Abstract
Imaging systems may be provided with image sensors for capturing information about incident light intensities in the visible and infrared bands of light. The means of capturing information about visible light may be unintentionally and undesirably influenced by infrared light. Similarly, the means of capturing information about infrared light may be unintentionally and undesirably influenced by visible light. Storage and processing circuitry may correct for the undesired influence of infrared and visible light on the signal data from the visible and infrared sensors, respectively. The correction may be determined or chosen based on a detection of the illuminant type of the imaged scene. The correction may alternatively be universal, and applicable to images of scenes illuminated by any illuminant.
