Abstract

The mobile terminal provided by the present disclosure includes a terminal body and a control unit. The terminal body is provided with a flash lamp. A zoom lens is provided in an advancing direction of a light of the flash lamp. The control unit is configured to control the flash lamp to switch between a flash mode and a flashlight mode according to an input command. The zoom lens has a plurality of operating states and can converge the light of the flash lamp in at least one operating state. Thus, the mobile terminal can be used as a flash and as a flashlight having a relatively large irradiation distance and further as a flashlight with adjustable irradiation distance.
