Description

Light filling mould group and terminal device
Technical field
The present invention relates to a kind of light filling mould group and terminal devices.
Background technique
With the development of terminal device, terminal device is also constantly updating iteration while integrating more and more functions. In order to obtain preferable shooting effect, more and more terminal devices are in same shooting direction configured at least two camera shootings at present Head.For example, terminal equipment configuration more at present has postposition dual camera.
In order to promote shooting performance, terminal device includes at least two unequal cameras of field angle, the view of camera Its unequal focal length of rink corner is then unequal.The focal length of camera is bigger, and correspondingly the field angle of the camera is then smaller;Camera Focal length it is smaller, correspondingly the field angle of the camera is then bigger.At least two field angle of terminal equipment configuration is unequal to be taken the photograph As head, it can achieve the purpose that zoom shot indirectly by the work of switching camera, to be able to satisfy the different shooting of user Demand.
Terminal device is usually also configured with light filling mould group, and light filling mould group can carry out light filling for the shooting of camera, in turn Enable to terminal device shooting can be completed in dark situation (such as night, cloudy day, light gloomy basement etc.).But The light filling angle initialization of the light filling mould group of current terminal device, can not match at least two camera shootings of different field angles simultaneously Head, and then it is unable to reach the purpose of matching light filling, such as when the light filling angle of light filling mould group is matched with the biggish camera of field angle, It if the switching lesser camera of field angle is shot, will appear light filling mould group since light filling region is larger, and lead to illumination The utilization rate of intensity is lower.When the light filling angle of light filling mould group is matched with the lesser camera of field of view angle, if switching field angle When biggish camera is shot, then it will appear part shooting area and be unable to get light filling, and influence light filling effect.
Summary of the invention
The present invention discloses a kind of light filling mould group, can not match different visual fields to solve the light filling mould group of current terminal device The problem of camera at angle is shot.
To solve the above-mentioned problems, the present invention adopts the following technical solutions:
A kind of light filling mould group, it is described including light compensating lamp, SMA motor and the light distribution eyeglass being oppositely arranged with the light compensating lamp SMA motor be connected with the light distribution eyeglass and drive the light distribution eyeglass away from or close to the light compensating lamp direction move It is dynamic.
A kind of terminal device, including shell and light filling mould group described above, the light filling mould group is arranged in the shell It is interior.
The technical solution adopted by the present invention can reach it is following the utility model has the advantages that
In light filling mould group disclosed in the present embodiment, light distribution eyeglass is oppositely arranged with light compensating lamp, and then is matched for light compensating lamp Light.Light distribution eyeglass is connected with SMA motor, and then can move under the driving effect of SMA motor to adjust between light compensating lamp Distance.The variation of the distance between light distribution eyeglass and light compensating lamp enables to the light filling angle in light filling region to change, so that mending Optical mode group can be adapted to the shooting of the camera of different field angles.As it can be seen that light filling mould group disclosed by the embodiments of the present invention can solve The problem of camera that current light filling mould group can not match different field angles is shot.
