Patent ID: 8749625

Claim:
A method for resetting a CMOS imaging element in an endoscope apparatus where a CMOS imaging element which takes an endoscope image is provided at a distal end of an insertion portion, the method restoring the CMOS imaging element to a normal state when the CMOS imaging element is out of control, comprising: a first reset step of executing soft reset to initialize a register of the CMOS imaging element; a second reset step of executing device reset to initialize a signal processing section of the CMOS imaging element when the CMOS imaging element is not restored to a normal state by the first reset step; and a third reset step of temporarily stopping power supply to the CMOS imaging element and restarting the power supply when the CMOS imaging element is not restored to a normal state by the second reset step, wherein the endoscope apparatus is connected to a processor apparatus which processes an imaging signal output from the CMOS imaging element and displays an endoscope image on a monitor.
