Abstract: An exemplary aspect of the invention can provide a method for easily adjusting the distortion of a projected image. In adjusting the amount of distortion correction, values of the amount of distortion correction for a desired outline form to be formed based on desired positions are calculated after the desired positions can be specified.

If all the calculated values of the amount of distortion correction are within the predetermined range, the calculated values of the amount of distortion correction can be set in an image distortion correction part.

Abstract: A lens-fitted photo film unit comprises a main body, a bottom lid, and a photo film. The main body has an exposure chamber with a taking lens. The exposure chamber is provided with a plane mirror disposed in such a manner as to be inclined 45 degrees with respect to the optical axis of the taking lens. Since the plane mirror reflects light from a subject, a photographic optical path of the light is perpendicularly bent. Subject light forms an image on the photo film disposed in parallel with the optical axis. A side print is exposed in the manufacture on the lateral edge of the photo film. Since the orientation of the photographed image is the same as that of the side print, it is possible to easily confirm the orientation of the photographed image in the development and print processes.

Abstract: A method and apparatus or configuration generates light of a given polarization state (P). A polarization state-sensitive beam splitter is acted upon by light (L) at an input (E1), light (LP) of the given polarization state being output by the beam splitter (1) at a first beam splitter output (A1).

The light of the changed polarization state again acts upon the polarization state-sensitive beam splitter at the input (E1). The apparatus or configuration achieves this by having the optic input (E3) of a polarization state-changing structural element whose optic output (A3) is operationally connected to the optic input (E1) of the polarization state-sensitive beam splitter, operationally connected to the second optic output (A2).
