Up-Res – The process which increases the size, or number of pixels used to represent an image by interpolating between existing pixels to create the same image on a larger format. There is no implied change of vertical scan rate. Despite its name, the process does not increase the resolution of the image; it just spreads the same over a larger canvas. The quality of the result depends on that of the interpolation. Speed is an issue for realtime work, as good quality requires a large amount of processing – which increases with the picture area.
