DScaler 4 is a piece of software that captures video, processes it, and scales it for presentation on a projector or computer monitor.

DScaler implements highly sophisticated algorithms that work in real-time to provide PC owners with image quality matched only by very expensive equipment.

DScaler performs a variety of functions:

Grabbing video from a DVD player, game console, laserdisc, or VCR in a reliable fashion, in either analog or digital form;
Deinterlacing video source, such as sports and news produced with a video camera, as well as console games;
Detecting and removing 2:2 pulldown (PAL) and 3:2 pulldown (NTSC) for movies and filmed television programs;
Reducing video noise on analog sources;
Automatically calibrating video capture cards for optimal brightness, contrast and color;
Manipulating video through gamma, sharpness and other filters;
Viewing still images;
Reducing judder and other video timing anomalies; and
Presenting all of the above in the desired resolution and aspect ratio.
