Abstract
A system for simulating a depth of field of an image includes a microprocessor coupled to a graphics input device, an input device, an output device, and a memory. The microprocessor executes a camera simulation application to accomplish depth of field "focusing" of the image in a two dimensional space by simulating defocusing and light fall-off effects similar to those generated by a camera lens. The input device specifies a variety of camera-like controls and parameters in response to user instruction.
