[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for recording shutter speed, aperture, and other various data at the time of photographing on photographic film.

0002

[Prior Art] As shown in FIG. 4, a photographic film 1
has an engaging hole 2 called a perforation for moving the film 1 when it is attached to the camera.
A large number of holes are formed at equal intervals in the longitudinal direction near the edges on both sides. After development, on the surface of the film 1 coated with the photosensitive material, frames 3, which are areas in which photographed images are displayed, are sequentially arranged with gap areas 4 equally spaced about 2 mm apart. The film 1 is marked with "1", "2", "3", for example, in the edge area 5 between the engagement hole 2 and the outer edge, corresponding to the 1st to 24th frames 3, for example. ,..."24"
In some cases, a serial number 6 indicating the shooting order for one film is written in advance, such as in the following example. This edge area 5
In addition, the manufacturer's mark 7, bar code 8, etc. may also be written. Some cameras have a mechanism that allows the date of shooting to be displayed at the corner of each frame 3 so as to overlap with the image.

0003

[Problems to be Solved by the Invention] Professional and semi-professional photographers may want to know various data (for example, shutter speed, aperture, lens zoom ratio, etc.) for each shot. In other words, conditions such as brightness vary depending on the time and place of shooting, so if you can recognize various data for each shot, you can use it as reference when taking similar shots later, or if you are unable to take a good shot. It can be used as reference material for the next time. However, at present, such various data must be memorized every time a photograph is taken, which is cumbersome and difficult to implement. Also, recording the shooting date in the corner of each frame 3 is convenient for organizing negative film and photographic paper, but I do not like the date to be displayed on negative film or photographic paper. There are some people. Furthermore, "1", "2", ... "24" are written on the film to correspond to each frame 3.
Even if a serial number such as "1" is written in advance, the serial number "1" may not necessarily appear next to the first video.

Furthermore, when many rolls of film are used for shooting in one day or on one trip, even if you try to organize the films in the order in which they were shot, it becomes difficult to organize the films because you do not know the order in which they were shot. It often disappeared.

[0005]

OBJECTS OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to store various photographic data such as the shutter speed, aperture, and lens zoom ratio at the time of photographing in areas other than the frames of the film.
