[0020] Such as figure 1 As shown, it is a flow chart of the steps of the control method of the flashlight in the first embodiment of the present invention, and the control method includes:

[0021] Step 101 , acquiring a focusing result of a camera of the mobile terminal on an object to be photographed when the mobile terminal detects a photographing instruction.

[0022] In this step, when the mobile terminal detects the photographing instruction, it can obtain the focusing result of the object to be photographed by the camera of the mobile terminal. Specifically, the focusing result may include that the object distance and the image distance of the camera lens have a preset conjugate relationship and that the object distance and the image distance of the camera lens do not have a preset conjugate relationship, that is, include focusing success and focusing failure.

[0023] Specifically, when the camera is shooting, when the lens satisfies the formula XX'=FF', that is, when...

[0033] Such as figure 2 As shown, it is a flow chart of the steps of the control method of the flashlight in the second embodiment of the present invention, and the control method includes:

[0034] Step 201, acquiring a focusing result of a camera of a mobile terminal on an object to be photographed when the mobile terminal detects a photographing instruction.

[0035] In this step, when the mobile terminal detects the photographing instruction, it can obtain the focusing result of the object to be photographed by the camera of the mobile terminal. Specifically, the focusing result may include that the object distance and the image distance of the camera lens have a preset conjugate relationship and that the object distance and the image distance of the camera lens do not have a preset conjugate relationship, that is, include focusing success and focusing failure. When the focusing result is that the object distance and the image distance of the camera lens have a preset co...

[0042] Such as image 3 As shown, it is a schematic structural diagram of the mobile terminal in the third embodiment of the present invention, and the mobile terminal includes:

[0043] The first acquisition module 301 is configured to acquire the focusing result of the object to be photographed by the camera of the mobile terminal when the mobile terminal detects the photographing instruction;

[0044] The first control module 302 is configured to control the flashlight of the mobile terminal to reduce the brightness when the focusing result is that the object distance and the image distance of the camera lens do not have a preset conjugate relationship.

[0045] In this way, when the mobile terminal detects a photographing instruction, the first acquisition module acquires the focusing result of the object to be photographed by the camera of the mobile terminal, and when the focusing result is that the object distance and image distance of the camera lens do not have preset...

Abstract

The invention provides a flashlight control method and a mobile terminal, wherein the control method comprises the following steps of: obtaining a focusing result of an object to be shot by a camera of the mobile terminal when the mobile terminal detects a shooting instruction; and controlling a flashlight of the mobile terminal to reduce brightness when the focusing result is that the object distance and the image distance of a camera lens do not have a pre-set conjugated relationship. By means of the embodiment of the invention, the problems of skin burns or security incidents easily due to flashlight shooting when the mobile terminal is closer to a shot or photographed object can be effectively avoided; and the user experience is improved.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a method for controlling a flashlight and a mobile terminal. Background technique [0002] With the continuous development of mobile terminals, photographing and video recording have become standard functions of the mobile terminal, and in order to enhance the effect of photographing and video recording, a flash light has also become a standard configuration of the mobile terminal. In addition, as the requirements for photographing effects are getting higher and higher, on the one hand, the operating current of the flashlight is getting higher and higher, making the flashlight brighter; on the other hand, the number of flashlights on the mobile terminal has also changed from one to two. For example, there are two rear flashes on the mobile terminal, or there are one front flash and one rear flash. [0003] However, while the flash significantly improves the effect of taking photo...
