  • Patent number: 9041898
    Abstract: Simultaneous movies of plural portions of a scene are acquired and shown, using one imager with electrooptical directing device to acquire, stepwise, an interleaved (e. g. alternating) sequence of subscene images. Apparatus is ideally in a vehicle: airborne or unmanned, or both. The invention records and transmits (via one data link, with no needed parallel path) the sequence as one image series; best sorts the received sequence into noninterleaved sequences, a separate sequence for each subscene; and shows these as movies. Alternatively, scene portions form a mosaic. Including gyro operation and pointing, the device best gets a new image roughly each 5 to 40 msec or less; or excluding gyros and pointing, 5 to 40 msec by FSM, 1 to 5 by MEMS, 1 to 5 (or 10) by LC, 1 by 2-axis nongimbal scanner and 0.1 to 0.2 by digigimbal. Subscene direction and focal changes best synchronize with frame reception. FSMs best have refractory bearings and electromagnetic pointing.

  • Patent number: 9041899
    Abstract: In a computerized film (digital camera action) production system, a virtual director module takes responsibility for creating sets, and enabling cinematography by creating a synthetic parallax matching of a “set” image to what would have existed before a camera in real motion about the physical location represented. This overcomes failures typical of “green screen” technology in dealing with such conditions as shallow depth of field and low light. Computer generated, synthetic sets from a 3D animator may be projected behind real actors during or after filming. Sythetic sets are seen through a virtual camera as photo-realistic because they are skinned with textures, and structured geometrically, to match reality represented by actual still photography of a physical environment, such as buildings, walls, streets, landscapes, props, and the like.

A camera is mounted onto a camera support system. The camera support system has multiple articulated joints that enable the camera support system to move the camera through a wide range. Sensors are provided at each of the articulated joints to sense any changes in orientation experienced during a scene. The sensors create corresponding data signals indicative of the movement. A scene is shot with the camera. During the scene, the camera has a shooting position that is altered using the camera support system. The sensors detect the movements and the data signals produced are saved in an electronic memory. The saved data signals are used at a later time to reproduce movements of the camera support system.

  • Patent number: 5627614
    Abstract: A method is disclosed whereby film images designed to produce a high-impact effect upon the members of an audience viewing a motion picture film are composited with other images designed to provide the conventional cinematic effect upon such audience members. "High-impact" film images photographed at forty-eight frames per second are composited with "conventional" images photographed at the traditional motion picture rate of twenty-four frames per second, with such images superimposed onto the same film frame. Certain portions of the motion picture image seen by the audience deliver a greater illusion of reality than other portions of the same motion picture image. In addition, the method described can accommodate the intercutting of discrete scenes presenting either high-impact or conventional cinema experience. The method disclosed here also allows easy conversion of films to the conventional twenty-four frames per second rate associated with conventional motion picture release and distribution.

A scene is photographed in the prior art manner, using an anamorphic lens to produce 50% horizontally compressed anamorphic camera film frame images (aspect ratio of about 1.175 to 1). During processing to produce a release print, another anamorphic lens is used to produce 36.5% vertically compressed anamorphic release print film frame images (aspect ratio of 1.85 to 1) of the camera film images. An anamorphic projection lens is used in a motion picture theater to horizontally expand the projected images by about 27% (to an aspect ratio of 2.35 to 1).

  • Patent number: 4980762
    Abstract: An image processing system provides the capability of extracting three dimensional motion information from two dimensional images. The image processing system achieves such extraction by analyzing selected image points. The selected image points correspond to the projection of points on a three dimensional object. The object is moving over time (i.e. translating and rotating with respect to the imaging device). The selected image points are processed in parallel by a plurality of processors to first determine the translational velocity. Next, the rotational velocity of the patch is determined. Lastly, the relative depth of each image point is determined in light of the previously determined translational and rotational velocity. The image processing system accomplishes this task by using an imager and a processing means. The system has potential applications in filming and in robotics.

  • Patent number: 4540255
    Abstract: A photographic method and apparatus for producing a motion picture including moving a film unit in one direction and the optics system along an arcuate path generally laterally thereto so as to produce a plurality of images on the film unit. The camera utilizes means for intermittently moving the film unit, such as a film card, in a first direction with the image produced in sequence in a plurality of parallel, arcuate rows generally laterally of the first direction. Alternate rows of images are produced along a first lateral direction while intervening rows thereof are produced along a second lateral direction opposite to the first one.

  • Patent number: 4477160
    Abstract: A method is described for producing and projecting a theater quality entertainment motion picture, by photographing and then projecting the motion picture on a screen, which creates an unusually vivid impression of realism. The film frames have a resolution of over 40 line pairs per milimeter, and each frame has an area of at least 0.36 square inch, which creates more then 10 million pixels per frame on the film and on the screen. The illumination level on the screen is at least 15 foot lamberts. The film frames are photographed and projected at a predetermined constant rate of more than 50 frames per second, such as 60 fps. The high resolution and light level, combined with the unusually high frame rate, has been found to produce an unusually vivid impression of realism.

  • Patent number: 4295266
    Abstract: The method presented may be utilized in manufacturing CMOS integrated circuits either in an isoplanar or in a LOCOS process. The method entails the simultaneous formation of the well region with the oxide isolation regions by a drive-in diffusion which is conducted in a dry oxygen ambient. The utilization of the process insures that compounds of silicon, nitrogen and oxygen will not be present in the bulk silicon where they can effect the quality of gate oxides which are subsequently formed.
