First Claim
1. An electronic system for generating a modified image from an original image comprising:
- a plurality of input devices, each for providing electronic color pixel representations of original images;
a storage device for storing a plurality of color transform definitions, each transform definition representing an input/output relation for color values;
a user interface manipulable by a user to select multiple transform definitions;
a transform composer for composing the user-selected multiple transform definitions into a composite transform definition, said composite transform definition being equivalent to the sequential application of the multiple transform definitions; and
an image processor transforming the colors of the electronic color pixel representation of the original image through a single application of the composite transform definition, thereby generating a modified image.

Abstract
A method and apparatus for generating a modified electronic image combines multiple image transforms into a single composite transform, and then modifies the electronic image in accordance with the composite transform. The composite transform includes sample values sequentially modified in accordance with each of the multiple image transforms being combined. The method and apparatus further provides a user interface allowing a user to select individual transforms for composition. The use of a composite transforms allows a user to interact with the image processing system more quickly and interactively while obtaining a desired modified image.
