Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and a tool for viewing a stereoscopic photograph or its printed matter as a stereoscopic image.

[Conventional technology]

2. Description of the Related Art Conventionally, stereoscopic photographs taken with a dedicated camera for stereoscopic photography or a camera with stereoscopic photography accessories attached to a normal photography camera have been viewed as stereoscopic images.

The principle of two-body photography is that, in the case of a dedicated camera, two photographic lenses are installed at a distance from each other on the camera body, and the subject images that pass through each lens are formed at different positions on the film. A set of stereoscopic photographs is obtained, and the subject distance range and degree of stereoscopic effect in this case are determined by the distance between the two photographing lenses and the focal length of the lenses. In addition, in the case of a camera equipped with a three-dimensional photographic accessory that combines a mirror in front of one photographic lens, the image of the optical axis Pa is reflected by the mirror M, as shown in Fig. 5.
a, is reflected by M a 2, passes through the camera lens L, and forms an image on the film F as an object image a, and the image of the optical axis pb is reflected by mirrors Mb, Mb, passes through the lens L, and forms an image on the film F. By focusing the object image on film F, a set of three-dimensional photographs in which object image a and object image A are adjacent to each other is obtained in one frame of film F. In this case, the subject distance range and degree of stereoscopic effect are determined by the focal length of the camera lens, the mounting angle of each mirror, and the mirror Ma.
It is determined by the M interval between and Mb.

In order to view a photographed stereoscopic photograph as a stereoscopic image, various types of box-shaped, one-piece viewing equipment called a so-called stereo vinyl are used. As shown in FIG. 6, the basic structure of these ornamental tools is that one end 21 is provided with two eyepieces 22a and 22b to serve as a viewing section, and the other end 23 is provided with an eyepiece 22a.

An image section is provided by providing a section into which stereoscopic photographs 25a and 25b are pasted or fitted via a middle section 24 having a length that is approximately the same as the focal length of the section 22b.

[Problem to be solved by the invention]

When viewing a stereoscopic image using a conventional viewing tool as shown in FIG. 6, only one set of stereoscopic photographs can be pasted or inserted into the image area and viewed through the viewing area. therefore,
Naturally, the three-dimensional images that can be viewed using such viewing tools are the same as those taken at a certain time by a certain camera.
There is only one set of 3D photos, and the other sets of 3D photos taken separately can be viewed separately.

However, as mentioned above, 3D photographs taken with a dedicated camera for 3D photography or a camera equipped with an accessory for 3D photography may vary depending on the specifications of the camera or the accessory used to take the image, and the distance range and range of subject distance within which a 3D effect can be obtained may vary. The degree of three-dimensionality is determined. Therefore, even if the obtained stereoscopic photograph is viewed as is using conventional viewing tools, there is a dissatisfaction that, for example, although the close-up view has a three-dimensional effect, the distant view lacks a three-dimensional effect and lacks impact. Further, for example, in commercial photography, a composite photograph of separately taken photographs is often used, but such a composite photograph cannot be viewed as a three-dimensional image.

In addition, there are various types of conventional 3D image viewing tools, including molded synthetic resin products and simple models that can be assembled by folding sheet-like objects, but all of these tools are simply for viewing 3D photos. However, its scope of use is limited, and it cannot be applied to other uses or entertainment.

The problem to be solved by the present invention is to increase the stereoscopic effect obtained from stereoscopic photographs and to expand the scope of use of stereoscopic photographs and viewing tools.

[1! ! ! Means for Solving the Problem] The stereoscopic image viewing method of the present invention involves attaching another stereoscopic photograph or its printed matter over a stereoscopic photograph or its printed matter via a raised part to form an image area, and This is a method of peeking into the image area using a viewing tool.

As the viewing tool, a pair of eyepiece lenses may be provided at one end of a sheet parallel to the edge of the sheet with a distance between the eyes to form a viewing section. Further, the other end opposite to the peep section is used as an image section, and the image is formed in the same image section, and the peep section and the image section are arranged to face each other across the focal length of the front eyepiece. It is possible to create an ornamental tool that is foldable and has a viewing part and an image part integrated.

[Effect]

In the present invention, one set of stereoscopic photographs is pasted or printed, and another set or sets of stereoscopic photographs or their prints are folded and superposed on top of the three-dimensional photographs to form an image. This foldable, superimposed set of stereoscopic photographs or prints thereof can be either partially cropped images or partially printed images on a transparent film. In this other set of stereoscopic photographs or printed matter, when the sheet-like image area is placed in the viewing position, the folded portions stand up, and each set of stereoscopic photographs or printed matter is spaced apart so that each surface is parallel to the other. line up. When the image portion consisting of the plurality of sets of stereoscopic photographs or printed matter is viewed through a viewing tool, each stereoscopic photograph or printed matter is seen as a three-dimensional image.

In addition, ornamental tools that integrate the viewing part and the image part with one end of one sheet as the viewing part and the other end as the image part can be used by writing or printing on the margin of the sheet. It can be used as documents, cards, advertising media, etc.
