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 • Presenting all of the above in the desired resolution and aspect ratio
