  • Patent number: 5002387
    Abstract: An alternate eye 3-d projection system has a projector projecting alternate eye left and right images, has alternating eye 3-d glasses alternating between left and right lens transmissiveness, and has a phase delay unit synchronizing the left lens transmissiveness to left images and right lens transmissiveness to right images. A timing shutter is driven through a mechanical link to the projector primary mechanism at a frequency proportional to the frequency of the transition between images. A sensor outputs pulses according to the rotationally frequency of the timing shutter. The phase delay unit receives the pulses, a multiplier multiplies the frequency of the pulses, a phase lock loop locks on to the frequency and a counter counts the pulses. After a preset delay the counter outputs a pulse. The delay is adjustable. The counter pulse enables a 60 KHz oscillator. The oscillations are counted by another counter and passed to a transmitter.

  • Patent number: 4993828
    Abstract: A camera for producing 3-D motion pictures has "left eye" and "right eye" camera lenses and two corresponding film transport mechanisms. Images to be recorded on films transported by the mechanisms are reflected by semitransparent mirrors and the mechanisms and the mechanisms are arranged so that the mirrors turn the images transversely of the films. Contact prints made from the films can then simply be turned face-for-face to correct for the image reversals due to the presence of the mirrors. The contact prints are then correctly oriented for projection.
