Abstract

A method of optically exposing photographed data to the surface of a film (3), said data consist of symbolized or digitized indications (8) of the photographed time and date, shutter speed and lens opening etc. The method consists of a step of forming the image of said indications within the imaging frame through the photographic optical system, by lightening said indication with natural light or the light from a specially-provided source or with a part of the self-emitting light of the indication; and a step of exposing said data indication to the side marginal portions (constituting white or black portions) other than the imaging frame with the remaining part of any of said lights. When the image on the film is printed on the photographic paper,the symbolized and digitized data does not appear thereon, and does not obstruct the object image. Since the photographed data are exposed to the side marginal portions of a film, the photographed conditions can be checked at any time with reference thereto, so that the photographed data can be put in order conveniently for future reference.

(Industrial applications)

INDUSTRIAL APPLICABILITY The present invention is used in the field of imaging an image on a film surface, such as a camera and a radiograph.

(Prior art)

The conventional method of imprinting data at the time of taking photographs and radiographs is to prepare a disc in which several types of imprint data such as numbers and symbols are formed in advance on a black board in a white pattern, and humans can use the It is known to turn a number to adjust the number, irradiate it with a lamp, and use the reflected light to expose the surface of the finolem onto which the image of the subject is imprinted, but this requires manual selection of numbers and symbols. And Ϊ) bothersome and error-prone.

For this reason, a digital clock is built into the camera for the shooting date and time, and the value is directly captured. For other shooting data, a light-emitting diode (hereinafter referred to as an LED) lights up in a data shape. A method was used in which data was displayed in a white outline on a liquid crystal display (hereinafter, referred to as LCD), and a lamp was turned on from the rear to copy the data. (These techniques are disclosed, for example, in Japanese Patent Application Laid-Open Nos. 541-118825, 54-136321, and 57-35842. It is described in )

In these methods, the photographed data is stored in the camera Specification

Method of imprinting photographing data on film surface Detailed description of the invention

'' This invention relates to the method of imprinting Peng Peng data on the film surface of Peng Peng, specifically the date and time of Peng Peng, shutter speed, squirrel, use of filters, type of lens, etc. Films of various data (hereinafter referred to as “photographing data”) encoded or converted into numbers (hereinafter referred to as “encoded data”). Films other than the surface on which the subject image is projected. (To be simply referred to as the film side).

J3, wrong] so that it can be confirmed by looking at the display or the finder outside the camera, and the operation is easy. However, in each of these methods, the photographing data is displayed on the surface of the film on which the image of the subject is imprinted. Therefore, if the film is printed on ^! Drawing paper, the symbolized data is displayed on the ^^ surface, and the display is displayed. Often it gets in the way. In particular, when taking photographs that require artistry, photographing data is absolutely necessary, but there is a strong demand for displaying coded data on the photographic surface of the subject. The enlarged image is blurred due to the reduction of the film surface. (The trimming and the like have been removed, and the conventional technology could not meet these demands.)

(The invention is ^: problem to try.)

According to the present invention, when photographing data is transferred as symbolized data on an inolem surface in photographing, the operation is simple and erroneous, and the symbolized data is printed on a film surface. When it is attached, the display of the encoded data can be arbitrarily selected.

Solution to problem C)

According to the present invention, the information recording medium on which the photographing data is recorded is incorporated in the camera, or the light of the separately provided light M is irradiated, or a part of the light emitted by the information recording medium itself reaches the finder. Like that In addition to allowing the photographer to view the encoded data at the same time as the subject image, the light of the remainder]) is transferred to the end of the film other than the surface on which the subject image is projected using various optical systems. This solves the above problem. (See Fig. 5)

(Effect)

According to the present invention, since the photographer can view the so-called symbolized data obtained by symbolizing and digitizing the photographing data and the subject image at any time through the finder, the operation is extremely simple and the operation is extremely simple. In addition, since the encoded data according to the present invention is printed on the film-side end other than the surface on which the subject image of the finolem is printed as shown in FIG. 5, the subject image is not captured when printing. Since it is not harmed by symbols or numbers indicating data, a clear ¾ beautiful ^ A can be printed. In addition, if you look at the negatives of the film, or in some cases, even print the side edges of the huinolem, if you burn it to j ^ sharp, you will get an error as to what the shooting conditions were when the photograph was taken. This is especially useful if you want to clearly artistically capture the whole picture or object image 0-

(Actual 1)

Refer to the drawings for a specific understanding of the present invention. Examples of the method will be described.

FIG. 1 shows a first example of the present invention, and the portion surrounded by the inside is the inside of the camera. (1) is an objective lens, through which light from the outside and inside enters the camera, passes through a reflector (2) to a pentabrhythm (4) as shown by the eye, and passes through an eyepiece ( Through 5), it reaches the photographer's eye (6). Thus, the light from the outside reaches the J? Film (3) unless the shutter is pressed.

On the other hand, an information recording medium for displaying photographed data in symbolized numerical form (eg, a display body such as an LED or an LCD) is supported by a display block (7). These displays': self-generated light or natural light or light emitted by another light source passes through the reflector (9), pen tabrhythm (4), and eyepiece (5) to the photographer's eye (6). At the same time as the object image, the encoded data can be viewed through the τ nders. At this time, the reflector αο) goes up as shown by the solid line in the figure. The light that has exited ventrism (4) goes straight and enters the tangential lens j)? , Up to the photographer's eye (S). Then, when the shutter is pushed, the reflecting mirror (2) and the reflecting mirror (LG) move to the positions indicated by the dotted lines, and the charging through the objective lens goes straight to expose the film (.3) surface. On the other hand, the light from the display (8) passes through the ventrism (4) and then falls down the reflecting mirror (dO). J? (Down to the dotted line in the figure) and is reflected downward as shown in the figure. (The film is reflected again by the LD (3) © To the side edge] 5 i '.....-"Sensitive. The image of the subject is the same as before.]? In front of the film

It is imprinted in the center, and the encoded data is the surface on which the subject image is imprinted.

It is imprinted on the film side edge adjacent to it.

The film imprinted in this way is, for example, developed

Then it looks like Figure 5. Fig. 5 shows the subject image.

The i5 and () are pierced on both sides of the film (3).

FIG. 2 shows another embodiment, which is used as an information recording medium.

T: By illuminating the ^ .π 'graphic diffraction system with light such as reproduction light

O Encoded data information It is of the type that is imprinted on. Figures 3 and 4 are explanatory diagrams of the holographic diffraction system. · ：

In FIG. 2, the symbol ^ in FIG. 2 is an objective lens, and a diffraction system that uses a filter, which is freely rotatable in the optical path, as a holding member is provided behind the objective lens. The output light from the camera or the object image on the film surface through the 'optical fiber' ...:.

- led Phil fu ^ end in contact therewith except Subesu Imprint, marks and A such 〇 or _{A, B, C N D,} E, F, l, 2,肆字such as 3 are imprinted . The presence or absence of the filter, or the type of filter, etc., is printed on the Finolem surface using these marks, symbols, and numbers. This diffraction system (23 passes the light guided into the camera through the objective lens and reaches the reflector C¾. The reflected light is focused on the reticle G.) Through the finder lens ¾ as shown by the solid line in the figure.

A diffraction system can be provided as shown in the figure by using the surface of -reflection 鐽 ^. For example, the diffraction system carries information about the type of lens, etc., and the diffracted light repeats internal reflection and is guided to the upper end of the diffraction system ^. It is guided to the upper end adjacent to the space other than the space where the subject image is projected, and the encoded data is projected. S ″ ·;--· ::-The diffraction system ^ may be of a planar diffraction grating structure or may be 'positive'.

One of the negative order diffraction light is on the film surface and the other is a finder system.

The reticle can be guided so that it can be used for both printing on the film surface and observation with a finder. like this

Figure 5 shows the huinolem with the encoded data imprinted on it.

示す As shown, you can burn the necessary parts.

Here, the principle of displaying symbols and numbers by the diffraction system is explained.

Do it. Symbols and numbers used in the second example

The desired information to the output light of the directional diffraction wave

A diffraction system that outputs a diffracted wave with directivity

The most suitable ones are those with a trapezoidal diffraction grating.

Diffraction systems use the light of coherent strain to create a three-dimensional structure

It can be easily produced as a hologram that can be recorded.

Regarding this, Japanese Patent Application Laid-Open No.

This is explained in detail with reference to 745. Like this

Fig. 3 shows the cross-section of the structural interference record.

A number of boards with a slight width are arranged in order so that the inclination is different.

Is equivalent to a diffraction grating ^

Light, for example, plane wave light, is reflected on each inclined surface to form a real image.

It converges on the focal plane (42). This convergence depends on the diffraction order.

Although the positions are different, it is as if the incident light and Like a relationship! Outgoing light can also be divergent depending on the inclination of each of the constituent surfaces. Fig. 4 shows two three-dimensional diffraction gratings with different characteristics (a transparent flat plate supporting ^^ (provided on the ^ surface, and condensed at two different points depending on each grating by light input from the same light source ^). In this figure, light input from one side of the plate ^ is output from the opposite side, but depending on the structure of the grid, input from one side is shown. The reflected light is reflected from the same surface after diffraction, or the light power input from one surface of the plate; the total reflection is repeated inside the plate as after the diffraction and output from the side end surface Can also.

Therefore, when a hologram having a required information element carried thereon is used as such a grating, it is possible to reproduce the information image at a specific position by giving input light to the hologram. In this case, the hologram is prepared by placing a dry plate with a volimizer sensitive material or other suitable sensitive material at the position of the grid in Fig. 3 or 4, and placing an information source or information recording medium at the position of the bin surface. It is made by providing illumination with coherent light, guiding the light to the surface of the photosensitive material, and irradiating it with coherent reference light. The direction of the output light and the like of the reproduced information image from the frontal gram is determined by the characteristics of the light to be applied when producing the hologram, the operating position, the operating angle, and the like. / β--, the required output light is generated, and the conditions for creating the hologram can be obtained in a wide variety of ways.

Desired information can be used by selection. Drawing tube description '.
