Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment a part of embodiment that is the present invention, rather than whole embodiments.Based on this
Embodiment in bright, the every other enforcement that those of ordinary skill in the art are obtained under the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
First embodiment
Referring to Fig. 1, Fig. 1 is the flow chart of based reminding method provided in an embodiment of the present invention, and methods described is applied to using sharp
The mobile terminal that light focusing is taken pictures, as shown in figure 1, the method comprising the steps of:
The laser beam that step 101, reception return, wherein, laser beam is the Laser emission assembly transmitting using mobile terminal.
In this step, when described mobile terminal need first to carry out focus function with carry out follow-up take pictures etc. function when, can
Whether totally first to carry out the focusing window detecting mobile terminal, at this moment, described mobile terminal not can be first using Laser emission
A laser beam launched by assembly, and after described mobile terminal uses Laser emission assembly transmitting laser beam, described mobile reception is returned
The laser beam returning, then can use a light power detection circuit or element etc., to detect described in the laser of return that receives
The luminous power of bundle.
Wherein, the Laser emission assembly of described mobile terminal, may refer to the Laser emission that mobile terminal itself is configured with
Assembly, such as carries out, using laser, the Laser emission assembly of the mobile terminal taken pictures or mobile terminal docking of focusing, such as needs
When specialty to be carried out is taken pictures, described mobile terminal needs situations such as carry out auxiliary shooting using external Laser emission assembly.
Step 102, the luminous power of laser beam obtaining described Laser emission assembly transmitting and the laser beam of described return
The difference of luminous power.
In this step, when described mobile terminal receives the laser beam of return, and the light work(of the laser beam of return is detected
After rate, described mobile terminal, based on the laser beam launched and the laser beam of return, obtains described mobile terminal using described sharp
The luminous power of the laser beam of light emission component transmitting, the difference with the luminous power of the laser beam of the described return receiving.
Wherein, described mobile terminal can be first to obtain to launch, using Laser emission assembly, the luminous power that laser beam is, so
Afterwards in the luminous power of the laser beam based on the return detecting, then reuse respective algorithms and the two is calculated, to obtain
The difference of the two.
Step 103, described difference and predetermined threshold value are compared.
Due to having certain loss in the transmission using laser, especially on the path of transmission, run into barrier etc.
When, therefore, when in focusing window, if unclean, when if any steam or dust, laser beam is from through focusing
Window reaches object of need to focusing and returns again to, receive to described mobile terminal return laser beam when, the overall loss of laser beam
Can be bigger than under normal circumstances, therefore, in this step, when described mobile terminal gets transmitting by calculating or other modes
The luminous power of laser beam with return the difference of the luminous power of laser beam after, described difference is carried out with a predetermined threshold value
Relatively, the loss of the laser beam launched from the point of view of.
If the described difference of step 104 is more than described predetermined threshold value, a prompting message, wherein, described prompting are exported to user
Message is used for reminding user that laser focusing window is cleaned.
In this step, when described mobile terminal passes through to compare to draw, if described difference is more than described predetermined threshold value, then
The laser beam launched is described in transmission way, probably due in focusing window the presence of steam or dust etc. and lead to damage
Loss-rate is larger, and at this moment, described mobile terminal just can export an information to remind user to user, described prompting message
Could be for the information reminding user that laser focusing window is cleaned.
In the embodiment of the present invention, above-mentioned mobile terminal can any use laser be focused, and possesses laser transmitting-receiving group

In this step, when described mobile terminal passes through to compare to draw, if described difference is more than described predetermined threshold value, then
Described mobile terminal can consider the laser beam launched in transmission way, probably due to steam or dust in focusing window
Deng presence and lead to loss ratio larger, but in order to avoid the word error brought of detection, described mobile terminal can control
Time time set in described movement, opens the intervalometer of a Preset Time duration, to carry out buffering and the tune of a period of time
Whole, the time of the intervalometer of the described Preset Time duration setting when described mobile terminal, then described mobile terminal was just permissible
The photographic head controlling described mobile terminal re-starts laser focusing, to be entered detection again, then executes described in described acquisition
The luminous power of laser beam of Laser emission assembly transmitting and the step of the difference of the luminous power of laser beam of described return.
Optionally, the luminous power in the described laser beam obtaining described Laser emission assembly transmitting of described execution is returned with described
After the step of the difference of the luminous power of laser beam returned, methods described includes:
If controlling described mobile terminal to re-start laser focusing, and described difference being still more than described predetermined threshold value,
Then determine that the laser focusing window needs of described mobile terminal are cleaned；Execution is described to export a prompting message to user, wherein,
Described prompting message is used for the step reminding user that laser focusing window is cleaned.
In this step, when the photographic head that described mobile terminal controls described mobile terminal re-starts laser focusing, and
By steps such as detections, when obtaining described difference still more than described predetermined threshold value, then, through inspection more than once
After survey, described mobile terminal is it was determined that totally impact beam transmission may not be there is in the focusing window of described mobile terminal
Thing, as barriers such as steam or dusts that is to say, that described mobile terminal can determine the laser of described mobile terminal
Focusing window needs are cleaned, and described mobile terminal needs user is made prompting, and therefore, described mobile terminal controls to execute
Described to user export a prompting message, wherein, described prompting message is used for reminding user that laser focusing window is cleaned
Step.
Based reminding method provided in an embodiment of the present invention, receives the laser beam returning, wherein, laser beam is to use mobile terminal
Laser emission assembly transmitting；Obtain the luminous power of laser beam of described Laser emission assembly transmitting and the laser beam of described return
Luminous power difference；Described difference and predetermined threshold value are compared；If described difference is more than described predetermined threshold value, to user
Export a prompting message, wherein, described prompting message is used for reminding user that laser focusing window is cleaned；If described difference
Less than or equal to described predetermined threshold value, confirm that the laser focusing window of described mobile terminal does not need to be cleaned；Control institute
The photographic head stating mobile terminal is taken pictures.So, mobile terminal can according to transmitting laser beam luminous power with receive
The luminous power of laser beam difference, judge that focusing window is whether clean, and to can be reminded to user it is ensured that being moved
The degree of accuracy of dynamic terminal focusing, and the cleannes of focusing window are checked without user oneself, time saving and energy saving, be conducive to improving and use
