Abstract
The present invention generally relates to the conversion of a picture data in an interlaced format to a progressive format, and more particularly, to an adaptive edge-based scan line interpolation method and apparatus for improving the picture quality in a display system. The present invention provides a method and apparatus for converting interlaced scanning images to progressive images by using simple motion detection procedure and adaptive edge-interpolation. Therefore, the present invention is capable of performing the interlaced-to-progressive conversion with less hardware and buffer cost. Besides, the present invention performs the motion detection by examining the 1-D (one-dimension) pixel array at the adjacent fields. Therefore, the computation of the interlaced-to-progressive conversion of the present invention is less complex than the prior art. Furthermore, the video image of the present invention has a sharper video image with edge preservation and flicker reduction.
