The calibration target includes at least one color reference region illuminated by a light source having a distribution of frequencies that cycles over a fixed time period. The calibration images are captured over a calibration period that is greater than or equal to the fixed time period over which the distribution of frequencies cycles. Each of the calibration images is associated to a time identifier. A color balance adjustment is calculated for each of the calibration images, for forming a time-dependent color spectrum model of the color balance adjustments. The color spectrum model models changes in the light source over the fixed time period. In one embodiment, a subject image of a subject is captured for a determined exposure time. In the subject image, the subject is illuminated by the light source. Exposure time data is associated to the subject image. At least one subject color balance adjustment is calculated for the subject image from the exposure time data and the color spectrum model."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibrating color for an image","description":"Calibrating color (such as adjusting color balance) for an image may include capturing a set of calibration images of a calibration target.
