Abstract
An endoscope device includes an imaging optical system including two incident light paths formed by two optical systems respectively having optical axes eccentric with respect to an imaging center of an imaging element, an optical action member configured to change a convergence angle, and a processor configured to control a state of the optical action member in the imaging optical system. The processor changes the convergence angle by controlling the state of the optical action member in the imaging optical system.
