Flare and dimming rates are calculated for a current frame in the video. If a flare rate threshold is exceeded, an intensity of the backlight is limited to a predetermined flare rate. If a dimming rate threshold is exceeded, the backlight intensity is limited to a predetermined dimming rate. The limitations are applied, for example, on an element-by-element basis. In the event of a scene change, the limitations do not need to be applied. A forward modulation signal is calculated by taking into account any applied backlight limitations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Temporal filtering of video signals","description":"A process for reducing noise and temporal artifacts (e.g. walking LEDs) on a dual modulation display system by applying temporal filtering to rear modulation signals of a sequence of video frames.
