Abstract
A voltage-controlled light diffusing module, a flash lamp module and a controlling method thereof are provided. The voltage-controlled light diffusing module includes a light diffuser, a driving circuit and an information processing unit. The information processing unit receives face information for deciding a driving voltage of the driving circuit, so as to change transmission of the light diffuser.
