Patent Images

1. An electronic endoscope, comprising:

  • an objective lens system which causes chief rays that are directed toward a maximum image height to be inclined outwardly with respect to an optical axis of said objective lens system; and

    a solid-state image sensor having a light-receiving surface on which a plurality of pixels are arrayed, wherein said solid-state image sensor is configured so that each of said plurality of pixels generates a largest power when alight beam is incident thereon with a predetermined outward inclination in reference to the optical axis, and said outward inclination of a light beam that causes the pixel to generate the largest power increases as a position of the pixel on said light-receiving surface separates from a center of said light-receiving surface at least in one direction.
