Abstract
A method for controlling a flash lamp of a camera to provide supplemental light during image-capturing is disclosed. The flash lamp includes a lamp and a position adjusting unit, the lamp being able to track a moving target object in addition to being able to apply spotlighting or wide angle illumination of the object. The method acquires a first brightness value surrounding a target object from a photosensitive unit, compares the value with a preset value and turns on the lamp when the value is less than the preset value. The camera can detect whether the target object is moving; and the lamp can be controlled to move (by the position adjusting unit) to track the moving target object and maintain illumination of it for the image-capture.
