ABSTRACT:
An image processing system in which a source patch (35) of pixels is copied from one region of an image to a destination patch (34) of pixels in response to the movement of a stylus (15) over a touch-tablet (16). Each pixel in the destination patch is modified towards the value of its respective pixel in the source patch, and the extent of modification is controlled by brush profile data (36). In one embodiment the source patch 35 and the destination patch (34) are defined in mutually exclusive regions. In another embodiment the source patch and the destination patch are defined in overlapping regions.
