Abstract
A method and an apparatus are provided for image stabilization for the output of analog-to-digital converters (ADC) and for phase-locked loops (PLL). The digital coding at the output of ADCs and PLLs is filtered by this method and apparatus to eliminate the noise which has contaminated the coding. The noise sources are noise picked up by the cable, system board noise, ADC power and ground noise paths, and switching noise. The differences of energy level of sequential pixels in the ADC and PLL digital outputs used in image displays are used to decide if correction is required. The method of image noise filtering is compatible with programmable circuitry. This allows the method to be tuned for optimal image stabilization.
