Abstract
A method of simulating airbrushing of an image electronically comprises generating a set of pixel values from a stored set. The pixels define the area of an airbrush and the color content is modified by selecting sets in sequence, then combining the image pixel content with the pixel value and a unit amount of brush color. The pixel values are generated by dividing the sequence into sets and recording the number of occurrences of each pixel coordinate in a set. The brush may be a single color or contain pixels of many different colors when defined by another image.
