Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a background and a fine optical holder for synthesizing a screen used for synthesizing a background and a screen on a subject such as a person or an object.

[0002]

[Prior Art]

 Conventionally, a screen process is generally used to add a background to a subject. In addition, the background was formed on the subject by projecting a positive film for the background with a slide projector to photograph the subject.

However, in the above technique, due to the limitation of the screen process, the outline of the subject is black and the desired one cannot be obtained, and the entire photograph including the legs of the person, object, etc. is photographed together with the background. There was a drawback that I could not fit in.

[0004]

[Problems to be solved by the device]

 In the present invention, by interposing a positive film between the light-shielding plate and the film for photography, it is possible to capture the entire subject, which was not possible with the conventional screen process. By adjusting the sense of perspective to the screen, etc., the purpose is to eliminate the discomfort that tends to occur in composite photographs and to obtain natural composite photographs that do not have discomfort. In addition, the conventional technology eliminates the drawbacks that the entire part including the legs of a person or an object could not be stored together with the background, and created a composite photograph that completely contained the legs of a person or an object together with the background. The purpose is to do.

【Example】

 In the figure, reference numeral 1 denotes a frame-shaped casing, and an upper frame 2 of the casing 1 is provided with light-shielding plates 3 and insertion holes 5 and 6 for a positive film holder 4. The insertion holes 5 and 6 are completely shielded from light at the entrance. The light shielding plate 3 and the positive film holder 4 are provided with the slide grooves 9 and 10 on the inner surfaces of the both side frames 7 and 8 of the housing 1 so that the light shielding plate 3 and the positive film holder 4 can be slid smoothly. The positive film holder 4 is provided with positive film hold rails 12 and 13 on both sides. The lower frame 11 of the housing 1 is constructed so that it can be opened and closed, and the photographing film is taken in and out. The suction plate 14 is fixed to the housing 1 by being positioned at the rear of the positive film holder 4, and holding rails 15 and 16 for photographing film are provided on both sides of the suction plate 14, and the flat surface of the suction plate 14 is provided. Several air suction holes 17 are drilled in the. An air suction pipe 18 is attached above the housing 1, and air is sucked between the suction plate 14 and the rear frame 19 of the housing 1 by the air suction pipe 18, so that the photographing film 20 is sucked. It is configured to adsorb to 14.

In order to synthesize a background and a screen according to the present invention, first, a positive film in which a landscape or the like is photographed is prepared and prepared, but it is also possible to select from commercially available ones. On the other hand, the film 20 for photography is attached to the hold rails 15 and 16 of the suction plate 14 in the housing 1, and air is sucked from the air suction pipe 18 to suck the film 20 for photography on the suction plate 14 to shield light. After pulling up the plate 3, the shirt is pushed and the subject object such as a person or an object is photographed to make the first exposure. Next, as the second exposure, both side edges of the positive film are inserted into the hold rails 12 and 13 to be fixed to the positive film holder 4, and are inserted through the insertion holes 5 and 6 of the upper frame 2 of the casing 1 to slide grooves. Pass it to 9, 10 and slide it until it hits the lower frame 11. After that, press the second shirt to finish shooting. When the positive film holder 4 is inserted, it is possible to freely select which of the slide grooves 9 and 10 is to be inserted, and the perspective is adjusted by changing the focus of the background screen. You can In this case, the slide groove 9 is more distant from the photographing film 20 and the focus is out of focus, which gives the appearance of a distant view. In addition, if the camera angle is adjusted to the shooting viewpoint that is the background, a more unnatural composite photograph can be obtained.

[0007]

[Effect of the device]

 As described above, the light-shielding plate 3 and the positive film holder 4 and the through-holes 5 and 6 that are completely shielded from light are provided in the upper frame 2 of the frame-shaped casing 1, and the side frames 7 and 8 of the casing 1 are provided. The light shielding plate 3 and the slide grooves 9 and 10 of the positive film holder 4 are provided on the inner surface, respectively, so that the lower frame 11 of the housing 1 can be opened and closed, and it is positioned behind the positive film holder 4 and sucked into the housing 1. The plate 14 is fixed, several air suction holes 17 are formed in the plane of the suction plate 14, and an air suction pipe 18 is attached above the housing 1 to attach the positive film between the light shielding plate 3 and the photographic film 20. By eliminating the discomfort that is typical of composite photographs in the screen process of the conventional technology, the viewpoint of the camera can be freely changed, and the perspective of the background and screen can be adjusted to eliminate humans, objects, etc. of It is possible to photograph the surface synthesized as a more natural one photograph. Further, there is an effect that the entire body including the legs of a person or an object can be completely accommodated together with the background and the screen.
