ABSTRACT:
The invention provides a method and apparatus for processing digital image data to produce realism-imparting effects such as shadowing, highlighting, color filtering, colored reflections rendering and the like. An image processing apparatus in accordance with the invention includes three independent processing units for processing the Red, Green and Blue components of a supplied set of image-defining signals. The apparatus provides either homogeneous intensity scaling for all three colors or intensity scaling on a color-by-color basis. Means are provided for changing the imparted effects in real time on a pixel-by-pixel basis. Means are provided for using one signal to control the effect imparted on a second signal.
