摘要： A camera module includes a camera, a light emitting unit, a circuit board. The camera is mounted on the circuit board and having an optical axis. The light emitting unit is disposed on the circuit board which emits a light beam forming a batwing-shaped luminous intensity distribution. The batwing-shaped luminous intensity distribution has at least two peaks of maximum luminous intensity. The optical axis of the camera is arranged at a position between the at least two peaks of the batwing-shaped luminous intensity distribution. The camera module emits a uniform light for enhancing authenticity of the image and increasing the reliability of the recognition system.
