (m) pieces of the output devices 5 in the signal selecting circuit 4 and are connected to K pieces of picture signal processors 3. In the control circuit 6, the gains and the set values, etc., corresponding to the respective (n) pieces of the imaging devices 1 are stored and the imaging devices 1 in use are controlled. Also, signal selecting means 2 and 4 are switched during a blanking period by FV pulses, data corresponding to the imaging devices 1 connected at present are fetched to the control circuit 6, an arithmetic processing is performed inside the control circuit 6, signals from the imaging devices 1 are switched for every 1 field and output is possible even when the output devices 5 more than the number of the picture signal processors 3 are present. |
