  • Method and apparatus for capturing video images
    Patent number: 5367337
    Abstract: Apparatus and method are provided which receive and sample an incoming video image signal asynchronously, and then processes the signal to recover the video image, including video format, for conversion into a preselected video format. The apparatus and methods first sample the video signal using a stable (crystal oscillator) time base clock to reconstruct the frequency of the video signal, i.e., to recover the video format and then using a contrast optimization process to determine the video signal pixel clock rate.
