Abstract

The invention discloses a flashlight illumination brightness adjusting method, a flashlight illumination brightness adjusting device and a mobile terminal. The method comprises the steps of after the mobile terminal is in an electric torch mode, monitoring whether a preset physical button is triggered; if the physical button is triggered, acquiring button information which corresponds with the physical button; and based on the button information, adjusting the current illumination brightness of the flashlight on the mobile terminal. The flashlight illumination brightness adjusting method can simply and quickly realize adjustment for illumination brightness of the flashlight so that a user can effectively reduce electric energy consumption without illumination range reduction according to the electric energy state of the mobile terminal, thereby better prolonging standby time of the mobile terminal and furthermore improving user experience.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of terminals, and in particular, to a method and device for adjusting the lighting brightness of a flashlight, and a mobile terminal. Background technique [0002] With the improvement of science and technology, mobile terminals such as mobile phones and tablet computers have more and more functional applications. For example, they can be used as navigation tools for users to locate and navigate, as playback tools for users to play music or videos, and as camera tools for The user takes a picture or takes a video, etc. [0003] When the mobile terminal is used as a camera tool, in order to be able to take better pictures, the manufacturer usually sets a flash in the mobile terminal to supplement the brightness required for taking pictures when necessary. Since the shooting function is only one of the functional applications of the mobile terminal, if the flashlight is only used to ...
