Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method of imprinting photographic data on a film surface in photography and a film used therefor. Aperture, whether to use a filter, type of lens, etc., and for medical photography, various data such as patient name, gender, age, left or right side of the body, location of the affected area, disease name, date of photography, number of times of photography, etc. (see below) (hereinafter referred to as "symbolized data, etc.") may be written as characters or encoded into symbols or numbers (hereinafter referred to as "symbolized data, etc.") at the edge of the film other than the space where the subject image is imprinted (margins or areas that are completely black). This relates to a method for exposing and imprinting on the side edge of the film (hereinafter simply referred to as the film side edge) and the film used therein, and is useful for not only ordinary photography but also medical photography such as X-ray photography, tooth profile photography, gastrocamera, etc., and slides. Also available.

(Prior technology) The conventional method of imprinting data during photography or X-ray photography is to prepare a disk on which several kinds of data such as numbers and symbols are imprinted in outline on a blackboard, and then a person turns a dial from the outside. There is a known method in which the numbers are matched using a lamp, and the reflected light is used to expose the surface of the film on which the subject image is projected, but this method requires manual selection of numbers and symbols. It was cumbersome and error-prone.

Therefore, to determine the date and time of a photograph, a digital clock is built into the camera and the numerical value is recorded directly, and for other photographic data, a light emitting diode (hereinafter referred to as LED) is lit in a data shape and the photograph is recorded. Displayed in white on a liquid crystal display (hereinafter referred to as LCD),
One method used was to light a lamp from behind and capture the image.

(These technologies are disclosed, for example, in Japanese Patent Application Laid-Open No. 5
Publication No. 4-118825, Japanese Unexamined Patent Publication No. 136321/1982
In these methods, the photographer can check the shooting data by looking at the external display or viewfinder of the camera immediately before shooting. , there are no errors, and it is easy to operate.

However, in all of these methods, the photographic data is displayed on the surface of the film where the subject image is imprinted, so-called double talk light, so when the film is printed onto photographic paper, the encoded data does not represent the subject image. The numbers and symbols are displayed on the photographic surface, and the numbers and symbols often overlap with the subject image and are difficult to see, or the display often gets in the way of the subject image. In particular, when taking photographs that require artistic quality, photographic data is absolutely necessary, but there is a strong demand for not displaying encoded data on the surface of the photograph depicting the subject. Therefore, the areas on which these encoded data are imprinted have been deleted by trimming, etc., but with this method, the film surface is reduced by the amount of deletion, and the enlargement magnification must be increased, resulting in blurring of the enlarged image. Therefore, conventional techniques have not been able to fully meet these demands.

(Problems to be Solved) The present invention provides that when photographing data is imprinted on the film surface as encoded data, there is no effect on the subject image photographed on the film, and the side edges of the film are The problem that needs to be solved is to develop a photographic method and film that will allow the image to be captured without overlapping the manufacturer's name or film name stamped on the part.

(Means for solving the problem) In order to solve the above problem, in the first invention,
The photographer uses natural light that enters through the camera lens or other light sources, or even part of the light emitted by the display body itself, to reach the viewfinder, which consists of characters, symbols, numbers, etc. that represent the photographic data, and allows the photographer to visualize the subject image. At the same time, the encoded data can be viewed, and the remaining light is used to capture the image of the object on the film λ using various optical systems. It is guided to the unmarked side edge portion and exposes encoded data to that portion.

In the second aspect of the present invention, in order to enable the above-mentioned photographic data imprinting method, at least one side edge of the film other than the space in which the subject image is imprinted is not printed or exposed. The encoded data is exposed and exposed to light at any position.

(Effect) In the first invention, photographic data can be converted into characters as they are,
Either so-called encoded data that is encoded or digitized is displayed on the display from the outside through an optical fiber, or the encoded data selected by the character, symbol, and number selection device built into the display itself is displayed using natural light or a separately provided light source. The light is directed to the area on the side of the film where nothing is printed or exposed other than the space where the subject image is captured, and is exposed. Therefore, characters, numbers, and symbols of the shooting data can be arbitrarily input from outside. The display can be displayed through an optical fiber, and the built-in character, numerical, and symbol selection device can be easily displayed by simply operating the button outside the frame of the optical imaging device. It is convenient and accurate.Also, an effect common to the first and second inventions is that in the first invention, the photographic data is printed or exposed to nothing other than the space in which the subject image is photographed. Since the image of the subject is not obstructed by the photographic data, the film can be used to a large extent, and the photographic data is not double exposed, so it is easy to see, there are no errors, and the fine grain of the film is eliminated. This makes it possible to make the characters, numbers, and symbols of the photographed data more detailed, allowing a large amount of information to be captured.

Furthermore, when printing the photographed film onto photographic paper, the photographic data can be printed together with the subject image, or it can be removed.

Therefore, by using the method and film of the present invention, it is not necessary to record the photographic data in a notebook or separate table every time a frame is taken, which is convenient and eliminates errors, which is particularly useful in medical photography. .

(Example-1 of the first invention) An embodiment of the first invention will be described with reference to the drawings.

What is shown in FIG. 1 shows the first example of the first invention,
The area surrounded by solid lines is the inside of the camera. (1) is the objective lens, through which light from the outside enters the camera, reaches the reflector (2), passes through the pentaprism (4) as shown by the solid line, and goes to the eyepiece (5) and viewfinder. The image reaches the photographer's eye (6).

In this way, light from outside will not reach the film (3) unless the shutter is pressed.

On the other hand, an information recording medium for displaying photographed data in symbols and numerical form, such as a display body (such as an LED or LCD) (
8) is supported by the display block (7). The light emitted by these display bodies or the light irradiated by natural light or another light source is reflected by a reflecting mirror (9) or a pentaprism (4).
, an eyepiece (5) and a finder θQ to reach the photographer's eye (6), and the encoded data can be seen through the finder 00 at the same time as the subject image. At this time, the reflecting mirror tt[1 is rising upward (as shown by the solid line in the figure).
The light that exits the pentaprism (4) goes straight to the eyepiece (
5) and reaches the photographer's eye (6). After that, when the shutter is pressed, the reflecting mirror (2) and the reflecting mirror (lot) move to the position indicated by the dotted line, and the light passing through the objective lens travels straight to the film (3) surface and is exposed to light. (8)
After passing through the pentaprism (4), the light from
) is reflected (descending to the position indicated by the dotted line in the figure),
As shown in the figure, it is reflected downward and reflected again by the reflecting mirror (Ill) to reach the side edge of the film (3) and is exposed to light.In this way, the subject image is imprinted on the front center of the film as before, and the encoded data is The subject image is imprinted on the side edge of the film adjacent to the imprinted chamfer.In addition, the light from the reflection plate (10) is reflected on the reflection plates (11') and (12).
X12°) may be guided to the back surface of the film as indicated by the dotted line α.

For example, the film imprinted in this way is
When developed, it will look like Figure 6. (51
) is the part where the subject image is imprinted, (52) is the hole (perforation) for raising the film %4 made at both ends of the film (3), and (513) to
(57) is encoded data imprinted on the side edge of the film, (53) indicates the date and time of photographing, and (54) indicates the focal length of the objective lens. (55) is the aperture, (I)
indicates the type of filter, and (57) indicates the shutter speed. In addition, if necessary, the photographic data can be encoded and imprinted on the side edge of the film (3).
Only the necessary encoded data can be printed on photographic paper without affecting the surface on which the subject image is imprinted.

As a means of displaying photographic data on a display body using letters, numbers, and symbols, we have described a method using LOD+LED, but in addition to this, there is also a method using a VDT (terminal display device) connected to a word processor or computer external to the optical photographing device. ) Other characters or symbols may be displayed by being transmitted through an optical fiber from a screen, board, or paper surface.

Note that QΦ in FIG. 1 is a gripping and winding device for OS4 film.

For details on how to change the display symbols and numbers on LCDs and LEDs, please refer to Japanese Patent Application Laid-Open No. 57-6 published by the Japan Patent Office.
Since it is explained in detail in Publication No. 31, it will be omitted here.

(Embodiment 2 of the first invention) FIG. 2 shows another embodiment of the first invention,
By illuminating a holographic diffraction system as a display body with light such as reproduction light, a reproduced image of encoded data information is imprinted onto the film surface by a photographing optical system.

Note that FIG. 3.4 is an explanatory diagram of the holographic diffraction system.

To explain it with a diagram, reference numeral (1) in Fig. 2 is an objective lens, and a diffraction system (23) that uses a filter (23) as a holder is provided behind the objective lens and can be freely inserted into the optical path.
2), and the output light from this diffraction system (22) is guided through the optical fiber (32) to the side edge of the film adjacent to the space other than the space where the subject image is projected on the surface of the film (5). Marks such as A, B, 0, D, E, etc.
Numbers such as F, l, 2.6, etc. are imprinted. These marks, symbols, and numbers are used to identify the chassis tar and bead pavers.
Also, 1st, sharp spots etc. are imprinted on the film surface. This diffraction system @) allows the light guided into the camera through the objective lens to pass through and reach the reflecting mirror (25). The reflected light passes through the focusing plate (27) and the pentaprism (29).
), which passes through the finder lens (3) and reaches the photographer's eye (31) as shown by the solid line in the figure.

On the other hand, using the surface of the reflecting mirror (25), the diffraction system (
24) may also be provided. This diffraction system (24) carries information regarding, for example, the type of objective lens, etc.
The resulting diffracted light undergoes internal reflection repeatedly to form a diffraction system (24)
The output light from the end surface of the film (2) is guided to the upper end of the film (2) adjacent to the space other than the space in which the subject image is to be imaged, and the encoded data is imprinted thereon. In this case, the diffraction system (24) may have a planar diffraction grating structure, or the positive and negative orders of diffracted light may be directed to the film surface on one side and a finder system on the other. It can be guided to a focus plate (27), and can be used for both imprinting on the film surface and observation with a finder. When the film on which the encoded data has been imprinted in this manner is developed, it becomes flat as shown in FIG. 6, and the necessary portions can be printed.

Here, the principle of displaying symbols, numbers, etc. using a diffraction system will be explained. The means for displaying symbols and numbers used in this example is one that imprints desired information on the film surface using the output light of directional diffraction waves, and is the most suitable as a diffraction system that outputs directional diffraction waves. A suitable system is one having a diffraction grating with a three-dimensional structure, and such a diffraction system can easily produce coherent light as a hologram from which interference recording of the three-dimensional structure can be obtained using a polymer sensitive material. This is explained in detail in Japanese Patent Application Laid-open Nos. 46-7390 and 47-5745 published by the Japan Patent Office. Interferometric recording of such a three-dimensional structure can be modeled using a diffraction grating (a diffraction grating ( 41), and the light input thereto, for example, plane wave light (42), is reflected on each inclined surface and converged on a real image focus surface (43). This convergence is
The position differs depending on the order of diffraction, but the relationship is similar to the relationship between the incident light and the outgoing light in a lens, and depending on the inclination of each component surface, the outgoing light can become diverging light. Figure 4 shows two three-dimensional diffraction gratings with different characteristics.
(45) is provided on the surface of a transparent flat plate (46) serving as a support, and light input from the same light source (47) is focused on two different points by each grating. This figure shows a relationship in which light input from one surface of the plate (4f3) is output from the opposite surface, but depending on the configuration of the grating, light input from one surface may be diffracted and then reflected from the diffraction surface. Alternatively, the light input from one side of the plate can be diffracted and then totally reflected by the plate wall as shown in (48), and then output from the side end face.

Therefore, if a hologram carrying a required information element is used as such a grating, the information image can be reproduced at a specific position by applying input light to the hologram. To create a hologram in this case, place a dry plate with a polymer sensitive material or other suitable sensitive material at the grating position shown in Figures 3 or 4, and place an information source or information recording medium at the focal plane. Strengthen the illumination of light,
It is produced by guiding the light to the surface of the sensitive material and irradiating it with coherent reference light. The reproduced information image from this hologram, the direction of the output light, etc. are determined by the characteristics, position, angle, etc. of the light that acts on the information given when making the hologram, and by applying input light that meets the conditions to the hologram. The required output light is generated, and a wide variety of conditions can be determined when creating the hologram, and desired information can be used by selecting the conditions.

(Embodiment of the second invention) The second invention is explained with reference to FIGS. 5 and 6. The film shown in FIG. The name (71) and film number (72) are printed or exposed in advance. Figure 5 and Figure 6 1. What is shown in Figures 5 and 6 is a film according to the present invention.
The figure shows the state before photographing, and FIG. 6 shows the state after photographing. In Figure 5, the company name (63), film number (example), etc. are printed or exposed on the upper edge of the film (61), but nothing is printed or exposed on the lower edge (f32). do not have. Figure 6 shows the film after photographing, in addition to the subject image (51), the lower end of the film (62
), shooting date and time (53), focal length (54), aperture l') (
55), the type of filter (515), the shutter speed, etc., are expressed in text, symbols, and numbers as they are when exposed to light.

These encoded data may be characters or numbers such as "aperture 8", "focal length 5", "filter blue", etc., or "f/8", "F5", "Ft!B"["84°6 .2D
It may be symbolized as J or the like and exposed to light.

Incidentally, in the present invention, the side edges of the film include not only the longitudinal side edges of the film, but also the "frames 1" formed between the imprinted subject images.
