Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a baseball simulator provided with a stereoscopic movie film F and a stereoscopic movie projector M for projecting the stereoscopic film F so that it can be observed through an observation lenticular screen S.

The three-dimensional movie projector M comprises a projection light source 1,
Shutter 2 for projection, lenticular screen S for observation, film winding device 3, and hood 4 for observation
And the viewer 5 is a stereoscopic film F
Can be observed with transmitted light through the observing lenticular screen S.

The projection shutter 2 is configured to repeat opening and closing of the shutter 32 times per second in accordance with the winding speed of the stereoscopic film F.

The lenticular screen S for observation is
Lenticular width W of lenticule lens is 100
Consists of micron lenticular sheets, 2 vertical
It has a size of 0.32 centimeters and 25.40 centimeters (8 inches x 10 inches).
As will be described in detail later, the transmitted light of the stereoscopic movie film F is dispersed so that different images are observed by the right eye and the left eye of the observer 5.

In the present embodiment, the observation hood 4 is configured so that the observer 5 can observe the observation lenticular screen S from a position where the visual distance L is 35 cm to 40 cm. Therefore, the observer 5 naturally and clearly observes the entire screen of the lenticular screen S for observation, but does not recognize the streaks of the lenticular lens of the lenticular screen S for observation, and the image quality is high. You can observe the 3D screen of.

That is, in general, when a human observes a screen such as a photograph, it is said that the range of the effective visual field in which the screen can be observed with the eyeball fixed without moving the eyeball is about 30 °. Therefore, the height is 20.32 cm and the width is 2.
In order to naturally and clearly observe the entire screen having a size of 5.40 cm, it is preferable to observe from a position having a viewing distance of about 35 cm to about 40 cm. On the other hand, the decomposition ability of the human eye is generally said to be about 1 minute, as described above. Therefore, the viewing distance is about 3
When observing from a position of 5 cm to about 40 cm, if a lenticular screen with a lenticule width of 145 microns or less is used, the lenticule width will be less than the resolution of the human eye, and Is unable to recognize streaks on the lenticule lens.

The three-dimensional movie film F is formed of a plurality of movie films for each camera obtained by intermittently photographing the cameras at a constant time by synchronizing the cameras with each other. It is created by synthesizing using a lenticular screen.

FIG. 2 shows a method for producing five motion picture films N1 to N5 as a plurality of motion picture films simultaneously photographed by five motion picture cameras C1 to C5 as a plurality of motion picture cameras. It is shown. The five movie shooting cameras C1 to C5 are located at the rear side of the batter box 6 or the home base 7 at a height corresponding to the eye level of the batter, the catcher, or the umpire. 7 are arranged at intervals h along the lateral direction.

The five motion picture films N1 to N5 show how the pitcher 8 pitches the five motion picture cameras C1 to C1.
By C5, each camera is synchronized and photographed at the same time.

In the present embodiment, a movie shooting camera C1
The spacing h at which ~ C5 is located is selected to be 32.5 millimeters.

When shooting from the batter's box 6, the five movie shooting cameras C1 to C5 are arranged at equal intervals h and follow the ball 9 as if they were the line of sight of the actual batter. The camera is operated so that it can be rotated.

During shooting, the camera lenses of the movie shooting cameras C1 to C5 are always adjusted to the sphere 9 by the automatic focusing device, such as the line of sight of an actual batter. When the camera lens is selected and the diaphragm device is adjusted, the observer can clear the images of the pitcher 8 and the sphere 9 as much as possible in the completed stereoscopic film F while the camera lens is always focused on the sphere 9. It is selected and adjusted so that it can be recognized by the camera.

In the present embodiment, the focal length f of the camera lens is 50 mm, that is, a standard lens is adopted as the visual sense of an actual batter.

By the way, according to the official rule of baseball, the distance from the pitching plate 8a to the home base 7 is about 18 meters.

FIG. 3 shows five movie films N1 to N5.
Lenticular screen Sg for each frame
A method for producing a stereoscopic movie film F which is composed of a plurality of continuous stereoscopic photographs p which are respectively synthesized by using the above is shown. In the figure, a stereoscopic photograph p, which is one frame of the stereoscopic movie film F, is a negative frame n1, n2, which is one frame of each of the five movie films N1 to N5 taken at the same time.
It is created by synthesizing n3, n4, and n5, and is composed of the same thing as a spectroscopic stereoscopic photograph with a lenticular lens.

The stereoscopic movie film F before exposure is set in close contact with the focal plane side of the synthesizing lenticular screen Sg. The lenticular screen Sg for composition is composed of a lenticular sheet having a width of one lenticule W of 100 microns, like the lenticular screen S for observation provided in the projector M for stereoscopic movie mentioned above.

The negatives n1 to n5 are magnified and projected on the synthesizing lenticular screen Sg by the magnifying lens 10 and printed on the stereoscopic film F. In this embodiment, the size of the stereoscopic photograph p, which is one frame of the stereoscopic movie film F, is 20.32 cm in height and 2 in width.
5.40 cm.

The relative positional relationship of the negatives n1 to n5 with respect to the magnifying lens 10 and the synthetic lenticular screen Sg are different so that the angles of the optical axes sequentially change between the negatives n1 to n5. N1 to N5 are configured to be sequentially projected and printed from different angles.

FIG. 4 shows a synthetic lenticular screen Sg on which the negative images of the negatives n1 to n5 are projected. The negative image is composed of a pitcher 8 and a sphere 9.

In FIG. 4, the image of the negative n3 is shown by the solid line, the images of the negatives n2 and n4 are shown by the one-dot chain line, and the images of the negatives n1 and n5 are shown by the two-dot chain line. The projection of the plurality of negatives n1 to n5 is performed so that the images of the sphere 9 are coincident with each other on the combining lenticular screen Sg.

FIG. 5 shows a state in which the negative image of the negative n3 projected on the synthesizing lenticular screen Sg is condensed by the lenticule lens and recorded on the stereoscopic film F. ing. The negative image of the negative n3 projected on the synthesizing lenticular screen Sg is divided by the aperture width of each lenticule lens, that is, one lenticule width W, and condensed.
A plurality of line images j3 are recorded on the stereoscopic movie film F.

FIG. 6 shows the line images j1 to j of the negatives n1 to n5.
5 is recorded on the stereoscopic film F. Since the negatives n1 to n5 are projected from different angles, the line images j1 to j5 are recorded in a dispersed state in the range of one lenticule width W.

Since the line images j1 to j5 have a finite width, the one lenticule width W is at least a line image j1 in consideration of the dividing ability of the photographic emulsion layer of the stereoscopic film F. It is necessary to have a width capable of effectively imprinting ~ j5. It is also experimental or experiential that it is effective to project many negatives in order to obtain a good stereoscopic effect while preventing blurring and flicker of the image, due to the parallax between the subject images. The lenticular screen Sg for synthesis and the one lenticule width W of the lenticular screen S for observation described above have been demonstrated.
In consideration of the above, is selected so that the stereoscopic image formed by the completed stereoscopic film F has high image quality.

When the stereoscopic movie film F produced in this manner is again spectrally observed by the stereoscopic movie projector M equipped with the observation lenticular screen S as described above, the left and right sides of the observer 5 are observed. Since different images are observed in the eyes of the observer,
It is possible to stereoscopically observe the pitching form of the pitcher 8 and the state of the ball 9 pitched by the pitching form, which are recorded in (3).

FIGS. 7A, 7B, and 7C show examples of screens projected on the observing lenticular screen S of the stereoscopic movie projector M. The image shown in FIG. 7 shows the pitcher 8 from the position on the rear side of the home base 7.
This is a part of the stereoscopic film F for continuously shooting the appearance of the pitching ball 9 from the start of the pitching form until it reaches the home base 7, and this screen is observed. By, for example, from the perspective of the catcher or referee (referee), for example, strike or ball, straight, curve, shoot or other type of ball, in-course or out-course, or higher or lower, etc. It is configured so that the type of sphere can be observed.

In this embodiment, the stereoscopic film F
Is created for each sphere type, and when set on the winding device 3 of the projector M for stereoscopic movie, it is configured so that which sphere type of image is projected can be selected.

A determination unit 101 is configured to determine whether or not the type of sphere recorded on the projected three-dimensional movie film F matches.

The judging means 101 is a three-dimensional movie film F.
When set to the stereoscopic movie projector M, the disc type discriminating information (not shown) recorded in a part of the stereoscopic movie film F outside the stereoscopic photograph p is read, and the stereoscopic movie film F is projected. After that, the observer 5 selects the sphere type discriminating switches 13a, 13b, 14a, 14b, 14c,
14d, 14e, 14f, 19i, 19o, 20h, 2
As 0l is operated, the discrimination information of the type of the ball and the observer 5
It is determined whether or not the result of the determination of the type of sphere matches, and if they match, a bell sound is emitted from the speaker 15, and if they do not match, a buzzer sound is emitted from the speaker 16 to the observer 5. On the other hand, it is configured to notify the correct or incorrect answer of the ball type discriminating power.

As described above, the baseball simulator according to the present embodiment is small in size and can be placed on a table or the like, and by seeing a stereoscopic image in the classroom, it is possible to practice at a baseball field even on a rainy day. Similarly, it is possible to train sports skills such as discriminating ability and eyeball selection, and it is also convenient to arrange many devices and simultaneously train many trainees at the same time. Further, the training can be performed more effectively by changing the order of the observed ball types. Further, a set of a plurality of stereoscopic movie films F is continuously projected, and the result of the sphere type discrimination that the observer 5 discriminates each time one stereoscopic movie film F is projected is stored in the switch box B. Even if it is configured to be stored in the memory and to notify the observer 5 of the correct answer or the incorrect answer after the completion of the projection of the set of stereoscopic film F, the training is performed more effectively. be able to.

[First Alternative Embodiment] The subjects photographed by the plurality of movie photographing cameras C1 to C5 are not limited to the pitcher 8 and the ball 9 thrown by the pitcher 8, and may be added as appropriate. For example, as shown in FIG. 9, almost along the ball muscle of the ball 9 thrown by the pitcher 8,
A plurality of third party subjects for observation 18 may be arranged.

In this another embodiment, the third party object for observation 18 is composed of a standing sign coated with a checker pattern, and as shown in FIG. 10, from the pitching plate 8a to the home base 7, A plurality of spheres 9 are arranged on both sides of the sphere 9 at equal intervals with an interval H. 11 (A), (A), and (C) show an example of a screen projected on the projector M for stereoscopic movie according to this another embodiment. In the image shown in FIG. 11, the observer 5 feels a good stereoscopic effect by the image of the sphere 9 and the image of the observation third-party subject 18 which appears relatively in focus as the sphere 9 advances, The pitching form of the pitcher 8 and the kind of the ball 9 can be observed.

As shown in FIG. 10, in this embodiment, the interval H at which the third party subject for observation 18 is installed is 2
The meter is adopted. In addition, movie shooting camera C
1 to C5 are installed at a position about 3 meters behind the home base 7. The other values are the same as those in the above-mentioned embodiment.

In the present embodiment, the parallax value X between any one of the third party objects for observation 18 and the style of the pitcher 8 or the ball 9 thrown by the pitcher 8.
Takes the values shown below. The parallax value X is calculated by the following formula. X = R · Z · f · (1 / K-1 / B) = {Z · (BK) · f · R} / (B · K) However, R is negative n1 to n5 and stereoscopic photo p. Magnification ratio between and about 8 times. f is the focal length of the camera lens,
50 mm. K is the distance to the sphere 9 or the distance to the pitcher 8 or an observation third-party subject 18 positioned in front of the sphere 9, and B is the observation third-party subject 18 positioned behind the sphere 9. Or a distance to the pitcher 8 or the sphere 9 and a value that differs depending on each stereoscopic photograph p.

Z is an intersection point from a point when a perpendicular line is dropped from the sphere 9 to a line parallel to the horizontal direction of the home base 7 on which the camera lenses of the movie shooting cameras C1 to C5 are arranged. Is the distance from the center point of the camera lens of the movie shooting camera located farthest from. However, it is assumed that the intersection is not located outside the center points of the camera lenses of the movie shooting cameras C1 and C5 located at both ends. In FIG. 10, since the sphere 9 is located in front of the movie shooting camera C3, Z is from the center point of the camera lens of the movie shooting camera C3 to the camera of the movie shooting camera C1 or C5.

h is the distance between the movie shooting cameras C1 to C5 and is 32.5.
Mm. ). Actually, the ball 9 is a type of ball (for example, in-course, out-course, curve, shoot, etc.)
The maximum allowable value of Z is that the sphere 9 is located in front of the movie shooting camera C1 or C5, and therefore the farthest movie shooting camera C5 or It means the distance to the center point of the camera / lens of C1, and Z = (N−1) · h (where N is
Five movie shooting cameras C1 to C5. ). In this another embodiment, the case where the sphere 9 is located outside the center point of the camera lenses of the movie shooting cameras C1 and C5 located at both ends is excluded. This is because the three-dimensional motion picture film F to be created is for reproducing a scene viewed from the viewpoint of a batter, a catcher, or a referee.

First, in the three-dimensional photograph p in the state where the pitcher 8 is pitching as shown in FIG. 11A, the subject is the pitcher 8, and the pitcher 8 is placed in front of it. Since the stereoscopic view is made by comparison with the observing third party subject 18,
The distance K is 18 meters, and the distance K is 16 meters when the distance to the observation third party subject 18 immediately before the distance K is 18 meters. In this case, the parallax value X is 0.361 millimeters.

When the distance K is the distance to the second observation third-party subject 18, it is 14 meters, and in this case, the parallax value X is 0.825 millimeters.

In the three-dimensional photograph p in the state where the sphere 9 is approaching the home base 7 as shown in FIG. 11A, the subject to be the subject is the sphere 9 and the sphere 9
Is a third-party subject for observation 1 placed in front of it.
8 or the observation third-party subject 18 arranged behind it is stereoscopically viewed, so the distance between the sphere 9 and the observation third-party subject 18 closest to the sphere 9 is If the distance H between the third party subject for observation 18 is 2 meters,
The maximum distance is 1 meter. Therefore, for example, the sphere 9
, The distance K is 9 meters, and the distance B is one to the third party object for observation 18 behind the distance K. Is 10 meters, and in this case, the parallax value X is 0.578 millimeters.

If the distance B is the distance to the second observation third-party subject 18, the distance is 12 meters. In this case, the parallax value X is 1.444 millimeters.

Further, in the stereoscopic photograph p in the state where the sphere 9 is close to the home base 7 as shown in FIG. 11C, similarly, the distance K is set to the foremost third observation point. Assuming that the distance to the subject 18 is 3 meters and the distance B is 4 meters as the sphere 9, in this case,
The parallax value X is 4.333 mm.

Therefore, in the baseball simulator of this another embodiment, the lenticular screen S for observation has a length of 20.
The pitcher 8 has a size of 32 cm, a width of 25.40 cm, and a lenticule width W of 145 μm to 80 μm.
When shooting the sphere 9 and surrounding objects thrown from the position on the home base 7 by a plurality of movie shooting cameras C1 to C5, a plurality of observations are made at intervals H substantially along the ball line of the sphere 9. A third-party subject 18 is arranged, and the parallax value X between any one of the plurality of third-party subjects for observation 18 and the style of the pitcher 8 or the ball 9 thrown by the pitcher 8 is set to approximately 0. It is set to 3 mm to 4.0 mm.

The close-up image shown in (a) is taken by zooming up the zoom ratio of the movie shooting cameras C1 to C5 at the time of shooting.

In this case, the projector M for stereoscopic movies is provided with a plurality of lenticular screens S for observation having different lenticule widths W, and the lenticule widths different as the close-up image is projected. It may be configured to switch to the W observation lenticular screen S.

[Third Alternative Embodiment] Film F for 3D movie
Although the observation lenticular screen S and the observation lenticular screen S are separately configured in the above-described embodiment, they may be integrally configured. For example, the observation lenticular screen S is not provided in the stereoscopic movie projector M, but a strip-shaped lenticular screen that constitutes the stereoscopic film F itself.
It may be composed of a sheet. In this case, the observation lenticular screen S is composed of a plurality of motion picture films N.
It is also used as a lenticular screen for synthesizing when synthesizing 1 to N5 to form a stereoscopic film F.

Further, the integral type three-dimensional movie film F is

FIG. 13 shows a conventional material,
In FIG. 14, a direct emulsion type material is shown. In the conventional material, as shown in FIG. 13, the lenticular sheet S ′ is formed on the upper surface side of the film base 11 via a double-sided adhesive film 12 having adhesive layers formed on both sides thereof, as shown in FIG.
And a layer of various chemicals constituting the photographic emulsion layer E is formed on the lower surface side of the film base 11.
The double-sided adhesive film 12 has a thickness of 80 μm, and the film base 11 has a thickness of 180 μm.

The light projected on the lenticular sheet S'is deflected and diffused to some extent when passing through the double-sided adhesive film 12 and the film base 11, so that the image recorded in the photographic emulsion layer E is blurred. Distortion will occur and the quality of the recorded image will deteriorate.

In the direct emulsion type material, as shown in FIG. 14, the photographic emulsion layer E is directly formed on the lower surface side of the lenticular sheet S ', and the double-sided adhesive film 12 and the film base 11 are provided. Has not been done. Therefore, since the double-sided adhesive film 12 and the film base 11 do not cause deflection and diffusion, the image quality of a recorded image is significantly improved.

[Other Embodiments] The size of the lenticular screen S for observation, the lenticule width W, the viewing distance L in the projector M for a stereoscopic movie, etc. are taken into consideration in view of the image quality of the stereoscopic image by the stereoscopic film F. Therefore, it can be changed appropriately.
