Abstract
A system for creating high resolution video images for later use in printing or the like. The operator draws with a stylus on a touch tablet (28) and video signals are processed to produce a high resolution image corresponding to what is drawn, the signals being stored in a high resolution store (25). While the processing of the signals progresses certain signals are copied to a lower resolution viewing store (26) and these signals read to a display (27) where the image can be viewed by the operator. In one example the store (25) is notionally divided into areas and when the signals representing a stroke drawn by the operator are present in an area the whole area is copied to the viewing store. Typically about four areas need to be copied in a frame period so the stroke drawn by the operator can be seen as he is drawing it. The image on display (27) may be a low resolution version of the whole image or a high resolution version of part of the image.
