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 photographic paper can readily be read directly from the measuring scales which are formed on the photograph which correspond to the measuring scales (12). The dimensions read from the measuring scale (12) are the actual dimensions of the object.
Un appareil photographique (1) comprend un microprocesseur (26) qui commande un projecteur (35) en vue de projeter une échelle de mesure (12) comportant des graduations (15) sur deux bords périphériques (17 et 18) d'un film (3) dans un plan d'image (4). Le microprocesseur (26) détermine le grossissement (positif ou négatif) d'une image (2) formée sur le film (3) par rapport à l'objet à partir duquel est formée l'image (2) ; et l'espacement des graduations (15) correspond au nombre d'unités métriques représenté par l'espacement des graduations (15) et le grossissement de l'image (2), de sorte que lorsqu'on forme une impression sur papier photographique, les dimensions linéaires de l'image dans le plan du papier photographique peuvent être lues facilement, directement à partir des échelles de mesure formées sur la photographie, qui correspondent aux échelles de mesure (12). Les dimensions lues sur l'échelle de mesure (12) sont les dimensions réelles de l'objet.
