Systems and Methods for Mitigating Visible Envelope Effects

摘要

Systems and methods in accordance with embodiments of the present invention are provided to compensate for the envelope effect that appears to an end user as a result of the sampling and digital processing of near-Nyquist frequency components of a video information signal. Embodiments of the present invention improve image quality by effectively nullifying gamma correction in areas where the envelope effect exists, enabling the human eye to perceive the displayed signal without the envelope effect.
