Abstract
An endoscope that captures an image of a biological tissue in a body cavity includes: an image sensor configured to capture the image of the biological tissue; an objective lens that simultaneously forms, as captured images, a front-view image of the biological tissue obtained through a front window facing a front side of a light receiving surface of the image sensor and a side-view image of the biological tissue obtained through a side window facing a lateral side as compared with the front window, on the light receiving surface; and an optical element that is provided in at least one of the front window and the side window, and changes a visual field range of at least one of the front-view image and the side-view image by adjusting a deflection characteristic of incident light with a control signal.
