Abstract
Systems, methods, and computer readable media to identify the operating characteristics of a multi-LED flash module for use with a image capture device are described. Flash modules having multiple LEDs have been found to exhibit large module-to-module variation in the light spectrum they emit. It has been determined that such variations make defining a 'golden module' impractical. To overcome this and other issues, techniques to characterize the operational behavior of a flash module having multiple LEDs using easily obtained measurements are disclosed. Such characterizations permit the characterization of each flash module to account for the particular lighting capability of its specific LEDs during image capture operations.
