COLOR MAPPING

摘要

A method for color mapping is disclosed. A color mapping is generated based on an imaging model and a color model for an imaging device. The imaging model allows a set of perturbations to be modelled. A set of metamers is determined for one or more colors. For each metamer, at least the imaging model is used to estimate a color output with at least one modelled perturbation. The color outputs are used to select a Metamer from the set to be used for the color mapping.

1. A method comprising:
accessing an imaging model for modelling perturbations of an imaging device; obtaining parameters for at least one color model, the color model indicating a color gamut for the imaging device in a first color space; and determining a color mapping to a second color space for at least one sampled color in the color gamut by:
computing a set of metamers matching the sampled color, each metamer representing a color value in the second color space;for each metamer in the set of metamers, applying at least the imaging model with one or more perturbations to estimate a color error associated with the one or more perturbations; andselecting a metamer for the sampled color based on the set of estimated color errors, wherein the metamer is used, in the second color space, as a color output for the sampled color in the color mapping.
