SU148718A1 - Universal machine for the production of stunt and combined motion pictures - Google Patents

Description

Universal machines for producing stunt and combined motion-picture frames are known, which consist of a movie camera, frame-by-frame projectors, an optical system, and electric motors connected by a common electrical circuit (see, for example, ed. St. No. 127575 for cells 57a, 53).

The disadvantage of these machines is the impossibility of combining the filing of a frame, a layout, a drawing, etc. in the exposure window in a single image. In addition, these machines are complex in their constructive implementation. The proposed machine is devoid of the indicated disadvantages. The essence of the invention is that a beam splitter cube is used in the machine, which is located in front of the camera. Supply cube; It is a translucent layer in the place of gluing two rectangular prisms.

The drawing schematically shows the proposed machine.

The machine consists of a cast iron base, a beam-splitting cube 2, projection units 3 to 4, a vision device 5, a screen 6, a projector 7, patterns 8, heat filters 9, a mirror W, external aluminized capacitors //, a frame 12 for precise sharp porridge, a curtain 75, mirrors 14 for exterior, aluminization, lenses / 5, 16, 17 and 18, lamps / 9 and 20, and a viewing console 21.

The beam splitting cube 2 is glued together from two straight prisms and is provided with a translucent layer in the place of pasting. The cube is located in front of the shooting camera 22 and forms a display, given by the projection nodes 3 n 4, directed it to the personnel window of the shooting camera and at the same time into the lens / 5 of the visio-nitro device, which projects the combined image on the screen 6.

The proposed machine eliminates the possibility of double contours, provides 9-fold zooming, allows you to get a combined image from 2 projectors (with absolutely sharp porridge of any figuration), allows you to combine shooting a picture or layout while imprinting a previously removed actor's scene. When working with black-and-white films, there is the possibility of a very wide adjustment of the light on the projectors, which eliminates the need to produce very accurate lavenders in the film lab and allows them to be precisely adjusted in terms of tonality but the control device. In addition, the power of the network flow of projectors allows working on low-sensitive materials.

The machine provides the possibility of simultaneously combining in one two-scale images, while simultaneously hitting or leaving one of these images:

The presence of an accurate screen for visual control facilitates the layout of the combined frame, the tonal adjustment of its components. It almost eliminates the need to make laboratory samples for exposure and provides an opportunity to continuously monitor the shooting process and to eliminate in a timely manner the defective shots available on lavender.

A universal mask for producing stunt and combined motion-picture frames consisting of a filming camera, frame-by-frame projectors, an optical system and associated electric motors with a common electrical circuit, characterized in that, in order to combine frame preparation, layout, design, etc., in the exposure window in one whole image, in it a beam-splitting cube is used, equipped with a translucent layer in the place of gluing together two rectangular prisms, mounted in front of the shooting camera.
