Abstract
Lighting conditions affect quality of images being captured. In traditional systems, illuminators (light sources) are used to illuminate the objects without considering illumination levels at different zones/sides of an object being photographed. As a result, all illuminators may run at maximum capacity, resulting in wastage of power and compromising efficiency of the system. The disclosure herein generally relates to illumination of objects, and, more particularly, to a method and system for adaptive illumination of objects. The system determines illumination at different zones of the object, and further identifies zones that are not illuminated properly in comparison with a threshold of illumination. Further the system controls intensity of only the illuminators which are responsible for illumination of the zones in which measured illumination is below a threshold of illumination, and increases the intensity by a value determined based on difference between measured illumination and the threshold of illumination, for each zone.
