ABSTRACT
All successful color imaging systems employ some form of color management. In chemical and other analog-based imaging systems, color management may be implemented in various ways, including equipment calibration, chemical process control, and operator-controlled or automated color-printing adjustments. In digital imaging systems, color management is generally implemented using software designed specifically for that purpose. The successful implementation of digital color management depends on a number of factors, including the use of appropriate device characterization methods and suitable mathematical techniques for forming and applying image-processing transformations. In addition to the selection of a color management paradigm appropriate for a given application, the successful implementation of digital color management requires the use of an appropriate method for digitally encoding color. Most digital images can be broadly categorized into two types of image states: unrendered and rendered. Images in an unrendered image state are directly related to the colorimetry of real or hypothetical original scenes.
