Embodiment one

Fig. 1 is the flow chart of the photographic method of one embodiment of the invention.Photographic method shown in Fig. 1 includes:

Step 101, open the front-facing camera of described mobile terminal.

The purpose of the embodiment of the present invention is: when front-facing camera works, use light filling element to front-facing camera light filling, Improve the brightness of front-facing camera local environment, thus obtain image data clearly.

In the embodiment of the present invention, mobile terminal can be mobile phone, flat board, notebook etc..

Mobile terminal is provided with front-facing camera, is mounted with preposition flash lamp near front-facing camera.Preposition flash lamp Front-facing camera can be carried out light filling, improve the brightness of front-facing camera surrounding.Front-facing camera has flash of light and mends Light two effect.User puts photographic head before use and carries out taking pictures or during video calling, due to subject and distance of mobile terminal Relatively near, therefore for protection user's eye, generally control preposition flash lamp and only carry out light filling operation, do not carry out flash operation.Additionally The display screen that can also use mobile terminal carries out light filling to front-facing camera.

User uses front-facing camera to carry out taking pictures or during other operations in advance, it is necessary first to starts front-facing camera, starts The mode of front-facing camera can include multiple, such as, select the functional entrance of front-facing camera, pressing to move from menu option Button in dynamic terminal starts front-facing camera, input voice information starts front-facing camera etc..Correspondingly, system is receiving After the instruction starting front-facing camera that user triggers, open the front-facing camera of mobile terminal.

Step 102, the distance detected between described mobile terminal and the object of shooting.

Owing to mobile terminal is provided with preposition flash lamp, therefore mobile terminal includes two kinds of light filling elements, the most preposition glazing Lamp and the display screen of mobile terminal.Preposition flash lamp is different with the light filling effect of display screen, relative to preposition flash lamp, mobile whole The light filling effect of the display screen of end is more weak.

After front-facing camera is opened, for satisfied shooting brightness demand, need front-facing camera is carried out light filling, due to movement The light filling element of terminal exists two kinds, it is therefore desirable to select light filling element.

The shooting effect of front-facing camera can be impacted by the distance between mobile terminal and the object of shooting. When the object of mobile terminal Yu shooting is distant, the definition of filmed image is poor, for obtaining filmed image clearly, Need to provide bigger light filling brightness for front-facing camera, preposition flash lamp therefore can be selected as light filling element;Work as movement When terminal is close together with the object of shooting, being only required to be front-facing camera provides less light filling brightness can meet shooting need Ask, the display screen of mobile terminal therefore can be selected as light filling element.By above-mentioned analysis, can be according to mobile terminal And the distance between object, selects the light filling element being more suitable for, and then provides suitable light filling brightness for front-facing camera.

After putting photographic head before opening, it is possible to use the range sensor detection detection being installed in mobile terminal is mobile eventually Distance between end and object.Wherein, the content of object can determine according to shooting demand, such as, use preposition as user When photographic head is autodyned, object is personage;When user uses front-facing camera photographed, object is scenery.

Step 103, according to described distance select light filling element, wherein, described light filling element includes display screen and preposition sudden strain of a muscle Light modulation.

The light filling element of mobile terminal includes display screen and preposition flash lamp.Can be according to the mobile terminal detected and mesh Distance between mark thing, determines required light filling brightness, and then determines the kind of light filling element.Generally mobile terminal and object Between distance the biggest, required light filling brightness is the biggest, and preposition flash lamp at this moment can be selected as light filling element;Otherwise, institute The light filling brightness needed is the least, selects display screen as light filling element.

In concrete operations, can arrange distance threshold, the distance between the mobile terminal detected and object is more than During distance threshold, determine that preposition flash lamp is as light filling element;Distance between mobile terminal and object is less than distance threshold During value, determine that display screen is as light filling element.
