Abstract
An endoscope includes an image sensor and a first memory, which is a nonvolatile memory, storing first information disposed in a distal end portion, and includes a controller and a second memory configured to back up the first information disposed on a proximal end side relative to the distal end portion. The controller reads out the first information stored in the first memory and stores the read first information as a backup in the second memory when the controller is started when supplied with power, and reads out the first information stored in the second memory and transmits the read first information to a video processor when the controller receives a request from the video processor.
