The apparatus and method employ a variety of units, including Laplacian filters, rank value filters, edge detectors, gain units and summation units, to transform an input digitized signal of an image, the transformation being carried out for each pixel independently. The various elements are combined to produce a variety of desired visual effects, e.g. a brush stroke effect, or the appearance of a reflective chrome surface. Further, an apparatus is provided in which a conditioning unit generates a conditioning function, which enables different parts of an image to be combined in accordance with different methods. Thus, a foreground of an image could have the edge content reinforced, whilst the background has brush stroke texture added.
