ABSTRACT:
A CCD control system includes a driving section supplying a drive signal and a power voltage to a CCD, a bias voltage generation section, a monitor signal output section that outputs monitor signals corresponding to the power voltage which is applied to the CCD. The CCD control system further includes a signal switching section that selects a first state where the monitor signals are input/output through the signal switching based on the substrate bias voltage or a second state where the predetermined signal is output. A monitor signal monitoring section is provided to monitor the output from the signal switching section. The monitor signal monitoring section sends a directive signal to the driving section to stop supplying the drive signal when the signal switching section outputs the predetermined signal or when the monitor signal output from the signal switching section in the first state is abnormal.
