As shown in Figure 1, the embodiment of the present invention provides a kind of power-saving method of mobile terminal, and its specific implementation is as follows:
Step 110: under the camera function opening of mobile terminal, circulation obtains the distance value of range sensor, meets second pre-conditioned, perform step 120 until distance value met for first pre-conditioned duration; Distance value is block the distance between object and described range sensor; First pre-conditionedly refers to that distance value is less than or equal to predeterminable range value; Second pre-conditionedly refers to that the duration is more than or equal to preset durations.
Wherein, circulation time can be regularly (fixed cycle) circulation, also can be irregularly (on-fixed cycle) circulation.
It should be pointed out that distance value is less than or equal to predeterminable range value first pre-conditioned to meet, and distance value to be strictly less than predeterminable range value pre-conditioned to meet first, all in protection scope of the present invention.It is second pre-conditioned to meet that the above-mentioned duration is more than or equal to preset durations, and to be strictly greater than Preset Time pre-conditioned to meet second, also all in protection scope of the present invention the above-mentioned duration.
Step 120: close camera function.
In the embodiment of the present invention, under the camera function opening of mobile terminal, circulation obtains the distance value that range sensor detects, until distance value meet first pre-conditioned duration meet second pre-conditioned time, just close camera function.With prior art, mobile terminal is after unlatching camera function, can always in running orderly compare, the electric quantity consumption that meaningless operating state and additional function (as stabilization function) cause is in owing to decreasing camera function, the electricity of mobile terminal can be saved, thus the stand-by time of mobile terminal is extended.And, due to be distance value meet first pre-conditioned duration meet continue second pre-conditioned time close camera function, first pre-conditionedly just camera function can not be closed because of meeting of distance value short time, the frequent closedown that the situation avoiding closedown by mistake causes is opened, and improves stability and practicality.
In above-mentioned steps 110, if regularly obtain the distance value of range sensor detection, its cycle can set according to practical service environment, or sets based on experience value.Optionally, the cycle that arranges is for [500 milliseconds, 15 seconds].User can select according to the periodic regime provided.
In order to determine that distance value met for first pre-conditioned duration and meets second pre-conditioned, recording distance value is needed to be less than or equal to the duration of (or being less than) predeterminable range value, the method of record has multiple, enumerates below but does not limit two kinds of implementations:
One is that mode by arranging counter realizes: if distance value is less than or equal to (or being less than) predeterminable range value, counter adds 1, until compare distance value to be greater than (or being more than or equal to) predeterminable range value, stops counting, record numerical value, and by counter O reset.

In the embodiment of the present invention, when circulation obtains the distance value of range sensor detection, can be periodic cyclic, also can be irregular circulation.
In the embodiment of the present invention, the duration that distance value is greater than predeterminable range value is when being more than or equal to (or being greater than) preset durations, just judge to need to open camera function, automatically the operating state before can not only recovering camera, and avoid because distance value is only greater than predeterminable range value in the very short time and open by mistake and open, saving electricity further.
Optionally, the scope of predeterminable range value be (0 millimeter, 20 millimeters].
Optionally, range sensor is infrared distance sensor, also can be other suitable range sensor, etc.
Another implementation is:
Circulation obtains the brightness value of light sensors, until the brightness value obtained is greater than the default brightness value that (or being more than or equal to) mate with photoenvironment, judgement needs unlatching; Wherein, the brightness value of brightness value environment residing for mobile terminal.
Wherein, the default brightness value that different photoenvironments is corresponding different.Such as, daytime fine day photoenvironment correspondence to preset brightness value be 100 luxs, the default brightness value corresponding for the cloudy day on daytime is 10 luxs, is 50 luxs for dim indoor on daytime for default brightness value.It should be pointed out that and can also think that dim indoor on daytime, the inferior similar scene of light at night belong to same photoenvironment, for they arrange identical default brightness value.
Wherein, the determination mode of current light environment has multiple, such as, can under mobile terminal operating state or under the state of camera function unlatching, according to the brightness value determination current light environment that optical sensor detects in real time, concrete: the sampled point choosing predetermined quantity from the brightness value of light sensors according to pre-defined rule, to the brightness value averaged of these sampled points, according to this mean value determination current light environment; Or according to choosing the continuous print brightness value of predetermined quantity, the brightness value determination current light environment maximum according to wherein number of repetition, etc.
The embodiment of the present invention, when circulation obtains the brightness value of light sensors, can be periodic cyclic, also can be irregular circulation.
Optionally, optical sensor is ambient light sensor, also can select other suitable optical sensor.
The implementation of above-mentioned steps 120 has multiple, and optionally, the implementation that step 120 is concrete can be: control mobile terminal and enter resting state, or,
Terminate the process of camera function; Or,
Hang up the process of camera function.
