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 pseudo 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: 3
Claim 1
Independent Claim
134 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 photographing 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 photographing paper; means for measuring light from a predetermined range corresponding to an angle smaller than an angle of view of the photographic lens, the predetermined range being unchangeable irrespective of the selection of the photographing mode and approximately corresponding to a photographing range in an object field when the pseudo focal length photographing mode is selected; and means for controlling exposure of the photographic camera in accordance with the measured result.
Claim 2
Dependent Claim

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 photographing 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 photographing paper; means for measuring light from a predetermined range corresponding to an angle smaller than an angle of view of the photographic lens, the predetermined range being unchangeable irrespective of the selection of the photographing mode and approximately corresponding to a photographing range in an object field when the pseudo focal length photographing mode is selected; and means for controlling exposure of the photographic camera in accordance with the measured result.
Claim 3
Dependent Claim
23 words
A photographic camera as claimed in claim 1, wherein the photographing range of the pseudo focal length photographing mode contains the predetermined range.
