  • Patent number: 5635725
    Abstract: The present disclosure teaches a method and apparatus for use in stabilizing images. The invention operates to sense the position of the image to be stabilized, compare the position of the image to a reference to determine a displacement value responsive thereto and change a correction element located in the conveyance path of the image in response to the displacement value to cause a compensating displacement of the image.

  • Patent number: 5592508
    Abstract: The apparatus and method describes herein shows a system of digitizing analog or digital electronic or optical signals with very high single bit serial digital data streams which digitizing is suitable to automatically adapt the transmission of multiple types of analog and digital signals. The system is especially well suited for allowing the coupling and transmission of signals.

  • Patent number: 5572261
    Abstract: The apparatus and method described herein provides for detecting or measuring the relative timing of the audio and video portions of an audio visual program by inspection of the opening and closing of the mouth of a speaker, and comparing that opening and closing to the utterance of sounds associated therewith.

  • Patent number: 5550594
    Abstract: This invention is a method and apparatus for synchronization of high quality video like signals. Full sync tip to peak white video is digitized in the preferred embodiment along with oversampling and interpolation so that errors are kept to unexpected low levels. The preferred embodiment is described to pass one or more secondary signal with the video signal in a separate parallel but time related path. The use of the input signal for a reference to allow a fixed delay is also shown.

  • Patent number: 5543743
    Abstract: The apparatus and method described herein provides for generating a delayed reference in response to a received reference. The occurrence of a first event in the received reference is detected and a delay period started in response thereto. At the end of the delay period a reset is generated. A delayed version of the received reference is then generated in response to the reset. In addition, a delayed signal is generated to steer a companion delay to the same value.

  • Patent number: 5530483
    Abstract: The apparatus and method described herein shows a system of determining the delay of a delayed version of a sequence of images with respect to a relatively undelayed version. The system operates to take multiple samples of the delayed and undelayed versions at approximately the same sample position on the image and to correlate these samples over multiple image frames to determine which of a plurality of delayed images most closely match a given undelayed image. By knowing which delayed image frame most closely matches a given undelayed image frame it is shown to arrive at a coarse number of frames of delay. A fine delay measurement is achieved by adding a measure of the instantaneous frame to frame delay with respect to a known corresponding feature of the respective video type signals. The invention is also useful for comparing a given image to other images to determine the closest match.

  • Patent number: 5486869
    Abstract: The present invention provides a synchronizing signal separation. In accordance with the present invention, a sync pulse processing circuitry slices a video signal and senses the peaks of the synchronizing pulse. A reference generating circuitry divides the output from the sync pulse processing circuitry into a plurality of reference signals that are compared with the video signal, thereby producing logic level outputs. A sync restoring circuitry combines the logic level outputs to provide precisely reconstructed synchronizing pulses of the video signal. The present invention incorporates different standard functions with superior performance because it may be applied for different types of video signals.
