Abstract
Abstract The photographic camera which prints a code signal representing printing information on a film is capable of selecting a real focal length photographing mode for printing a normal range of a frame, a plurality of pseudo focal length photographing mode each being different in pseaudo focal length from the other, and a close-up photographing mode. Exposure condition is limited in accordance with the selected mode. Upon selection of the photographing modes, a code signal indicative of said selection is produced and printed between frames on the film surface. The film after photographing with this camera is subjected to printing by means of a printer which reads the code signal printed on the film surface, determines an exposure value in accordance with the code signal and determines an enlargement ratio.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
A photographic camera having a photographic lens, comprising: means for selecting a real focal length photographing mode in which a normal range in a frame of a film will be printed on a photographic paper and a pseudo focal length photographing mode in which a range smaller than the normal range in a frame of the film will be printed on a photographic paper; means for specifying a magnification corresponding to a range to be printed on the photographic paper in printing when the pseudo focal length photographing mode is selected; means for producing a film sensitivity signal indicative of a sensitivity of the film loaded in the camera; means for discriminating whether the film sensitivity is above a predetermined film sensitivity in accordance with the film sensitivity signal; and means for limiting the magnification capable of being specified by the magnification specifying means below a predetermined value when the film sensitivity is below the predetermined film sensitivity.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
102 words
A photographic camera, comprising: means for selecting one of a plurality of pseudo focal length photographing modes in which a range smaller than a normal range in a frame of the film will be printed on a photographic paper, the plurality of pseudo focal length photographing modes being different in pseudo focal length from each other; means for producing a sensitivity signal indicative of a sensitivity of the film loaded in the camera; and means for limiting the selectable pseudo focal length photographing modes not to be over a predetermined pseudo focal length when the film sensitivity is above a predetermined value.
Claim 4
Dependent Claim
