BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will now be described in detail with reference to the drawings. As shown in FIG. 1, the configuration of the photography information recording / reproducing apparatus according to the embodiment of the present invention includes an automatic distance measuring section 10 for measuring a subject distance, a brightness photometric section 20 for measuring a subject brightness amount, A switch S1 for turning on / off the release first and second stages, an information storage area selection switch S2, a shooting information reproduction switch S3, a reproduction area setting switch S4, a release switch S5, and a photography information recording / reproducing operation are provided. An operation control unit 30 for controlling,
The operation control unit 30 includes a memory 40 that stores imaging information created by being connected to the output stage of the operation control unit 30 and an information display unit 50 that displays the imaging information to be measured.

The operation of the photography information recording / reproducing apparatus according to the embodiment of the present invention having the above-mentioned structure will be described below with reference to FIGS. 2 and 3. When power is applied to the camera, the operation control unit 30 initializes all the use variables, and then determines whether or not the user can start the shooting operation, and accordingly performs the shooting information recording operation according to the shooting operation. Perform (S110 to S120).

As shown in FIG. 2, when one step of the release switch S1 is operated, the operation control section 30 drives the automatic distance measuring section 10 and the brightness photometric section 20 to measure the subject distance and the brightness amount ( S130).

The operation control unit 30 prepares photographing information such as an aperture value or a shutter driving speed according to the measured object distance and brightness amount, or an operating condition set by the camera itself, and then generates the photographing information. The corresponding information signal is converted and output to the information display unit 50.

The information display unit 50 is driven according to the information signal output from the operation control unit 30 and displays the created current photographing information so that the user can understand it (S14).
0).

When the second stage of the release switch S2 is operated after the current photographing information display operation is performed as described above, the operation control section 30 determines whether or not the photographing information recording area can be selected by the user (S150-). S160). That is, when the release switch S1 is operated in two stages, the information storage position selected by the user is confirmed. For example, when the number of currently used film windings is the third, the operation control unit 30
Stores in the area corresponding to the third film winding number of the memory 40, the film winding number, shooting information such as the aperture value and shutter speed of the current shooting film, and the current shooting completion film number (S160 to S170).

If the user does not select the photographing information recording area, the photographing information and the like in the current photographing are stored in an arbitrary storage area other than the specific area corresponding to the number of used film windings (S180).

After performing the photographing information operation, the operation control unit 3
In 0, the shutter (not shown) is operated according to the shutter driving speed to be created, and photographing is performed (S190).

After the photographing information is recorded as described above, when the user develops and prints the film to be photographed so that the photographing information corresponding to an arbitrary photograph can be known,
The shooting information reproducing operation is performed according to the sequence shown in FIG.

When the information reproducing switch S3 is operated, the operation control unit 30 sets the current mode to the photographing information reproducing mode, and then ignores signal inputs other than the switch input corresponding to the reproducing operation (S210 to S230). . That is, even if a signal from a release switch S1 other than a switch corresponding to reproducing the stored shooting information or a switch operation such as a shooting mode switch is input according to shooting, the operation control unit 30 performs a corresponding shooting operation. do not do.

When the information reproducing switch S3 is operated and the photographing information reproducing mode is set, the operation control unit 30 displays the number of film frames in which the film photographing information is stored through the information display unit 50 (S240).

When the film cartridge numbers are sequentially displayed on the information display section 50, the user operates the reproduction area setting switch S4 to reproduce the film cartridge number to be reproduced. A region is selected (S250).

The operation control section 30 deciphers the photographing information stored in the area of the memory 40 corresponding to the film cartridge number displayed on the information display section 50 in order when the reproduction area setting switch S4 is operated, and then deciphered. The shooting information is output to the information display unit 50.

The information display section 50 sequentially displays shooting information corresponding to the reproduction area set by the user, that is, shooting information such as the selected film cartridge number, the aperture value stored for each film frame, and the shutter speed. (S260). Further, the mode for reproducing the current photographing information can be canceled according to the operation of the cancel switch S5.

[0023]

As described above, according to the embodiment of the present invention,
Film 1 cut (frame) for shooting with the camera
The shooting information for each photo is stored in the memory built into the camera, and the shooting information according to the corresponding film cut (frame) is reproduced and displayed according to the user's need. Can be easily grasped and various more preferable pictures can be taken. In addition, it is possible to solve the inconvenience of the user recording the photographing information of the photograph.
