Abstract
Official abstract text for this publication.
The present disclosure related to acquisition of color calibration charts. In at least some examples herein, an image of a calibration color chart is processed. A lighting condition of the color calibration chart may be automatically determined.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: automatically determining, by a processor, a lighting condition of an imaged color calibration chart acquired by an imaging device, including comparing multiple measurements of an optical property at selected spots in the imaged color calibration chart; assessing whether the determined lighting condition corresponds to a selected lighting condition that is appropriate for performing color calibration based on the acquired color calibra…
