Driver adventures for a 1999 webcam
There is a lot you can do to improve the quality of the image. This camera has a very early CMOS sensor, which suffered from huge pixel-to-pixel variation. By characterizing each pixel (which you can do by taking dark field and flat field images), you can correct for this variation, and get an image that looks much less noisy. There are also various algorithms to undo the Bayer filtering, with tradeoffs between sharpness, color accuracy and performance.
