Abstract: An improved object-based image processing system and method which minimizes and improves predictability and control over regeneration and recalculation time when the user makes changes to operations. Image clips containing bitmaps of object results are stored to minimize repeated application of operations. Partial updates for modified operations are facilitated so that unnecessary regeneration of the entire region of operation is avoided. Greater user control is achieved by permitting the user to designate a temporary background image.

Abstract: A system and method for processing images employs virtual lens objects as image processing elements in a computer-implemented scheme. Each lens object represents one or more image processing operations defined by user-specified lens attributes. The operations may simulate actual physical lens behavior, or they may be abstract operations with no real-world analogs. The user may specify various types of operations for each lens object, and may add, delete, and modify lens objects and lens attributes to experiment with various configurations. The system and method apply the lens objects to a source image to produce a transformed image for output on a screen or printing device.
