description A system and method for enhancing resolution in a video image includes acquiring a relatively low resolution video signal and applying a peaking function and analyzing the peaked signal to identify potential edges. The low resolution signal is then upconverted to a higher resolution format. Actual edges in the image are detected and linked in the higher resolution format, and a luminance transition improvement function is applied to the edges to sharpen the image. Analysis of the image while at low resolution reduces computation time, yet still produces a high quality output image.
