Abstract

PURPOSE:To drive an AGC circuit even during using an EE lens device by judging whether an image signal reaches a required level or not during using the EE lens device. CONSTITUTION:Since a difference between both ends of a resistance 22 is generated when an EE lens is attached, a voltage comparator 23 outputs a logic ''0'' when the EE lens device is attached and outputs a logic ''1'' when the EE lens device is not attached. A logical OR of this signal and an output signal of an AND circuit 20 is outputted to an OR circuit 24, an analog switch 25 is turned on, and an AGC circuit driving voltage outputted fro an image signal level detecting device 16 is inputted to a process circuit 13. The circuit 13 drives an AGC circuit to amplify an image signal and output. Thereby, a complete image signal can be generated in order to obtain a good image.
