A camera (1) comprises a microprocessor (26) which controls a light projector (35) for projecting a measuring scale (12) having graduations (15) onto two peripheral edges (17 and 18) of a film (3) in an image plane (4). The microprocessor (26) determines the magnification (positive or negative) of an image (2) formed on the film (3) relative to the object from which the image (2) is formed, and the spacing between the graduations (15) corresponds to the number of metric units represented by the spacing between the graduations (15) and the magnification of the image (2) so that when a print is made on photographic paper the linear dimensions of the image in the plane of the …

Why it's free to use
- Filed April 3, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 3, 2020.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
