Specific implementation mode
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the application, rather than the restriction to the application.It also should be noted that in order to just
It is illustrated only in description, attached drawing and the relevant part of the application rather than entire infrastructure.
Fig. 1 is the flow chart of terminal light sensation calibration method embodiment one provided by the embodiments of the present application, as shown in Figure 1, this
Embodiment provide method include：
Step 101, the collected light intensity numerical value of optical sensor is obtained.
Method provided in this embodiment is applied to terminal device, which is the terminal at least one camera
Equipment.Wherein, the camera of terminal device is located at the front or the back side of terminal device, and the peace of the camera in terminal device
Holding position homonymy is additionally provided with optical sensor close to the position of camera.Optical sensor is used to carry out the detection of light intensity numerical value,
The light intensity numerical value detected is sent to the processor of camera or terminal device.Camera is detected according to optical sensor
The completion of light intensity Numerical Control exposure parameter is taken pictures or is imaged；The light intensity number that the processor of terminal device is detected according to optical sensor
The brightness etc. of the backlight illumination, display image screen of value control screen.It is being located at terminal device just with optical sensor and camera
For face, as shown in Fig. 2, Fig. 2, which is optical sensor and camera, is located at the positive schematic diagram of terminal device, wherein camera 21
With optical sensor 22 be respectively positioned on terminal device front, and and above display screen 23, the same side of receiver 24.Camera 21 and light
The distance of sensor 22 is close, from the point of observation other than terminal device, it is believed that camera 21 and optical sensor 22
In same position.
Wherein, optical sensor is integrated light collection, analysis and the integrated chip of processing, by being carried out to light in environment
Acquisition, to analyze the intensity of light.Since the daylighting element that optical sensor is used to carry out light acquisition is located at chip interior,
And optical sensor is installed on terminal inner, therefore the light angle of optical sensor may be restricted.
As shown in figure 3, Fig. 3 is a kind of light angle schematic diagram of optical sensor in terminal.It can be seen from the figure that angle
α is the light angle of optical sensor, and angle beta is the shooting angle (i.e. the light angle of camera) of camera, and angle [alpha] is less than angle
Spend β.And if light source be positioned at A points point light source, then optical sensor will be unable to collect the point light source of A points, if user at this time
Using terminal equipment, then since optical sensor does not collect the point light source of A points, terminal device is by the tune without automatic backlight
Section, shows that the backlight of screen secretly may cause user can not normal use excessively.Again as shown in figure 4, Fig. 4 is optical sensor in terminal
Another light angle schematic diagram.It can be seen from the figure that angle [alpha] is the light angle of optical sensor, angle beta is camera
Shooting angle, angle [alpha] be less than angle beta.And if light source be the point light source positioned at A points and the point light source positioned at B points, then light pass
Sensor will be only capable of collecting the point light source of B points and the point light source that can not collect A points, to the acquisition of light intensity numerical value there may be compared with
Big error needs to be carried out backlight adjusting using light intensity numerical value, brightness of image is adjusted or adjusted exposure parameter of taking pictures in terminal device
When equally possible have an impact.
In the present embodiment, first, or the collected light intensity numerical value of optical sensor is obtained, and in a subsequent step,
By analyzing the image that camera is shot, the collected light intensity numerical value of optical sensor is calibrated.
Step 102, pass through the camera collection image with optical sensor homonymy.
Since terminal device is configured with one or more camera, different cameras and optical sensor detect
Light source may be different, only on the terminal device be located at homonymy optical sensor and the detectable light source of camera be phase
With.Therefore, it when the light intensity numerical value to optical sensor is calibrated, needs by being located at terminal device homonymy with optical sensor
Camera calibrates optical sensor.
From figure 3, it can be seen that the angle of camera shooting is more than the light angle of optical sensor, shot from camera
In luminance information in image, the distribution of light sources situation of different location can be analyzed.It can so be shot using camera
Image the light intensity numerical value that optical sensor acquires is calibrated.It is therefore desirable to pass through the camera with optical sensor homonymy
Image is acquired, due to having not determined accurate light intensity numerical value at this time, camera can use preset light intensity numerical value to carry out
Imaging.
It, can be according to being detected in shooting area in fact, part camera itself also has light sensation detectability
Exposure parameter used in light intensity adjustment imaging, but the light sensation detection of camera itself is simply possible to use in and takes pictures, and nothing
Method is used to show screen to terminal device or shows the brightness regulation of content, also, the light sensation detectability of camera is generally
It is weaker than the light sensation detectability of optical sensor.But in the present embodiment, be using camera shoot image in luminance information
The detection of the light sensation of optical sensor is calibrated, therefore, is taken the photograph as long as the luminance information in image captured by camera reflects
As the Luminance Distribution in head shooting area, you can realize the calibration of the light sensation detection to optical sensor.
Step 103, the full luminance information of the luminance information and image of optical sensor photosensitive region is calculated according to image.
As can be seen that the light angle of optical sensor from the light angle schematic diagram of Fig. 3 or shown in Fig. 4 optical sensors
α is less than the shooting angle β of camera.So, the light angle of optical sensor is mapped in the region of camera shooting, it can be with
Obtain photosensitive region of the optical sensor in the image that camera is shot.As shown in figure 5, Fig. 5, which is camera, shoots showing for image
It is intended to, in Figure 5, region X is the image of camera shooting, and region Y is the photosensitive region of camera, and region Z is optical sensor
Photosensitive region, it is seen then that the photosensitive region of optical sensor be camera shoot image in a part of region, the sense of optical sensor
Light region is less than the photosensitive region of camera.Optical sensor is actually only capable of collecting the light intensity in photosensitive region, and if
Light source is located at the position other than photosensitive region, and light source is point light source, then the collected light intensity of optical sensor will be less than
Collected light intensity is actually answered, obtained light intensity numerical value will be relatively low.
And in the image of camera shooting, each pixel includes the information such as color, brightness, and wherein luminance information also characterizes
The light intensity of each pixel, thus can use the light intensity numerical value that the image that camera is shot acquires optical sensor into
Row calibration.Specifically, in needing to obtain full luminance information and the image of the image of camera acquisition respectively, light sensing
The luminance information of device photosensitive region.
It, can be according in image in the full luminance information of the luminance information and image that obtain optical sensor photosensitive region
The average luminance information of each pixel in the photosensitive region image of optical sensor determines the brightness letter of optical sensor photosensitive region
Breath；According to the average luminance information of each pixel in image, the full luminance information of image is determined.It is of course also possible to use its
His mode obtains above two luminance information, for example obtains the average bright of the pixel after sampling after being sampled to pixel again
Spend information etc..
It should be noted that since optical sensor and camera are all fixedly installed in terminal device, optical sensor
Relative position relation with camera is fixed, then the shooting area of the photosensitive region of optical sensor relative to camera
Relationship is also fixed.Therefore, in the full luminance for the luminance information and image for calculating optical sensor photosensitive region according to image
Before information, the photosensitive region figure of optical sensor in image according to the position relationship of camera and optical sensor, can also be determined
Picture.Namely determine the relative position relation of region X, region Y and region Z in Fig. 5.
Step 104, it is calculated according to the ratio of the full luminance information of the luminance information of optical sensor photosensitive region and image
Light sensation calibration factor.
The luminance information of optical sensor photosensitive region and the full luminance information of image characterize respectively optical sensor by
The light intensity in light intensity and camera shooting area in light region.The relationship of the two luminance informations, also with regard to table
Show the relationship between the optical sensor light intensity numerical value acquired in light area and the light intensity numerical value of camera shooting area.That
Pass through the ratio between the two luminance informations, so that it may to calculate the light sensation calibration system for being calibrated to light intensity numerical value
Number.Usually, the full luminance information of image divided by the luminance information of optical sensor photosensitive region can be obtained light sensation calibration
Coefficient.
Step 105, the light intensity numerical value after calibration is determined according to light intensity numerical value and light sensation calibration factor.
After calculating light sensation calibration factor, you can carried out to the photosensitive coefficient that optical sensor measures using light sensation calibration factor
Calibration, the light intensity numerical value after being calibrated.Specifically, light intensity numerical value is exactly multiplied by light sensation calibration factor, you can calibrated
Light intensity numerical value afterwards.Since the light intensity numerical value after calibration is that the image shot by camera is calibrated, and camera is shot
The image range arrived is wider, avoids in optical sensor sensitive volume there are when point light source, the light intensity number of optical sensor detection
There is large error in value.
After the light intensity numerical value after being calibrated, it is sent to give the camera of optical sensor homonymy, camera
The exposure parameter of camera is adjusted using the light intensity numerical value after calibration, since the light sensation detectability of optical sensor is higher than
The light sensation detectability of camera is imaged using the light intensity numerical value after calibration, the image quality of camera can be made to obtain
To improve.
Or terminal device can also carry out the backlight of terminal device according to it after the light intensity numerical value after being calibrated
Adjust automatically, or the brightness of the image of the display of terminal device is adjusted.In this way, when occurring as shown in Figure 3 or Figure 4
When situation, if can equally obtain correct light intensity numerical value there are when point light source outside optical sensor photosensitive region.Due to terminal
The display screen of equipment is located at terminal device front, therefore, backlight is carried out certainly according to the light intensity numerical value after calibration in terminal device
When the image adjust automatically of dynamic adjustment or display, need according to the light intensity after the corresponding calibration of the positive optical sensor of terminal device
Numerical value is adjusted.
Due to being calibrated to the light intensity numerical value that optical sensor acquires using the image of camera shooting, it is contemplated that camera shooting
The Luminance Distribution of head shooting area, avoids the light angle due to optical sensor limited, causes to be located at optical sensor photosensitive region
Except influence of the point light source to optical sensor accuracy in detection.

Image, then according to the full luminance information of the luminance information of image calculating optical sensor photosensitive region and image and according to light
The ratio of the luminance information in sensor photosensitive region and the full luminance information of image calculates light sensation calibration factor, to according to light
The light intensity numerical value and light sensation calibration factor of sensor acquisition determine the light intensity numerical value after calibration, it is contemplated that camera shooting area
Luminance Distribution avoids the light angle due to optical sensor limited, causes to be located at the point light source except optical sensor photosensitive region
