Abstract

A photographic system comprises a camera and a film structure which can be loaded in the camera and in which photographing data can be recorded. The film structure has an image recording section in which a photographed image is recorded and a memory means for storing therein identification data peculiar to the film structure. And the camera inputs the identification data stored in the film structure into the camera and judges according to the inputted identification data whether the film structure is fit for the camera or not. Thereby, the photographing data can be recorded or read only when the film structure is fit for the camera.

Further, the present invention also relates to a film structure which can be loaded in a camera having peculiar identification data so that it is judged whether the film structure is fit for the camera or not.

Claims

1. A camera capable of setting a range of an image to be produced, comprising:

means for setting a range of an image to be produced;

memory means for storing a range limit value, said range limit value capable of being set;

warning means for giving a warning when the image range set by the setting means reached the range limit value stored in the memory means; and

permitting means for permitting the setting of image range beyond the limit range value even when a warning is given by the warning means.

2. A camera as claimed in claim 1, wherein the range limit value stored in the memory means is variable, and the value being different for a monochrome color film than for a color film.

3. A camera as claimed in claim 1, wherein the range limit value stored in the memory means is variable, and the value being different for a negative film than for a positive film.

4. A camera as claimed in claim 1, wherein the range limit value stored in the memory means is variable and in accordance with ISO sensitivity of the film loaded in the camera.

5. A camera as claimed in claim 1, wherein the range limit value stored in the memory means is variable, and the value being different according to manufacturing maker of the film loaded in the camera.
