[0058] An embodiment of the present invention provides a method for controlling camera flash, which is applied to a mobile terminal. figure 2 As shown, the control method includes:

[0059] Step 201: Obtain a photographing and flashing instruction input by a mobile terminal user.

[0060] The photographing flash instruction may be an instruction control by the user's touch screen input, gesture input, or voice input, so as to instruct the flash operation of the mobile terminal.

[0061] Step 202: If the photo synchronization flash application mode in the mobile terminal is activated, then according to the photo flash instruction, send a first synchronization instruction to a target mobile terminal wirelessly connected to the mobile terminal.

[0062] Wherein, the predetermined flashing time of the flashlight in the target mobile terminal is indicated in the first synchronization instruction.

[0063] In this step, there must be a prerequisite for sending a synchronization c...

Abstract

The invention provides a photographing flash control method and a mobile terminal. The method comprises the steps as follows: a photographing flash instruction input by a mobile terminal user is acquired; if a photographing synchronous flash application mode in the mobile terminal is in an activated state, a first synchronization instruction is sent to a target mobile terminal connected with the mobile terminal wirelessly according to the photographing flash instruction, the first synchronization instruction indicates preset flash time of a flash lamp in the target mobile terminal; when the preset flash time is up, the flash lamp of the mobile terminal is controlled to flash to be synchronized with flash of the target mobile terminal, and the photographing quality at night and in environments with dim light is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for controlling a camera flash and a mobile terminal. Background technique [0002] With the significant improvement of camera performance on mobile terminals, more and more users are used to taking pictures in various scenes, but the image quality is not very good at night and in low-light environments. The flashlight is used on the terminal to flash at the moment of taking a photo, so as to improve the shooting quality. [0003] At night and in low-light environments, because the brightness of the flashlight of the terminal device is limited, even if the flashlight is turned on, the brightness of the flashlight is far below the daytime level, resulting in poor image quality. If a flashlight with higher brightness and a flashlight driver with stronger driving capability are to be used, it will cause serious problems in terms of heat dissipation, power co...
