Abstract
An electronic endoscope is provided with a CCD control system which can prevent CCD breakage caused by a latchup, etc. by detecting a Vsub output error and a Vsub supply error without placing any device near the CCD. The endoscope system has a scope including a CCD placed at the scope's distal end, a driving section that supplies a drive signal to a CCD and drives the CCD and a bias voltage generation that generates a substrate bias voltage, a processor, a voltage monitoring section that monitors the voltage value of the substrate bias voltage, a current consumption monitoring section that monitors the current consumption corresponding to the substrate bias voltage, a drive stopping section that stops supplying the drive signal to the CCD when the voltage monitoring section or the current consumption section determines an error occurs.
