Problems solved by technology
The preview effect of the first method will be better, but the power consumption is high. The brightness of the backlight changes with the ambient light when previewing the second method, taking into account the effect and power consumption, but the function of automatically adjusting the backlight must be enabled on the mobile phone. Use, when the user turns off the automatic dimming function, the backlight of the preview will not change with the ambient light

Embodiment Construction
[0017] In order to facilitate the understanding of those skilled in the art, a preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings to describe the present invention and its possible effects and advantages.
[0018] attached figure 1 It is a schematic flow chart of an intelligent dimming method during camera preview according to an embodiment of the present invention.
[0019] An intelligent dimming method during video preview, applied to a mobile terminal with a camera module and a photosensitive module, comprising steps:
[0020] Step 101 , triggering the preview function of the camera module when receiving a camera command; the camera enters a working state by accepting a user's button or touch operation command, and displays a preview interface.
[0021] Step 102, judging whether the photosensitive module is turned on;
[0022] It can be judged by obtaining the status value of the status register. ...

The invention discloses an intelligent dimming method during image pickup preview and a mobile terminal. The method comprises the following steps that the preview function of a camera module is triggered when an image pickup instruction is received; whether a light sensing module is opened or not is judged, and if the light sensing module is opened, the back light brightness of a screen is regulated according to comparison results of the first screen back light grade number provided by the light sensing module and the second screen back light grade number provided by the camera module; and if the light sensing module is not opened, the screen back light brightness is regulated according to the screen back light grade number provided by the camera module. The mobile terminal adopting the method comprises the camera module, the light sensing module, a judgment module, an obtaining module, a comparison module and a regulation module. The intelligent dimming method during the image pickup preview and the mobile terminal provided by the invention have the advantages that the screen back light brightness can be automatically regulated according to the ambient environment during the camera preview interface entering no matter whether the light sensing function of the mobile phone is started or not, and intelligence, high efficiency and energy saving are realized.
Description
technical field [0001] The invention relates to an intelligent dimming method and a mobile terminal during camera preview. Background technique [0002] There are two main ways to set the backlight of the current mobile phone after entering the camera: 1. Fix a backlight brightness, such as setting it to the maximum backlight; 2. The backlight changes with the backlight of the mobile phone display. The preview effect of the first method will be better, but the power consumption is relatively high. The brightness of the backlight changes with the ambient light when previewing the second method, taking into account the effect and power consumption, but the function of automatically adjusting the backlight must be enabled on the mobile phone. Use, when the user turns off the automatic dimming function, the backlight of the preview will not change with the ambient light. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the pr...
