Abstract
A lens-fitted photo film is pre-loaded with a photo film. Imaging frames are created on the photo film by releasing the shutter. There is aspect ratio information optically prerecorded on the photo film outside of the imaging frames, and associated with a respective one of the imaging frames. The aspect ratio information includes two dots, and represents an aspect ratio in two bits. The imaging frames are printed in accordance with the aspect ratio. The lens-fitted photo film unit has a viewfinder with a view field of the aspect ratio represented by the aspect ratio information.

A method of producing a lens-fitted photo film unit having a body, viewfinder disposed in said body, and a photo film pre-loaded in said body, the lens-fitted photo film unit being adapted to create imaging frames on said photo film through photographic exposure, said producing method comprising a step of:
- for each said imaging frame, optically prerecording a set of only two indicia disposed adjacent to each of said imaging frames, each of the indicia being continuous, each said set of indicia being similarly positioned with respect to a respective said imaging frame, all of said sets of indicia being indicative of a single aspect ratio of photographic print to be made from each of the imaging frames.
A lens-fitted photo film unit having a body, a viewfinder disposed in said body, and photo film pre-loaded in said body, the lens-fitted photo film unit being adapted to create imaging frames on the photo film through photographic exposure;
- wherein the photographic film includes a set of only two optically prerecorded indicia disposed adjacent to each of the imaging frames, the sets of indicia being equal in number to the imaging frames, each of the indicia being continuous, each said set of indicia being similarly positioned with respect to a respective said imaging frame, all of said sets of indicia being indicative of a single aspect ratio of a photographic print to be made from each of the imaging frames.
A method of producing a lens-fitted photo film unit having a body, a viewfinder disposed in said body, and a photo film pre-loaded in said body, the lens-fitted photo film unit being adapted to create imaging frames on the photo film through photographic exposure, said producing method comprising the steps of:
- continuously conveying said photo film;
- and
- for each said imaging frame, optically prerecording aspect ratio information on said photo film adjacent to a respective said imaging frame by driving a light source while said photo film is continuously conveyed, said light source being aimed at an area of said photo film adjacent to a respective said imaging frame to record said indicia photographically, said aspect ratio information including two indicia.
