Embodiment Construction

[0020] refer to figure 1 , figure 1 It is a flow chart of an embodiment of the flashlight control method of the mobile terminal of the present invention. The flashlight control method of the mobile terminal of the present invention includes

[0021] In step S11, when the camera function of the mobile terminal is turned on, the light intensity required by the camera for normal exposure is obtained. The light intensity required for the normal exposure of the camera can be pre-stored in the mobile terminal and called directly when needed.

[0022] In step S12, the light intensity of the current environment is acquired. The light intensity of the current environment is generally acquired by an ambient light sensor.

[0023] In step S13, the light intensity of the current environment is compared with the light intensity required by the camera for normal exposure.

[0024] In step S14, the opening and brightness of the flashlight are controlled according to the comparison resul...

Abstract

The invention discloses a mobile terminal and a flash lamp control method. The flash lamp control method comprises the following steps: when the shooting function of the mobile terminal is started up, acquiring the light intensity required by normal exposure of a camera; acquiring the light intensity of the current environment; comparing the light intensity of the current environment with the light intensity required by the normal exposure of the camera, and calculating the differential value between the light intensity of the current environment and the light intensity required by the normal exposure of the camera if the light intensity of the current environment is not within a range of the light intensity required by the normal exposure of the camera; and controlling the start-up brightness of a flash lamp according to the differential value. By utilizing the method, the intensity of the flash lamp can be calculated according to the light intensity of the current environment, so that the overexposure is avoided, and the current consumption is also reduced.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a mobile terminal and a flashlight control method thereof. Background technique [0002] With the development of science and technology, mobile terminals such as mobile phones have gradually become necessities in people's lives. Most of existing mobile terminals such as mobile phones have light sensors and camera functions. The light sensor is generally used to detect the ambient light intensity and whether the screen is close to the face during a call. And when taking pictures, generally all can be divided into turning on the flashlight and turning off the flashlight, so the problem of excessive light intensity often occurs, and wastes the power of the mobile terminal. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a mobile terminal and its flashlight control method, which can calculate the flashlight intensity ac...
