System and method for eliminating interlace motion artifacts in captured digital video data
First Claim
1. A method for improving digital video data of a target, comprisingcapturing said digital video image data in a plurality of fields;
- comparing interfield differences between said plurality of fields to intrafield pixel differences to detect in said digital video image data an area corresponding to motion of said target;
deleting said image area from one of said fields; and
substituting in said area of said one of said fields an image area functionally related to said image area from another of said fields.

Abstract
Analog video data input is received by a video display adapter of a digital video capture system. Most of the resolution of the captured full interlaced image is retained while eliminating the image shake of fast moving components. A first and second sequential field comprising a full frame of video data are captured and digitized. These fields are then processed to determine areas corrupted by fast movement of components of the image which were captured. In the areas of detected fast movement, an estimate for pels is substituted in one field based upon the other field. Resolution loss is thereby confined to small areas which, due to rapid motion, were not well defined prior to processing.
