Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame with a lenticular lens for a photograph in which an image is formed by image exposure through the lenticular lens.

[0002]

2. Description of the Related Art Conventionally, a three-dimensional photograph using a lenticular lens has been known and is manufactured as follows.

That is, first, an image of a subject such as a landscape or a person is photographed a plurality of times while moving the camera in the horizontal direction by a predetermined distance, whereby a series of a plurality of negatives is produced. Further, as disclosed in Japanese Patent Application Laid-Open No. 2-293733, negatives are produced by arranging planar images at perspective positions and changing the position of the arranged image groups and photographing the images plural times with a camera. .
Further, it is also possible to take a picture by using a camera for stereoscopic photography having a plurality of lenses arranged side by side in the horizontal direction. Next, using this negative, image exposure is performed on the printing material using the lenticular lens by the negative.

As shown in FIG. 5, a conventional printing material 80 is used.
On the lower surface of the lenticular lens 81.
It is configured by bonding 2 with an adhesive. The photosensitive film 82 has a photographic emulsion layer 82b formed on the surface of a transparent film 82a.
The surface on the side where 2b is formed is the photosensitive surface. Also, although expensive, it has been proposed to directly apply a photographic emulsion to the lower surface of the lenticular lens 81 to form a photosensitive surface.

For the printing material 80 shown in FIG. 5, the series of negatives described above are used so that strip-shaped images compressed by the respective lenses are continuously formed on the photosensitive surface below the lenticular lens 81. Image exposure is performed by changing the position of the negative and the printing material 80 in the parallel direction by a constant distance. The printing material 80 that has undergone image exposure is developed and fixed.

[0006]

As described above, conventionally, the printing material 80 in which the lenticular lens 81 and the photosensitive film 82 are integrated is used.
Therefore, in order to enable the development of the printing material 80, it is necessary to expose the photographic emulsion layer 82b, which is the photosensitive surface, to the outer surface, and the photographic emulsion layer 82b is located on the side opposite to the lenticular lens 81 side. Will be done. Therefore, an interval corresponding to the thickness of the transparent film 82a is opened between the photosensitive surface and the lenticular lens 81, and the image projected on the photographic emulsion layer 82b is blurred. Therefore, there is a problem that the obtained photograph becomes unclear.

Further, since the structure of the printing material 80 is special, a general-purpose photographic film cannot be used to obtain the photographic material. Further, a general-purpose developing device cannot be used, and a special dedicated device is required. Therefore, the manufacturing cost of this type of photography is increased.

In order to solve such a problem, in the present application, it is possible to prevent a gap from being left between the photosensitive surface and the lenticular lens, and to provide a general-purpose photographic film and a general-purpose developing device. The photographs that can be used and the manufacturing method thereof were separately proposed.

It is an object of the present invention to provide a frame with a lenticular lens, which is low cost and which is preferably used for viewing the separately proposed photograph.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of a photograph 1A according to the present invention, FIG. 2 is an enlarged sectional side view showing a part of the photograph 1A, and FIG. 3 is a photograph material 22 of the photograph 1A of FIG. It is a cross-sectional front view which cuts at a surface position and shows a part thereof.

In these figures, the photograph 1A is composed of a front panel 21, a photographic material 22, and a back panel 23. The front panel 21 is a plate-shaped member formed by molding a transparent synthetic resin material, a lenticular lens 211 is provided in a central rectangular area, a translucent or opaque frame-like portion 212 is provided around the lenticular lens 211, and a peripheral edge is provided at the periphery. A chamfer 213 is provided. Cylindrical protrusions 214a to 214d are provided at four positions on the back surface of the frame-shaped portion 212. The diameters of the three protrusions 214b to 214d are the same as each other, and the diameter of the protrusion 214a is slightly larger than them. As a result, the photographic material 22 is mounted at the same position. In order to make the frame-like portion 212 translucent or opaque, the surface panel 21 is formed with satin or the like, or ink or paint of an appropriate color is printed after the formation, or an opaque sheet is formed on the surface of the front panel 21. Paste. Frame portion 21
No. 2 is preferable because it does not have diffuse reflection so that the photograph can be easily seen, and the photograph looks beautiful and clear. As a result, the front panel 21 is the lenticular lens 211 for observing the image formed on the photographic material 22, and
It also serves as a frame.

The front panel 21 is manufactured by injection molding, but it may be manufactured by another method, for example, casting a transparent synthetic resin plate or performing roll pressing. Machining may be performed if necessary.

The photographic material 22 is formed by coating a photographic emulsion layer 222 on the surface of a transparent film 221 made of, for example, PET (polyethylene terephthalate). The photographic emulsion layer 222 is exposed to an image and then developed. It is being fixed. The outer dimensions of the photographic material 22 are the front panel 21.
Of the lenticular lens 211, and is slightly larger than the outer shape of the lenticular lens 211. As the photographic material 22, for example, a commercially available 4 × 5 photographic film can be used.

The photographic material 22 is provided with holes 223a and 223b at positions corresponding to the protrusions 214a and 214b. One of the holes 223a is a circular hole having substantially the same diameter as the protrusion 214a, and the other one hole 223b is a hole of the protrusion 214a.
It is an elongated hole having the same width dimension as the diameter of b. Therefore, the photographic material 22 is
The positioning is performed by fitting the holes 4a and 4b into the holes 223a and b, and when the projections 214b slide in the holes 223b when they expand or contract due to temperature change, distortion of the photographic material 22 such as twisting. It is prevented from occurring. The holes 223a and 223b are opened using a suitable puncher.

The back panel 23 is made of a transparent soft acrylic plate and has the same outer dimensions as the front panel 21. The back panel 23 has holes 23 at positions corresponding to the protrusions 214a to 214d.
1a-d are provided. The holes 231a to 231 are the protrusions 2
14a to 14d are fitted so that they are in a slightly tight fit. The back panel 23 prevents the photographic material 22 from separating from the front panel 21, and allows the illumination light to pass through from the back surface of the photographic material 22.

In the free state, the back panel 23 of this example is curved so that the central portion thereof is convex toward the side of the photographic material 22. It becomes a straight plane. As a result, the elasticity of the back panel 23 causes the photographic material 22 to move to the front panel 21.
Since it is pressed to the side of, the degree of adhesion between the front panel 21 and the photographic material 22 is improved. However, the back panel 23 in a straight flat state may be used.

To give an example of the dimensions of Photo 1A, the front panel 21 is 15 cm long, 12 cm wide, and 1.5 mm thick, and the photographic material 22B is 12.5 cm long, 10 cm wide, and 0.1 mm thick.
2 mm, the back panel 23 is 15 cm in length, 12 cm in width, 1.5 mm in thickness, and the diameter of the protrusion 214a is 5 mm.
The diameter of b to d is 4 mm.

In the above-mentioned photograph 1A, the image formed on the photographic material 22 is observed through the lenticular lens 211 by viewing it from the front panel 21 side by holding the illumination light from the back side, for example. In the example shown in FIGS. 2 to 4, for example, an image of continuous movement or movement of a person or an object is formed on the photographic material 22, and the photograph 1A is held by hand in the state shown in FIG. By changing the angle (observation angle) of 1A, a person who views the photograph 1A from the front can see the image of each frame according to the observation angle. When the observation angle is changed, as shown in FIG. 2 , the direction in which the photograph 1A is viewed by both eyes is indicated by the arrow EY1,
It changes like a few. For example, in the case of an image in which golf swings are continuously shot, each frame of the swing can be continuously viewed by changing the images as shown by arrows EY1, EY2, and EY3. That is, although the photograph 1 is a single still photograph, it can be seen as a moving image for a person or as a disassembled photograph.

If an image for stereoscopic photography is formed on the photographic material 22, the stereoscopic photography is observed.
However, in that case, the direction of the lenticular lens 211 may be vertical rather than horizontal. In addition,
The illumination light may be obtained from the back side of Photo 1A.

Next, a method of manufacturing the photograph 1A will be described. 1 to 3, the photographic material 22 is image-exposed by a known method in a state where the photographic material 22 before image exposure is mounted on the front panel 21. At that time, for example, the photographic material 22 is set so as to be in close contact with the base of the exposure apparatus, and the front panel 21 is in close contact with the photographic material 22.
A hole is provided in the base, and the protrusions 214a of the front panel 21
Positioning can be performed by inserting d. The chamfered portion 213 of the front panel 21 may be used and fixed by using a stopper that is pushed out horizontally from the side toward the chamfered portion 213. Further, in order to increase the degree of adhesion between the front panel 21 and the photographic material 22, the front panel 21 may be sucked toward the base side by using a vacuum pump.

After the image exposure is completed, the photographic material 22 is separated from the front panel 21 and developed and fixed. afterwards,
The imaged photographic material 22 is remounted on the same front panel 21 used for image exposure and the back panel 23 is mounted. This completes Photo 1A.

After mounting the back panel 23, the protrusion 2
The tips of the holes 14a-d and the peripheral portions of the holes 231a-d may be welded to each other, or they may be fixed to each other by using an appropriate adhesive.

According to the manufacturing method of the photograph 1A described above, since a commercially available photographic film can be used as the photographic material 22, a large amount of the photograph 1A can be manufactured at low cost. Further, since the developing device which has been conventionally used for developing and fixing the photographic material 22 can be used as it is, there is no need for facility investment for that and the manufacturing can be performed at low cost. Since the photographic emulsion layer 222 of the photographic material 22 can be brought into close contact with the lower surface of the lenticular lens 211, the image projected on the photographic emulsion layer 222 is not blurred and a sharp image can be obtained. Even if the image exposure, development, or fixing to the photographic material 22 fails, it can be redone using another photographic material 22,
Since the entire photograph 1A is not shabby, the yield is improved. Since the same front panel 21 that is used for image exposure of the photographic material 22 is used,
Since the front panel 21 does not require high dimensional accuracy, the front panel 2
1 can be manufactured at low cost.

In the above photograph 1A, the shape of the protrusions 214a to 214d provided on the front panel 21 is cylindrical.
Other various shapes such as an elliptic cylinder, a triangular prism, a quadrangular prism, and other polygonal prisms may be used. Further, it may have a long shape along the surface of the front panel 21.

In the above photograph 1A, the photographic material 22
Although the same front panel 21 as the image-exposed front panel 21 is used, if the dimensional accuracy of the front panel 21 is high, they can be separated. In that case, the photographic material 22 on which an image is formed by imagewise exposure may be printed on a sheet as an original plate, and the printed material may be used as the photographic material. A positioning mark for opening the holes 223a and 223b may be printed.

FIG. 4 is a view showing a photograph 1B of another embodiment. FIG. 4A is a front view and FIG. 4B is a sectional side view. Photo 1B comprises a front panel 21B, a photographic material 22B, and a back panel 23B.

The front panel 21B is made of transparent synthetic resin and has a rectangular lenticular lens 211B in the center of the surface.
And a recess 218 is formed in the center of the back surface. Two engaging portions 219 are provided near the corner of the inner edge of the recess 218.
a and b are formed.

The photographic material 22B has an outer dimension slightly smaller than the inner circumference of the recess 218 in consideration of expansion and contraction due to temperature change. The photographic material 22B includes an engaging portion 219a,
Engagement recesses 229a and 229b are provided at positions corresponding to b.

The back panel 23B is made of a transparent synthetic resin, and has an outer dimension that fits into the recess 218 of the front panel 21B. According to the above-mentioned photograph 1B, since the photographic material 22B and the back panel 23B are fitted in the recess 218 of the front panel 21B, the front panel 21B and the photographic material 22B and the back panel 23B are reliably positioned. In Photo 1B, a lenticular lens is provided on the surface of the back panel 23B to form a front panel.
It may be used as a back panel without providing a lenticular lens on the.

In the above photographs 1A and 1B, the back panels 23 and 23B may be used for image exposure. Other,
The structures, shapes, dimensions, materials, and manufacturing methods of the photographs 1, 1A, and 1B can be appropriately changed in accordance with the gist of the present invention.
