Signal Modification For One Gun Color Tube (e.g., Dot Sequential) Patents (Class 348/709)
  • Patent number: 8368816
    Abstract: A circuit for detecting motion pictures includes a first-stage motion picture detecting unit and a second-stage motion picture detecting unit. The first-stage motion picture detecting unit analyzes a current image frame and a previous image frame to calculate a first motion value associated with the current image frame. The second-stage motion picture detecting unit receives the first motion value, compares the first motion value against an adjusted motion value, and outputs and stores a larger one as a second motion value. The adjusted motion value is a value derived by adjusting an adjacent previous second motion value.

  • Patent number: 5959698
    Abstract: A poly phase filter for converting a sampling frequency of a digital video signal to perform a dot sequential color difference signal conversion operation, the digital video signal including a luminance signal and a color difference signal, the color difference signal including two color difference signal components. The poly phase filter is adapted to generate a plurality of poly phase filter coefficients to be used to process the luminance signal and to process the color difference signal. The poly phase filter is also adapted to process the generated poly phase filter coefficients in units of two to process the color difference signal. Therefore, the present invention has the effect of reducing the hardware size and the associated cost.
