  • Video processor
    Patent number: 4714958
    Abstract: A video processor receives a video signal and shifts and accentuates the signal in order to increase the apparent depth and resolution of the signal. The circuit operates to accentuate the interface between low luminance and high luminance portions of a video signal as a function of the slope of the video signal. The accentuated signal is also shifted by a slight amount and is then recombined with the original unmodified video signal. The result is substantially improved picture quality with the use of a minimal number of components.
