ABSTRACT:
Methods and apparatus for enhancing the definition of television images in real-time is presented. Television video signals are digitized and processed, preferably through 3-D filtering, to increase the number of pixels per line, horizontal lines per frame, and frames per second and provide an output in progressive-scan format. The system accepts an interlaced scanned image of any transmission standard (NTSC, PAL, etc.), and can be adapted to work on progressively scanned images or digitally stored/transmitted images in real-time or off-line.
