Abstract

The invention provides a method for controlling a flash lamp of a mobile terminal and a mobile terminal. A first flash lamp is arranged on the mobile terminal, and the method includes judging whether the first flash lamp is damaged when a flashlight opening instruction is detected; switching on the first flash lamp as a flashlight when the first flash lamp is not damaged; detecting whether the temperature of the first flash lamp exceeds a preset threshold value at preset time intervals; and reducing driving current of the first flash lamp according to a preset step length when the temperature of the first flash lamp exceeds the preset threshold value. Thus, the method for controlling the flash lamp of the mobile terminal can monitor whether the temperature of the flash lamp exceeds the preset threshold value in real time after the flash lamp is switched on as a flashlight, thereby flexibly adjusting the driving current, solving the problem that after the flashlight is used for a long time, the flash lamp is damaged due to too high temperature, and improving usage experience of a user.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a mobile terminal flash control method and the mobile terminal. Background technique [0002] Smartphones have become standard configurations with front and rear cameras, and rear cameras are equipped with at least one flashlight, and more and more front-facing cameras of mobile phones are also equipped with flashlights, which can be used as flashlight auxiliary lighting when the flashlight is always on. However, after using the flashlight function for a long time, the temperature of the flashlight will rise, especially when the driving current is relatively high, it is easy to cause damage to the flashlight, which not only affects the normal use of the user, but also makes the user have to replace the damaged flashlight, which increases the user cost. Contents of the invention [0003] Embodiments of the present invention provide a method for controlling a flash l...
