Abstract
We describe and claim a film mode judder elimination circuit and method. A film mode detector detects a film mode in a video signal. A judder eliminator eliminates judder by dynamically transitioning from one field rate, e.g., 60 Hz, to another field rate, e.g., 48 Hz or 72 Hz, responsive to the detection. The transition between the one and another field rate may occur during the vertical blanking period to avoid flicker.
