METHODS AND APPARATUS FOR PROVIDING VIDEO STILL FRAME AND VIDEO CAPTURE FEATURES FROM INTERLACED VIDEO SIGNALS

摘要

Methods and apparatus for reducing the artifacts associated with still fra me display and video capture of interlaced video are provided. Tuner 100 receiv es an interlaced video signal having an image frame with first and second fields. Motion detector 55 detects whether motion is present between the first and second fields. Memory 40 stores one or both of the fields for processing when motion is detected. Processor 30 processes the stored field(s) to provide an image frame with reduced artifacts. Various processing techniques are provided to generate the image frame from the stored field(s), without duplicating the stored field for use as the oth er field. Memory 40 stores the image frame. If motion is not detected, the first and second fields are both stored to provide the image frame. The stored image frame can then be continuously displayed to provide still frame display, or can be captured fo r subsequent use.
