Abstract
An endoscope device includes: an imaging unit for photoelectrically converting light from an object that has been irradiated with the light to generate an image signal; an optical signal converter for converting the image signal into an optical signal; a signal dividing unit for dividing the optical signal into first and second optical signals at a predetermined light quantity ratio; a first optical signal transmission line for transmitting the first optical signal; a connecting unit configured to connect the first optical signal transmission line and other optical signal transmission line and to input the first optical signal that has been transmitted through the first optical signal transmission line into the other optical signal transmission line; an electrical signal converter configured to convert the second optical signal into an electrical signal including light quantity information of the second optical signal; and an electrical signal transmission line for transmitting the electrical signal.
