Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
It is a kind of structural schematic diagram of camera shooting light compensating apparatus provided in an embodiment of the present invention referring to Fig. 1, Fig. 1, images light filling
Device is installed in the mobile terminal including front camera and rear camera, as shown in Figure 1, camera shooting light compensating apparatus includes：
Light filling module 10, light filling module 10 include flash lamp 11, rotating mirror 12, front glass 13 and postposition glass
14, front glass 13 is located at the side where front camera, and postposition glass 14 is located at the side where rear camera；
Controller (not shown), controller are used for when front camera images, and control rotating mirror 12 is rotated to preceding
Reflective condition is set, the light that flash lamp 11 is sent out is made to reflect and penetrates the injection of front glass 13；When rear camera images, control
Rotating mirror 12 processed rotation makes the light that flash lamp 11 is sent out reflect and penetrates postposition glass 14 to penetrate to postposition reflective condition
Go out.
Wherein, rotating mirror 12 can be by minute surface, positioned at the mirror axis and shaft and mirror axis of minute surface Pivot axle
The motor form of connection, controller are electrically connected with motor, and control motor rotation to drive minute surface to rotate, makes flash lamp 11 send out
Light reflection, and projected through front glass 13 or postposition glass 14, to realize to front camera or rear camera
Light filling when camera shooting.It is, of course, also possible to which the rotation button for the rotation angle for adjusting rotating mirror 12 manually for user is arranged.
It should be noted that above-mentioned light filling module 10 can be installed on the area close to front camera or rear camera
Domain, it is of course also possible to need to be installed on other regions other than screen according to user.In addition, above-mentioned front glass 13 is installed on
The side of the screen of mobile terminal, i.e. side where front camera, postposition glass 14 are installed on the separate screen of mobile terminal
The side of curtain, i.e. side where rear camera.
Optionally, controller is additionally operable to when front camera images, and the input current value of control flash lamp 11 is first
Current value makes light filling module be operated in sheen pattern；When rear camera images, the input current value for controlling flash lamp is the
Two current values make light filling module be operated in flash mode.
When wherein, due to the current value difference of the input of flash lamp 11, the light intensity sent out is also different, and current value is small,
Light intensity is weak；Current value is big, and light intensity is strong.Meanwhile during actually imaging, front camera usually requires when imaging
The weaker sheen pattern of light intensity carries out light filling, and when rear camera images need the stronger flash mode of light intensity into
Row light filling.

Whether step 301, detection front camera and rear camera are in camera shooting state.
Step 302, when detect front camera camera shooting when, controller control rotating mirror rotate to preposition reflection shape
State makes the light that flash lamp is sent out reflect and penetrates front glass injection.
Step 303, when detect rear camera camera shooting when, controller control rotating mirror rotate to postposition reflect shape
State makes the light that flash lamp is sent out reflect and penetrates the injection of postposition glass.
Whether exposure value when step 304, detection currently camera shooting matches with the rotation angle of rotating mirror.
In the embodiment of the present invention, during front camera or rear camera image, mobile terminal, which can detect, works as
It is proactive as when exposure value, such as：Imaging environment can be obtained by the photosensitive module of front camera or rear camera
Light intensity, mobile terminal can determine exposure value when current camera shooting according to light intensity.
Wherein, mobile terminal can pre-set the rotation angle of the exposure value rotating mirror 12 when at least two groups image
Mapping relations mapping table, exposure value when above-mentioned detection currently images whether the rotation angle with rotating mirror 12
Matching, it can be understood as：Mobile terminal detects whether current exposure value and rotation angle deposit in the mapping table of storage
In mapping relations, if mapping relations are not present with rotation angle in current exposure value, it is determined that exposure value when current camera shooting with
The rotation angle of rotating mirror 12 mismatches.
Can also be reflecting for levels of exposure and rotation angle it should be noted that above-mentioned pre-set mapping table
Relationship is penetrated, herein without limiting.In addition, not due to the light intensity that is needed when front camera and rear camera image
Together, the relationship map of exposure value and rotation angle when front camera and rear camera camera shooting can be respectively set as needed
Table.
If step 305, exposure value and rotation angle mismatch, controller adjusts the rotation angle of rotating mirror to exposing
It is worth matched target rotation angle.
In the embodiment of the present invention, if the rotation angle of the exposure value and rotating mirror 12 when current camera shooting mismatches, control
Current rotation angle can be adjusted to the matched target rotation angle of current exposure value by device processed, to which mobile terminal can be with
Exposure value when according to camera shooting adjusts the rotation angle of rotating mirror 12, improves pickup quality.
Such as：When preset front camera images in the mapping table of exposure value and rotation angle, exposure value 1s
With there are mapping relations between 30 ° of rotation angle, if exposure value when current camera shooting is 1s, and the rotation angle of rotating mirror 12
Degree is when rotating clockwise 25 °, the rotation angle that controller can control rotating mirror 12 switches to and rotates clockwise 30 °.
