Abrégé

The present application related to a camera system and a camera fill light method. The camera system establishes a wireless communications connection with a fill light, captures an original image by a camera in the camera system, and then transmits a first test light signal to the fill light such that a first flash is performed by the fill light. The camera captures a first light source image during the first flash period of the fill light. A fill light controller in the camera system compares differences of the brightness or the chroma of different image information and, after determining the present location of the fill light, calculates a dislocation result of the present location of the fill light and the best placement location of the fill light. The camera system yields the dislocation result to the photographer via a notification message.
