Definitions • Image state • The degree to which image data has been constrained or purposed to a particular visualization mechanism, as compared to the degree to which the image data has been retained unaltered with respect to its capture condition Concepts of scenereferred, originalreferred, and outputreferred image state as shown in ISO CD 22028-1-Part 1 ICC workflows include both Actual Output Referred (a particular visualization device) and Reference Output Referred (e.g., SWOP) T2B - Color Management A.

Definitions • ‘Scene-Referred image data’ (SR) • Image data that unambiguously encodes the spectral reflectances of the scene (including scene-capture tristimulus encodings) • A scene-referred image would be encoded using a very large gamut, high dynamic range color encoding specification • ‘Original-Referred image data’ (OR) The idea of image state is intended to be • Image data useful that unambiguously in thinking about encodes two concerns: a captured computer- 1.“What processing has been applied to this image?” 2.“How should I sequence my workflow to maximize color fidelity?” • Output-referred image data that is color-rendered to a standardized (i.e., minimize the need to estimate colors)? generated or hardcopy original • 'Reference-Output-Referred image data' (ROR) output (i.e., an output that is defined through an ideal specification - a precise, arbitrary, output definition that may or may not be realizable) • 'Actual-Output-Referred image data' (AOR) • Output-referred image data that is color-rendered to a specific, particular, realizable device, e.g., encoding the intended color appearance of an image as it is to be printed to a particular printer T2B - Color Management A.
