internal projector scaler vs external/quadscan

209.246.90.37

Posted by magman on May 8, 2001 at 16:19:42

I have a mitsubishi X-100/XGA (business version of VL-2000) that is around 3 years old. I am wondering if a external scaler like the quadscan would be better than the build in scaler. The scaler chip is from Genesis Microchip and might be the gmZ3. Is there that much a difference? Especially if something like the quadscan also utilizes some Genesis scaling chip?

The projector has zoom/image capture/native size, which allows me to freeze a frame/magnify it so that I could examine individual pixels as to how it was derived relative to the native image. I obviously don't see nearest neighbor, but as far as it utilizing superscaling technology, I don't know.

I know the de-interlacing is terrible on projector, with its pixel downshift(or upshift) method of doubling, and no motion adaptive/compensation. Plugging in the DVDO Iscan Pro in between is a big plus, not just on reverse telecine, but also on video source, with its selective bob/weave/blur and scaling de-jaggling low res diagnol lines(VHS source,) which has obvisous pixel jaggles @230 steps/frame, to close to 480steps/frame.

Any help would be useful.
