Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
The technical solution in the embodiment of the present invention is clearly and completely described in middle attached drawing, it is clear that described embodiment is only
It is part of the embodiment of the present invention, instead of all the embodiments.The present invention being usually described and illustrated herein in the accompanying drawings is real
Applying the component of example can be configured to arrange and design with a variety of different.Therefore, below to provide in the accompanying drawings the present invention
The detailed description of embodiment is not intended to limit the range of claimed invention, but is merely representative of the selected reality of the present invention
Apply example.Based on the embodiment of the present invention, institute that those skilled in the art are obtained under the premise of creative work is not made
There is other embodiment, shall fall within the protection scope of the present invention.
In view of in the prior art, when human body biological characteristics identification needs to carry out Image Acquisition, if light condition is not
It is good, it needs to carry out light filling, the mode of light filling of the prior art is using visible light source, which drills user
It says with certain irritation, user experience is poor；It should be mended based on this embodiment of the present invention provides one kind based on screen reality
The method and living creature characteristic recognition system of light.
A kind of method that light filling is carried out based on screen display is provided in one embodiment of the invention, which is equipped with light filling
Area, with reference to shown in FIG. 1, this method comprises the following steps：
S101, light filling control unit carry out illumination condition detection；
S102, in the case that light filling control unit judges that illumination condition is unsatisfactory for preset condition, in image capture module
Triggering generation control instruction during Image Acquisition is carried out, is sent and is triggered and the control instruction is sent to the screen；
Only be provided with light filling area in advance on screen or be provided with light filling area and other display areas simultaneously, this other it is aobvious
Show that region includes：Visual feedback area and information display area, visual feedback area are used to show that the image collecting devices such as camera are adopted
The image of collection, video information；Information display area can be for showing the information such as the words such as weather forecast, image, video；It is above-mentioned
The quantity in the light filling area on screen can be one or more.
The purpose of the detection of above-mentioned carry out illumination condition is to obtain current illumination condition；Can be illustratively aobvious at this
Show and photosensitive sensor is set in module, illumination condition detection is carried out by the photosensitive sensor.
S103, the screen carry out light filling in response to the control instruction according to preset light filling mechanism.
When the illumination condition of detection, which cannot meet, carries out the required illumination condition of picture collection, in image capture module
When carrying out Image Acquisition, which can be camera, can trigger generation control instruction, and the control instruction is sent out
It send to screen, screen can carry out light filling in response to the control instruction after receiving the control instruction according to preset light filling mechanism；
Specifically, screen can carry out light filling in the following way：
Mode one, the display brightness for adjusting screen light filling area；
The display brightness in screen automatic adjustment light filling area, is irradiated with different light intensity, to achieve the purpose that light filling.
Mode two shows the image content with specific color in screen light filling area；
The materials such as display picture, animation or video with specific color, are adjusted so as to realize indirectly in screen light filling area
The luminance information in light filling area.
Mode three shows dynamic image in a fixed order in screen light filling area, so as to dynamic regulation screen light filling area
Display brightness；
Screen protection picture, curve or customization performance graph are shown in the light filling area of screen, so as to fulfill dynamic modulation
The luminance information in light filling area.
Mode four, the brightness for adjusting preset virtual light source in the screen light filling area；
Multiple virtual light sources (such as can be the bright spot of the setting on screen) are set in the light filling area of screen, and further
By preset condition modulation virtual light source luminance information.
When on above-mentioned screen while light filling is carried out, it is also necessary to carry out display image capture module acquired image or
Can be in a manner that timesharing is shown, when needing to carry out light filling, screen is carried out according to pre- when person carries out display other information
If light filling mechanism carry out light filling, perform image display and carry out the display of other information at other time points, it is whole at this time
The display area of a screen is either light filling area can also be visual feedback area, information display area or can also be simultaneously
There is multiple viewing area, only to avoid interfering light filling, light filling area with other regions can put and work in different times.
For another example work as in addition to light filling area on screen, it is above-mentioned when also including visual feedback area and/or other information viewing area simultaneously
Layout type between light filling area and visual feedback area and/or other information viewing area can use following several ways：Side
Formula one is configured according to preset area accounting；Mode two, when light filling area, visual feedback region and other information viewing area
During with lap, multiple region subdivision is shown, illustratively, light filling area is located at lowest level, visual feedback
Area is in top layer；Mode three carries out visual feedback area special efficacy rendering design；Such as according to recognition of face feedback data, only will
Facial image part is rendered on Background From Layer；Visual feedback area rendering effect is unlimited herein, such as renders visual feedback area saturating
Circular pattern is for another example rendered to by the pattern of lightness gradual change by visual feedback area.
Caused burn-in phenomenon when screen is used as light filling in order to prevent can take control screen light filling into Mobile state tune
System or screen display dynamic pattern scheme.
It should be noted that above are only for example, can be there are many realization method in specific implementation, it therefore should not
Regard limitation of the present invention as.
A kind of living creature characteristic recognition system is provided in another embodiment of the present invention, with reference to embodiment shown in Fig. 2,
The system includes：
