Abstract
Methods and apparatus for reducing the artifacts associated with still frame display and video capture of interlaced video are provided. Tuner receives an interlaced video signal having an image frame with first and second fields. Motion detector detects whether motion is present between the first and second fields. Memory stores one or both of the fields for processing when motion is detected. Processor 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 other field. Memory 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 for subsequent use.
