First Claim
Patent Images
1. A method for configuring an imaging system comprising:
- obtaining a random sample of area coverage representations, an area coverage representation defining a distribution of output combinations for the imaging system;
grouping the obtained area coverage representations into a number of groups based on estimated colorimetry for the imaging system;
determining a selected area coverage representation for each group that modifies one or more estimated imaging attributes; and
generating a color mapping from an input color space to an area coverage representation space for use by the imaging system based on a color gamut for the random sample and the selected area coverage representations.

Abstract
Examples of a method and a system for configuring an imaging system are described. These examples involve obtaining a random sample of area coverage representations and grouping these by an estimated color, such as a colorimetric value. In each group a selected area coverage representation is determined with respect to one or more imaging attributes. A color gamut based on the random sample and the selected area coverage representations are used to generate a color mapping from an input color space to an area coverage representation space for use by the imaging system.

11. Apparatus for configuring an imaging system comprising:
-
a color estimator arranged to access a data model representative of the imaging system and to determine, based on the data model, a color estimate of an area coverage vector, the area coverage vector defining a distribution of output combinations for the imaging system; a sampler arranged to obtain a random sample of area coverage vectors; and a color mapping controller arranged to; access a random sample from the sampler; use the color estimator to group area coverage vectors in the random sample into color groups; select an area coverage vector in each color group based on a comparison of one or more imaging metrics for the group; and determine a color mapping from an input color space to an area coverage vector space for use by the imaging system based on a volume of available colors for the random sample and the selected area coverage vectors. - View Dependent Claims (12, 13, 14)

15. A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon, which, when executed by a processing system, cause the processing system to:
-
obtain a random set of area coverage representations, determine a color estimate for an imaging system in the color space for each obtained area coverage representation; determine a sub-space from a plurality of colorimetric sub-spaces that is associated with each color estimate; determine a set of attribute estimates for each obtained area coverage representation; select an area coverage representation in each sub-space that modifies the set of attribute estimates; determine a color gamut based on the set of random area coverage representations; and generate a color mapping from an input color space to an area coverage representation space for use by the imaging system based on the color gamut and the selected area coverage representations.
