2. Description of the Related Art Recently, stereoscopic viewing has been actively used in the field of education such as terrain and astronomy, but left-eye and right-eye pictures placed at specific positions are separated from each other by a specific distance. Stereoscopic viewing was performed by viewing with a stereoscope. However, with this method, it was possible to see only one person at a time, and it was not always possible to effectively raise the educational effect.

On the other hand, in the field of moving images in particular, a large number of people can see the images for the left and right eyes by sharing the screen and displaying them on a large TV screen at the same time, and viewing them with a polarizing filter or a time-division stereoscopic mirror. There is a method that can be viewed stereoscopically at the same time. However, these methods require a device for projection which is special and expensive and requires precise adjustment, and is expensive for displaying on a large TV screen. Since it requires a digital converter and the like, it has very poor versatility.

[0008]

The binocular stereoscopic slide according to the present invention first converts a left-eye picture and a right-eye picture for binocular stereoscopic vision into digital signal data, respectively. Using the computer, one of the left-eye picture and the right-eye picture converted into this digital signal is displayed on the corresponding side of the pair of left and right display frames of the CRT screen, trimmed to the desired composition, and then digitally displayed on the other side. The picture for the other eye converted into a signal is displayed and trimmed so that both pictures can be viewed stereoscopically. The left-eye and right-eye pictures thus positioned are printed on a slide film to create a slide.

As a result, a large number of people can simultaneously stereoscopically view a left-eye picture and a right-eye picture on a screen or the like with a projector and view them with a peep glasses type stereo viewer. Further, the projector and the peep glasses type stereo viewer are simple and inexpensive devices and enable stereoscopic viewing in a wide range of places. Also,
By converting the left-eye and right-eye pictures into digital signal data and printing them on a slide film, the reproducibility and fidelity of the slide to the original are high, and the left-eye picture and the right-eye picture for selecting the desired composition and stereoscopic viewing It is possible to arbitrarily decide the relative positional relationship of the picture.

The conversion of the left-eye picture and the right-eye picture into digital signal data may also be performed using a film scanner or other suitable reading device, or an electronic photographing device such as a digital still camera or a digital video camera. it can. In addition, when trimming the left-eye picture and the right-eye picture so that they can be viewed stereoscopically, it is also possible to check them on the CRT screen using the peep glasses type stereo viewer, which allows slides that cannot be viewed stereoscopically. Prevent it from being created. Further, when the left-eye and right-eye pictures are printed on the slide film, they can be performed using a digital film recorder or another film printing apparatus.

In addition, recording the converted digital signal data of the left-eye picture and the right-eye picture and / or the set digital signal data of the left-eye picture and the right-eye picture on a photo CD, an optical disk or another recording medium. It also ensures the reproducibility and fidelity of original preservation and iterative production.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a binocular stereoscopic slide according to an embodiment of the present invention basically has a left-eye picture 1 and a right-eye picture taken for binocular stereoscopic vision. Created using picture 2. The left-eye picture 1 and the right-eye picture 2 are usually optically photographed by a well-known stereoscopic photographing technique. The left-eye picture 1 and the right-eye picture 2 that are optically captured are read by a reading device such as a film scanner and converted into digital signal data.

It should be noted here that the left-eye picture and the right-eye picture can also be pictures taken by an electronic photographing apparatus such as a digital still camera or a digital video camera which records an image by digital signal data. At this time, it will be easily understood that the operation of converting the optically photographed film into digital signal data is unnecessary.

It is preferable that each of the converted digital signal data of the left-eye picture and the right-eye picture is once recorded on a photo CD, an optical disk, a hard disk, or any other suitable recording medium. As a result, the left-eye picture and right-eye picture as the original can be saved as digital signal data respectively, which not only prevents deterioration over time, but also creates slides with different compositions when necessary. It can be used at any time.

Then, using a computer, as shown in FIG. 2, one of the digitized left-eye picture 1a and right-eye picture 2a (left-eye picture 1a in the figure) is paired on the left and right of the CRT screen 3. The images are displayed on the corresponding sides of the display frames 4 and 5 (the left display frame 4 in the case shown), and moved or enlarged or reduced to achieve a desired composition for trimming. This trimming is performed so as to fit the purpose of use of the slide, and is not particularly limited, but it is intended so that more effective stereoscopic vision can be performed when stereoscopically viewed. It is desirable to select the part so that it becomes the center position.

When the trimming of the left-eye picture 1a is completed, the right-eye picture 2a is displayed in the right display frame 5 of the CRT screen 3 as shown in FIG. 3, and the left-eye picture 1a displayed on the CRT screen is displayed. The right eye picture 2a is trimmed by moving, enlarging or reducing the right eye picture 2a while observing it with a well-known peep glasses type stereo viewer so that the right eye picture 2a and the right eye picture 2a have a stereoscopic positional relationship. As a result, it is possible to reliably prevent a slide that cannot be viewed stereoscopically from being created.

After the trimming is completed, it is preferable that the digital signal data of the left-eye and right-eye pictures 1a and 2a in the stereoscopic position be temporarily recorded on a photo CD, an optical disk, a hard disk or another suitable recording medium. This makes it possible to create a large number of slides with extremely high reproducibility and fidelity with respect to the original in the subsequent slides, and to reliably prevent the deterioration over time required for the original plate. .

The digitized left-eye and right-eye pictures 1a and 2a at the stereoscopic position are printed on a slide film by using a digital film recorder or other appropriate film printing device, and are made into a slide pack by a well-known slide making technique. Mounted and completed as a slide 6 having simultaneously left-eye and right-eye pictures 1b and 2b, as shown in FIG.

The completed slide is projected on the screen by the projector. The left-eye picture and the right-eye picture projected on the screen are stereoscopic by viewing them using the same peep glasses stereo viewer that was used when trimming the left-eye picture and the right-eye picture to the stereoscopic position. Can be seen. As described above, the equipment for stereoscopic vision is simple, and its operation does not require precision or special technology, so it can be easily performed even in places without stereoscopic projection equipment such as classrooms and conference presentations. It becomes possible to provide explanations and explanations using stereoscopic vision.
