Abstract :
The appearance of more limits the performance of high-resolution cathode ray tubes (CRTs). Until now, cancellation circuits have used a small alternating image shift (wobble) to disguise moire, but these circuits introduce other artifacts like flicker. We present a novel solution for suppressing video moire with a specific non-linear filter. Advantages include simple digital video signal processing and negligible degradation of the image quality, even in graphics with very fine detail
