  • Patent number: 9849399
    Abstract: Systems and methods herein are directed to providing a visual effect background that may be added behind a transparent holographic projection screen (e.g., of a Pepper's Ghost Illusion system) that provides for greater scenic depth behind the holographic projection, regardless of the amount of actual physical space behind the transparent screen. The background, which may be used for projection-based holographic projections or video panel display projections, generally establishes an optical illusion of depth behind the holographic images (producing a depth perception or “perspective” that gives a greater appearance of depth or distance behind a holographic projection).

Objects moving in either lateral direction can be made to appear closer to or farther away from the viewer depending upon the color of the objects and surrounds. Objects that appear brighter to the left eye appear closer to the viewer when they are moving from left to right. These left eye bright objects appear farther away from the viewer when they are moving from right to left. The effect is reversed for objects that appear brighter to the right eye. Objects that appear brighter to the right eye appear closer to the viewer when they are moving from right to left. These right eye bright objects appear farther away from the viewer when they are moving from left to right. The colors of the areas surrounding moving objects can produce or contribute to the depth effect.

    Abstract: The device described here allows for the raising or lowering of the mask which sits along the bottom edge of the screen in a motion picture theater and, along with the top and two side masks, frames the entire screen. The lower mask is supported by a number of support units, each containing two arms, equal in length and pivotally joined at their apex, where they are also attached to the bar that supports the screen mask. The arms are moved further apart or closer together at their lower ends, so that they push the bar supporting the screen mask up or down. A rotating shaft, with sections of oppositely-pitched threads, is connected to a motor. Sleeves with complimentary inside threads are pivotally mounted to the support arms, such that rotation of the motor in one direction moves the loser ends of the arms further apart and rotation in the other direction brings the lower ends of the arms closer together. Thus, the screen mask can be raised or lowered by motor rotation in one direction or the other.

  • Patent number: 5013147
    Abstract: Device for reproducing stationary or three-dimensional images by projection, the photographing being effected through several objectives, each located at a different position in space; in the reproduction system, the different images, if not reproduced on a diffusion surface, do not need to be distinguished by their position on it; the projection is effected directly onto a transparent optical system, the images being distinguished from each other by their angle of projection; this optical system is formed of a sheet of vertical cylindrical lenses, the transverse size of which is not conditioned by the number of images and the aperture of which is independent of the orthoscopic viewing angle, and of a sheet of horizontal cylindrical lenses of short focal length and arbitrarily small size constituting a reproduction system which is easy to manufacture and can be adapted to any viewing angle, giving a different image at each point of viewing.

  • Patent number: 4963015
    Abstract: A method of recording an image of a scene onto cinematographic color film comprises forming a number of successive partial images through a single lens system onto each single frame of the film, the successive partial images being recorded in light of different characteristics, for example different colors. The film is projected using a conventional projector, and when viewed through appropriate filters, gives a stereo scopic effect. To get an optimum effect, the sequence in which the images are recorded should be appropriate to the predominant direction of horizontal movement in the scene. Accordingly in one form of the invention, each image is divided into a number of areas, each area in successive images being recorded in light of different characteristics, and each image having different areas recorded in light of different characteristics.

  • Patent number: 4934824
    Abstract: A method of recording an image of an object onto cinematographic color film comprises forming a number of successive images of the object through a single lens system onto each frame of the film, the successive images being recorded in light of different characteristics, for example different colors. In a preferred embodiment, each frame of the film is exposed successively to light of two or three different colors. The film is projected using a conventional projector, and when viewed through spectacles consisting of two appropriate filters gives a stereoscopic effect. The method can be used to produce a film which can also be viewed without spectacles, and is found to give enhanced sharpness and color saturation. The invention also includes a moving film camera having a mechanism for interposing a number of filters in the optical path successively during exposure of each frame so that successive images are overlaid on each frame.

  • Patent number: 4651228
    Abstract: In a method and arrangement for the representation of a halftone image upon employment of a detection-adapted grid, the halftone image formed of intensity stages is generated by picture elements of identical size situated at prescribed grid positions. A given plurality of grid positions is combined to form an image spot. The plurality of picture elements and their grid positions within an image spot defines the respective intensity stage. The grid structure is oriented on a curve of the detection limit for the perceptability of sinusoidal grids. For producing a hexagon-like impression given the employment of grid positions situated in quadratic matrices, successive change lines of joining matrices or sub-matrices are shifted relative to one another by half a side length of the matrices or sub-matrices in the formation of the image spots.

  • Patent number: 4547050
    Abstract: My invention is a three-dimensional motion picture capture and reproduction method and apparatus that allows multiple viewers to simultaneously watch the reproduction of recorded or real time 3-D pictures without the need for any special optical aids at their eyes. The playback system is compatible with all current forms of film format, television cameras and video recorders and synthesizes three-dimensional images from several lateral vantage points in the scene. The playback equipment uses a single lamp and a circular and slowly rotating platform upon which several identical projectors are affixed. The angular velocity of each projection lens node and its corresponding image surface is identical to achieve image motion compensation. Multiple images are simultaneously projected in the direction of a concaved screen through the rotation axis or another point closer to the screen. The screen is semi-specular with horizontal reflecting and vertical scatter properties.

  • Patent number: 4464029
    Abstract: Wide angle film shooting and projection of images on the inside of a spherical screen is accomplished by first shooting a scene using a "fish-eye" lens to obtain truncated circular images with their truncations along a common edge of the film. The images are projected onto the concave screen through a tele-objective, and a convex mirror in the center of the screen so that truncated portions of the film images correspond to the upper portion of the screen, which is of least significance to a viewer. Images of diameter greater than the width of the film can thus be used without loss of significant information. Images with an angular field as great as 220.degree. can be projected on the screen.

  • Patent number: 4435053
    Abstract: This apparatus forms and displays sequentially a plurality of three-dimensional images. Frames from a film strip are stroboscopically selected and projected on a moving screen. The effect may be simply a comparison of two three-dimensional images. Alternatively, an illusion of motion of a three-dimensional image may be created. Safety features prevent access to rotating parts and other features protect the stroboscope from excessive and unnecessary use. A single three-dimensional image may be selected and continuously projected on the screen.

  • Patent number: 4420230
    Abstract: A process for recording and projecting a three dimensional visual scene onto a receiving surface from which the scene may be viewed in stereopsis by the unaided human eye. A scene is recorded from right and left view positions which are laterally separated by a distance of no more than about 1 inch, and separated in a direction generally perpendicular thereto by a distance of no more than about 1 inch, groups of one or more recorded right and recorded left views are alternately projected onto a receiving surface in sequence such that the visual duration of each group varies from a minimum to a maximum time which is generally proportional to the distance of the nearest non-moving object of special regard in the scene from the recording positions and is approximately equal to the visiopsychological supression rate of the human eyes.

  • Patent number: 4349252
    Abstract: My invention relates to photographing scenes with a standard motion picture camera in which there is a relative motion between the scene and camera with the purpose of stereoscopic viewing of the motion picture without the need for viewing aids at the eye. The system is compatible with scenes photographed without this relative motion but the reproduction is flat. The film (or other appropriate media) is arrayed in a vertical plane and constrained to move horizontally around a segment of a circle of radius 2R. At the center of the film circle is a film motion compensator which can be a multi-faceted mirror drum of radius R. The film is rapidly scanned about the center of this circle by a scan projector. Projection optics on the projector, project the sequential film frames onto a relatively large circular cylindrical semi-specular screen.

  • Patent number: 4294523
    Abstract: This invention utilizes a series of two-dimensional photographs of successive cross-sections of an object. The photographs are arranged on a film strip in the order in which the successive sections appear in the object. The film strip is transparent and is intermittently illuminated as the successive frames of the film strip move across an optical path. A projection screen in the optical path is moved with respect to the optical path so that as each successive photograph is illuminated, that photograph is projected onto the screen at a successive position and so that each photograph as projected on the screen appears more remote from an observer than the preceding one. Thus there is formed on the screen a series of images which appear to an observer having persistence of vision to be a composite three-dimensional imgage. The illuminating means may omit the illumination of certain photographs of the series, so that only selected photographs are reproduced on the screen.
