PURPOSE:To raise resolution of an important part such as the vicinity of the center part of a picture without narrowing a recording range of a view angle, etc., and to increase an effective information amount which one picture of a film can mediate, by selecting optionally a projection system or distortion characteristics (picture image relation). CONSTITUTION:A titled device is constituted so that sufficient resolution is secured and a room for enlargement can be obtained, even when making a photosensitive film 3 small-sized as an image pickup device is made small-sized. Also, it is made attachable and detachable to and from a conventional image pickup and projection device, etc., by an optical system A of simple constitution. Also, necessity for suppressing forcibly distortion in the optical system A to zero is eliminated, and the degree of freedom of design of a short focus and an optical system of wide-angle lens, etc. is increased. |
