Abstract

An embodiment of the present invention provides a supplementary light driving method, a supplementary light circuit, and a mobile terminal. The method includes: when using a camera for image acquisition, detecting the setting parameters of the supplementary light; controlling the backlight drive circuit to output through the drive signal The channel outputs a driving signal with a current value corresponding to the setting parameter to the supplementary light, so that the supplementary light emits light under the driving signal. The embodiment of the present invention can improve the shooting performance of the mobile terminal.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for driving a supplementary light, a supplementary light circuit and a mobile terminal. Background technique [0002] With the continuous improvement of the camera performance of the mobile terminal, the photographing function of the mobile terminal is also becoming more and more powerful. In practical applications, users may use mobile terminals to take pictures under different lighting conditions, for example: take pictures at night or in poor light environments, and when taking pictures in these scenes, it is often difficult to obtain the ideal image due to underexposure. shooting effect. At present, in order to improve the shooting effect, some mobile terminals usually add a supplementary light (for example: LED supplementary light), which is used to increase the supplementary light when shooting, so as to achieve the purpose of improving the shooting effect....
