Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to methods and apparatus for creating stereoscopic effects.

[0002]

2. Description of the Related Art A stereoscopic effect is obtained when two frames of a color-matching film showing different images obtained by simultaneously photographing an object from two positions at slightly different angles are simultaneously viewed with their eyes. . Two separate cameras may be used to capture two slightly angled separate images of an object onto two frames of color-matching film. However, it takes skill to simultaneously capture two images from an appropriate angle.

In order to simultaneously capture separate images of a slightly angled object in two frames of color-matching film,
Only one camera with two lenses has been used. However, the image of one object cannot be captured well if it is too far or too close from the camera because the distance and angle between the lenses cannot be adjusted. Such cameras are also expensive because they are used only for that purpose and are therefore not mass produced.

Whether using two conventional cameras or one camera with two lenses, a strip of color-matching film is cut and slid after development. The slides must be connected to each other. Only one pair of slides can be set in the device at a time to obtain one stereo effect. That is, a pair of slides can be set in the device only when the preceding slide pair is removed from the device. This is a waste of time. The present invention is therefore intended to solve this problem.

[0005]

The problem to be solved is to provide a rack for simultaneously carrying two cameras. This rack has a slot to allow one camera to move with respect to the rest of the cameras, and the angle between the two cameras to make the photographer more suitable for capturing better footage. It has a number of indicators to assist. Another problem to be solved is to provide a device for displaying each frame pair of color-matching film pairs in which one object is photographed at the same time so that the object can be viewed three-dimensionally. Another problem to be solved is to provide a method for creating a steric effect.

[0007]

The present invention will be described in detail with reference to the drawings. Referring first to FIGS. 1 and 2, the rack 2 is at 90 ° with the member 6.
The first camera mounting member 4 is integrated in the state of forming an angle. The member 6 is integrated with the second camera mounting member 8 at an angle of 90 °, and
It is integrated with the member 10 at an angle of 90 °. Each of the first camera mounting member 4, the member 6, the second camera mounting member 8 and the member 10 have a flat shape. Each first camera mounting member 4 and second camera mounting member 8 project from member 6 in opposite directions. The first camera mounting member 4 is extended at a position higher than the second camera mounting member 8 and the second camera mounting member 8 is extended at a position higher than the member 10.

A hole is provided in the first camera mounting member 4. In use, the first camera having a screw hole at its bottom is reversed and the knob bolt is inserted through the hole of the first camera mounting member 4 and then inserted into the screw hole of the first camera. It Thus, the first camera is mounted below the first camera mounting member 4.

The second camera mounting member 8 is provided with an elongated hole extending along the longitudinal direction thereof. A second camera having a screw hole at its bottom is maintained in an upright state, a bolt with a knob is projected through the elongated hole of the second camera mounting member 8, and then is screwed into the screw hole of the second camera. Be involved. As a result, the second camera is attached to the second camera attachment member 8.

A threaded hole is formed in the member 10. The plate 12 is integrated with a hole of a tripod (not shown). A bolt with a knob is inserted into the hole of the plate 12 and then engaged with the screw hole of the member 10. Thus, the rack 2 is mounted on a tripod along with the two cameras.

A cartridge in which a color-matching film strip is housed in a cartridge mounted on the first camera and another strip of color-matching film is mounted in a second camera as shown clearly in FIG. Is stored in.
The first camera is inverted so that the strip of colorimetric film within it is fed from the cartridge in the opposite direction to that of the second camera. However, the first camera does not necessarily have to be reversed as long as the color-matching film strip can be fed in the reverse direction while the first camera is upright. The reason for having the first camera's color-matching film strips fed in the opposite direction will be explained below.

Still referring to FIG. 3, a number of indicators are second.
It is provided on the camera mounting member 8. For example, second
The camera mounting member 8 has three indicators 14a, 14
b and 14c are provided. To image the object relatively close to the camera, the second camera is positioned relatively close to the first camera and a particular portion of the second camera is aligned with the indicia 14a. To image the object at a distance from the camera, the second camera is positioned slightly away from the first camera and a particular portion of the second camera is aligned with index 14b. To image the object relatively far from the camera, the second camera is positioned relatively far from the first camera and the particular position of the second camera is aligned with the indicia 14c. Thus, an always clear image of the object can be taken regardless of its distance from the camera.

Referring to FIG. 4, a first embodiment of the present invention is shown in which a cassette 16 is housed in a case 18.
The case has a first portion that defines a cylindrical chamber 20 and an opening that communicates with the chamber 20. Two strips of a color-matching film are accommodated in a roll in the chamber 20.

A gear 22 is mounted below the roll of the color-matching film in the chamber 20. The gear 22 is partially exposed to the outside of the case 18 through the opening. A gear 24 that engages the gear 22 is rotatably attached to the second portion within the case. A pair of wheels 26 having sprockets 28 are fixed to the gear 24 in the same center state. The sprocket 28 engages an eyelet formed in a strip of color-matching film. Wheel 2 paired with passage 30 communicating with chamber 20
6 along the perimeter and then 2 at the edge 32
It branches into one passage 30a, 30b. The edge 32 separates the two color-matching film strips into two strips, one being fed along the passage 30a and the other along the passage 30b.

Referring to FIG. 5, a cassette 34 according to a second embodiment of the present invention is shown. This cassette 34 holds two strips of color-matching film.
It is similar to the cassette 16 except that two chambers 36 are provided.

With reference to FIG. 6, after processing, each end of the strip of color-matching film is preferably
A patch is provided for closing the small hole formed therein. This patch prevents engagement of the sprocket 28 with the blocked small hole. Thus, the color-matching film will not be drawn further into chamber 20 or 36 when the strip is drawn almost completely into chamber 20 or 36, and it will be drawn from chamber 20 or 36 substantially. When fully withdrawn, it is not delivered any further along the passage 30.

Referring to FIG. 7, a projector 38 having a case 40 is illustrated. Color-matching film 2
One cassette 16 containing a strip of books is positioned within the case 40. Inside the case 40, a pair of transparent panels 42a and 42b are arranged, and a passage is defined between the transparent panels 42a and 42b. These passages are passages 30a, respectively.
And 30b. The rear portion of case 40 defines an opening through which gear 22 is partially exposed to the outside. Thus, by rotating the gear 22, it is possible to feed two strips of color-matching film from the chamber 20 along the passage 30. As the gear 22 is continuously rotated, the edge 32 portion separates the two strips of the color-matching film from each other so that each strip of the color-matching film travels along a respective path 30a, 30b. And then delivered along a passage defined between each pair of transparent panels 42a, 42b. The color-matching film strips are then fed into two chambers 44 formed inside the case 40, respectively.

Two light sources 46a and 4 are provided in the case 40.
6b is provided. These light sources include two power sources 48 mounted behind each pair of transparent panels 42a and 42b.
Power is supplied from a and 48b. The light emitted from the light sources 46a and 46b is transmitted through the transparent panels 42a and 4 respectively.
2b through each pair and then through two frames of orthochromatic film with an image of one object taken simultaneously at slightly different angles. Thus, it is possible to obtain a stereoscopic effect through the two lenses 50a and 50b attached to the front portion of the case 40. In order to further enhance the lighting effect, preferably two reflectors 52a, 52
b are provided behind the two light sources 46a and 46b, respectively.

Next, referring to FIG. 8, the cassette 34 is incorporated in the projector 38. Cassette 34
The operation of is the same as that of cassette 16 and will not be described here. Two strips of the color-matching film are drawn in opposite directions as shown in FIG. 2 so that the strips are cartridge 16 as shown in FIG.
Feeding in the opposite direction (or from the cartridge 34 as shown in FIG. 8) will result in the display of a non-opposite or non-reversed positive image on each frame pair. Although the present invention has been described above with reference to specific examples, it should be understood that many modifications can be made within the present invention.
