  • 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: 7326911
    Abstract: A system and method of detecting and thwarting the use of unauthorized imaging systems at theatrical performances. Sensors are deployed at a theatrical event to detect a focusing signal and/or the RF signal of an unauthorized imaging device. De-focusing signals are used to disrupt the auto focus system of imaging devices that do not use IR focusing systems. A thwarting signal comprising invisible light frequencies may be combined to produce a thwarting signal that is received by the CCD of an imaging device as white light thereby rendering the recorded image unusable. Emission signatures of imaging devices are stored in a datastore and distributed to users of thwarting systems via a network. Emission signatures are associated with thwarting signals to allow detection and thwarting systems to respond quickly to the use of an unauthorized imaging device.

  • Patent number: 4927261
    Abstract: Method and photographic apparatus for performing motion studies on a moving subject. The moving subject is photographed through a rotating disc having at least one transparent aperture and a plurality of filter apertures covered with filter plates. Opaque regions of the disc separate the apertures from one another. Preferably, miniature spotlights are connected to moving points of the subject that are desired to be studied. Each of the spotlights projects a beam having essentially one selected wavelength to pass through the filter apertures and the filter plates. Incident background light, lighting the subject, is prevented from passing through the filter apertures by virtue of the filter plates. As a result, a photograph produced by the camera includes a series of light-streak images produced by the motion of the spotlights and the light emitted by the spotlights entering the filter apertures. Interruptions in the light-streaks are produced by the opaque regions of the disc.

  • Patent number: 4522475
    Abstract: An apparatus and method for showing motion in a single color photograph in which motion of an object is shown by displaced images of the object in different colors. The scene to be photographed is illuminated by a light source including a plurality of light units emitting light of differing spectral composition. The light units are individually and sequentially activated, the light emitted from all of the units appearing to be emitted from substantially the same location. The flashing of the light units is controlled by a timer. The resulting photograph shows the non-moving objects in a color which is the composite of the spectral composition of all of the light units, typically the natural color. The movement of an object is shown by a spaced series of sharp images of that object in a variety of colors. The color sequence corresponds to the sequence of the flashes of the light units.

  • Patent number: 4498744
    Abstract: There is disclosed a method of producing a photograph of a mobile subject such as a vehicle, in which method a camera is mounted for linear translational movement along a support in a direction parallel with the path of movement of the subject. A motion transmitting operative connection is established between the subject and the camera such that for a linear translational displacement of the subject in said direction there will be a corresponding linear translational displacement of the camera in said direction along said support. The motion transmitting connection may comprise a mechanical connection e.g. via Bowden cable, or an electrical or electronic servo arrangement. To produce a photograph, the subject is displaced linearly in said one direction while making a photographic exposure in the camera, so that the period of the exposure lies within the period of corresponding movement of the camera along said support.

After reversal development, a transparent template having two sets of aligned, spaced-apart cross-hairs is positioned over the film such that the upper set of cross-hairs is aligned with one of the recorded targets. Then, using the lower pair of cross-hairs as a guide, a pin-hole is punched in the unexposed i.e. opaque portion of the frame. This action is repeated for every frame in the film, altering the size of the dot as need be, as the target moves towards or away from the camera.

    Abstract: A method of making and utilizing a composite three layer specially polari motion target film for gunnery practice in which two vectograph films of 90.degree. variance in polarization and a black and white film comprise the composite film and are prepared by image transfer from a normal color movie film of a real world scene including background and target areas made with the target areas painted a color uncommon to the colors in the background. The method includes filtering out background and target areas respectively in image transfer to the respective vectograph films and in utilizing a filter rendering an appropriate gray value to the uncommon color target areas in the image transfer to the black and white film to cause the uncommon color targets to blend in with the background properly in the image obtained from the composite film. The result obtained is a complete motion picture film plus target areas, visible and invisible, of 90.degree.
