Abstract

An illuminating control system for controlling a plurality of illuminating devices is disclosed herein. The illuminating control system includes an image capturing device and a processor. The image capturing device is configured to capture images of an object. The processor is coupled to the image capturing device. The processor is configured to receive the images and determine whether the object is a predetermined object based on the images. If the processor determines that the object is the predetermined object, the processor controls the image capturing device to track the object to obtain a moving condition of the object. The processor turns on one of the illuminating devices correspondingly based on the moving condition of the object.
