Abstract
An endoscope system includes: an electric lens capable of changing a focal length by applying a voltage; an imaging unit configured to capture a subject image formed by the electric lens to generate image signals; a focus controller configured to perform control to periodically repeat sequential switching of the focal length of the electric lens between two or more values; and a video signal generator configured to generate a video signal to be provided to a display device from the image signals generated by the imaging unit.
