Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
There is provided a kind of camera power consumption control method and mobile terminal for the problem of present invention is directed to existing.
First embodiment
Referring to Fig. 1, the first embodiment of the present invention provides a kind of camera power consumption control method, applied to a movement eventually
End, wherein, mobile terminal can be smart mobile phone or tablet personal computer etc.；Mobile terminal includes multiple for detecting mobile terminal
The sensor of currently used scene, the camera power consumption control method includes：
Step 101, the opening of camera is monitored.
Specifically, camera can be front camera or rear camera；Can be by monitoring that user opens camera
Or camera function is called by other applications, determine the opening of camera.
Step 102, when monitor camera be in opening when, obtain sensor current induced signal, according to work as
Whether preceding induced signal judges camera currently in state of taking pictures；
Under normal circumstances, user has many opening cameras but untapped scene, such as when taking pictures out of doors, uses
Clapping in time of the photo to before taking a photo at family, it is likely that camera can not be closed, and this process may
It is time-consuming longer, and consume substantial amounts of electricity.And in embodiments of the invention, when monitoring that camera is in opening,
The usage scenario of mobile terminal can be detected by sensor, and judges camera currently whether in shape of taking pictures according to induced signal
State, is easy to mobile terminal to carry out regulating power consumption.
Step 103, when judged result is no, instruction is turned down to camera output power consumption.
Wherein, when according to the induced signal of sensor judge mobile terminal be not presently within take pictures state when, to camera
Power output turns down signal, to save the electricity of mobile terminal, increases the use duration once charged of mobile terminal.
Alternatively, in the above embodiment of the present invention, sensor includes being used to detect the sense of the display screen of mobile terminal
Light quantity and with objects in front apart from first sensor, first sensor is arranged at end face where display screen, wherein step
102 include：
Obtain the first induced signal of first sensor；
When the distance between object and first sensor being arranged at according to the judgement of the first induced signal in front of display screen
When sensitive volume less than the first default value and first sensor is less than the second default value, determine that camera is not presently within bat
According to state.
Specifically, first sensor is for carrying out light detection and the sensor apart from detection to environment, can detect simultaneously
Place sensitive volume and with external object close to distance.First sensor is arranged at end face where display screen, first sensor
Sensitive volume be to represent the sensitive volume of display screen, represent display screen and external object with the distance of external object
Distance.When the first induced signal according to first sensor, the object and first sensor (display screen in front of display screen are judged
Curtain) the distance between be less than the sensitive volume of the first default value and first sensor (display screen) and be less than the second default value
When, determine that camera is not presently within the state of taking pictures, wherein, the distance between object and display screen in front of display screen
Less than the first default value, i.e., when display screen is obscured by an object, wherein, the object blocked is likely to be transparent substance, and saturating
Bright object has no effect on camera and taken pictures, such as user's handheld mobile phone, which is placed in behind glass, to be gone to take pictures, it is thus impossible to only lead to
The Distance Judgment camera crossed with external object is not in the state of taking pictures；And the sensitive volume of display screen is less than the second default value
When, i.e., display screen is obscured by an object or under dark state, and display screen be in dark state under camera not
Certain influence camera is taken pictures, and therefore, the sensitive volume of display screen also can not be not in shape of taking pictures separately as camera
The basis for estimation of state.Therefore, display screen need to be met simultaneously is less than the first default value and sense with the distance between display screen
When light quantity is less than the second default value, it may be determined that camera is not in the state of taking pictures.
Alternatively, in the above embodiment of the present invention, sensor includes optical sensor, and optical sensor is arranged at camera
On, wherein step 102 includes：
Obtain the second induced signal of optical sensor；
When the sensitive volume that optical sensor is judged according to the second induced signal is less than three default values, determine that camera is worked as
Before be not in the state of taking pictures.
