- 10 - ABSTRACT The present invention relates to video signal processors, for example video character generators, which perform anti-aliasing. According to the present invention, there is provided a video signal processor in which signals representing images are subjected to anti-aliasing before display, the generator including means for 1) subjecting such signals to a first, relatively slow anti-aliasing process to produce relatively high quality images and 2) subjecting such signals to a second, relatively fast anti-aliasing process to produce relatively lower quality images; and means for selecting between the first and second processes. This allows a desired balance between operating speed and image quality to be achieved.
