Abstract

PURPOSE:To take a panoramic photograph even by an ordinary camera having the aperture of a usual size by previously exposing both sides of a J135-film excepting the central part in the width direction of the film. CONSTITUTION:As to the J135-film F dedicated to panoramic photography, a belt-like unexposed area A having a width W is left in the central part in the width direction and already exposed areas B where exposure processing is previously performed on a maker side are provided on both sides. Therefore, the film F is loaded in a general camera having the aperture of the usual size or a camera integrated with film, and a photographic image plane P whose width is W and whose length is 36mm is recorded spaced at 2mm image plane intervals on the film F. Since it is immediately discriminated as the panoramic photograph at a glance after development, printing in a panoramic size is performed to the photographed film being the film F dedicated to panoramic photography in a photofinishing laboratory.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film exclusively for panoramic photography and a film-integrated camera incorporating the film exclusively for panoramic photography.

[Background of the invention]

Panoramic photographs, which allow you to see a vast screen at a glance, have long been produced using two methods. One method is to rotate the direction of the camera in the horizontal direction using a normal camera to take multiple photos and produce prints, and the other method is to take a panoramic photo using a dedicated panoramic camera.

Recently, simple panoramic cameras have become available. This is a method of taking panoramic photographs using a film-integrated camera, also known as a disposable camera, which is commercially available and has a built-in film.

With this method using a film-integrated camera, there is no need to rotate the camera when taking pictures, and there is no need to use a dedicated panoramic camera body; the image taken is cropped horizontally and enlarged in the same way as with a general film-integrated camera. By printing, you can obtain panoramic photos extremely easily.

However, as is well known, with film-integrated cameras, processing is requested while the film is still in the camera, so the film shot using the patented camera, which features panoramic photography, is sent to a general full-length processing laboratory at the stage of development. The size (24 x 36 mm) must be clearly distinguishable from film. To this end, by taking pictures with a camera equipped with a panoramic size screen mask for taking panoramic photographs, the images can be easily recognized as panoramic photographs at the photofinishing laboratory after development.

With conventional film-integrated cameras for panoramic photography, the frame advance for each shot is the same as with a normal camera, so although you can use the camera body of a general film-integrated camera, the aperture part is panoramic size. Therefore, despite the small number of cameras, there is a problem in that they must be assembled and managed separately from regular cameras during the production process.

[16th Small Purpose] The present invention solves this problem and improves it by realizing a J135 film that can expose only within the panoramic size screen frame, and by repurposing the main body of a general full-frame camera. The object of the present invention is to provide a film and film integrated camera that enables panoramic photography and recognition in a photo lab.

[Structure of the invention]

The above purpose is to leave the center part of the J135 film in the width direction,
In a film-integrated camera that is characterized by having both sides pre-exposed and in which the film is built in and the light-tight case is disassembled to take out the exposed film after shooting, the film is exposed at both sides while leaving the center part in the width direction. This is accomplished with an integrated film camera, using pre-exposed J135 film and characterized in that the camera has a regular sized aperture.

[Actual travel example]

An embodiment of the invention is shown in FIGS. 1 and 2.

Figure 1 shows the structure of the J1357 Illum F of the present invention and the screen size taken using the film F. The film F, which is used exclusively for panoramic photography, has an unexposed strip of width W in the center of the width direction. Area A is left, and both sides thereof are used as surface light area B, which has been subjected to exposure processing in advance at the manufacturer's side.

This exposure process for the front light area B is usually performed in the process of imprinting frame numbers and bar codes that are previously imprinted on the film.

The film F is loaded into a general camera or a film-integrated camera with a normal size (24 x 36 mm) aperture, and is handled in exactly the same way as a general camera.
The film is wound frame by frame at a pitch of 38 mm, and the unexposed area A is exposed each time.

Therefore, photographic images P having a width W and a lateral length of 36 mm are recorded on the film F with a screen interval of 2 mm, and after development, it can be immediately identified as a panoramic photograph at a glance. Therefore, a film photographed using the above-mentioned panoramic film F will be printed in a panoramic size at a developing laboratory.

Note that the value of the above-mentioned radius W is set to about 13 mm, but considering the screen effect of panoramic photos, etc., it may be set to 10 to 1, for example.
It may be determined within a range of 5 mm.

Figure 2 shows a film-integrated camera loaded with the above-mentioned panoramic film F, in which 1 is a photographing lens;
2 is a viewfinder, 3 is a strobe light emitter, 4 is a switching button, and other main components; 5 is a shirt release plate; 6 is a film counting window; 7 is a film winding knob and other main operating members. .

The camera body of the camera has aperture size,
If you are using the camera body of a normal-sized film-integrated camera that shares all of the above-mentioned components and operating members, etc., and when shipping it as a film-integrated camera for panoramic photography, the front viewfinder 2 A mask plate 2A having a field of view corresponding to a panoramic screen is attached to the screen. This allows the photographer to take a panoramic shot while checking the panoramic shooting range.

Also, it can be used as a shooting lens with a wider angle (e.g. f=25mm).
If you use a lens with a size of about In this case as well, it goes without saying that most of the components of the camera body, operating members, etc. can be used in common.

〔Effect of the invention〕

By providing a J135-y film that can expose only the central part of the film in the width direction, the present invention makes it possible to take panoramic photos even with a normal camera with a normal-sized aperture, and also with a film-integrated camera. If applied to the camera, it will be possible to take panoramic photos using the camera body with a normal-sized aperture and its mechanism as is, and this will allow a film-integrated camera exclusively for panoramic photos to be produced at a low price in response to demand. It became possible to supply

Furthermore, if the present invention is applied to a negative film, since the surface area is black due to development, it is also possible to perform print printing using a trimming mask for normal screens.
