Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a first embodiment of a terminal light sensation calibration method according to an embodiment of the present application, and as shown in fig. 1, the method according to the embodiment includes:
The method provided by the embodiment is applied to the terminal equipment which is provided with at least one camera. The camera of the terminal equipment is positioned on the front side or the back side of the terminal equipment, and the optical sensor is arranged at the same side of the mounting position of the camera of the terminal equipment and close to the position of the camera. The optical sensor is used for detecting the light intensity value and sending the detected light intensity value to the camera or a processor of the terminal equipment. The camera controls exposure parameters according to the light intensity numerical value detected by the light sensor to finish photographing or shooting; and the processor of the terminal equipment controls the backlight brightness of the screen, the brightness of a displayed image of the screen and the like according to the light intensity value detected by the light sensor. Taking the example that the optical sensor and the camera are located on the front side of the terminal device, as shown in fig. 2, fig. 2 is a schematic diagram that the optical sensor and the camera are located on the front side of the terminal device, wherein the camera 21 and the optical sensor 22 are both located on the front side of the terminal device, and above the display screen 23, the same side of the earpiece 24 is located. The camera 21 and the optical sensor 22 are located at a close distance, and the camera 21 and the optical sensor 22 can be considered to be located at the same position when viewed from a viewpoint other than the terminal device.
Wherein, light sensor gathers for integrated light, the chip that integrates of analysis and processing through gathering light in to the environment to the intensity of analysis play light. Because the lighting element used for collecting light of the optical sensor is positioned in the chip and the optical sensor is installed in the terminal, the light receiving angle of the optical sensor may be limited.
As shown in fig. 3, fig. 3 is a schematic diagram of a light receiving angle of a light sensor in a terminal, it can be seen from the diagram that an angle α is the light receiving angle of the light sensor, an angle β is the shooting angle of a camera (i.e. the light receiving angle of the camera), and an angle α is smaller than an angle β. if the light source is a point light source located at point a, the light sensor cannot collect the point light source at point a, if the user uses the terminal device at this time, the backlight of a display screen may be too dark to be normally used by the user because the light sensor does not collect the point light source at point a, and as shown in fig. 4, another light receiving angle of the light sensor in the terminal is a schematic diagram, angle α is the light receiving angle of the light sensor, angle β is the shooting angle of the camera, angle α is smaller than angle β.
In this embodiment, first, the light intensity value collected by the light sensor is also obtained, and in the subsequent step, the light intensity value collected by the light sensor is calibrated by analyzing the image taken by the camera.
And 102, acquiring an image through a camera on the same side of the optical sensor.
Since the terminal device may be equipped with one or more cameras, the light sources detected by different cameras and light sensors may be different, only the light sources detectable by the light sensors and cameras on the same side of the terminal device being identical. Therefore, when the light intensity value of the light sensor is calibrated, the light sensor needs to be calibrated by a camera which is positioned on the same side of the terminal equipment as the light sensor.
As can be seen from fig. 3, the shooting angle of the camera is greater than the light receiving angle of the optical sensor, and the light source distribution conditions at different positions can be analyzed from the brightness information in the image shot by the camera. The light intensity value collected by the light sensor can be calibrated by using the image shot by the camera. Therefore, images need to be acquired through the camera on the same side of the optical sensor, and since the accurate light intensity value is not determined at this time, the camera can use the preset light intensity value for imaging.
In fact, some cameras themselves also have light sensing detection capability, and exposure parameters used for imaging can be adjusted according to the light intensity detected in the shooting area, but the light sensing detection of the cameras itself can only be used for shooting, but cannot be used for brightness adjustment of a display screen or display content of the terminal device, and the light sensing detection capability of the cameras is generally weaker than that of the light sensor. However, in the present embodiment, the light-sensitive detection of the light sensor is calibrated by using the brightness information in the image captured by the camera, and therefore, the calibration of the light-sensitive detection of the light sensor can be realized as long as the brightness information in the image captured by the camera reflects the brightness distribution in the imaging area of the camera.
And 103, calculating brightness information of a photosensitive area of the photosensor and complete brightness information of the image according to the image.
As can be seen from the light receiving angle diagrams of the optical sensor shown in fig. 3 or fig. 4, the light receiving angle α of the optical sensor is smaller than the shooting angle β of the camera, then the light receiving angle of the optical sensor is mapped in the area shot by the camera, and the light sensing area of the optical sensor in the image shot by the camera can be obtained, as shown in fig. 5, fig. 5 is a diagram of the image shot by the camera, in fig. 5, the area X is the image shot by the camera, the area Y is the light sensing area of the camera, the area Z is the light sensing area of the optical sensor, it can be seen that the light sensing area of the optical sensor is a partial area in the image shot by the camera, and the light sensing area of the optical sensor is smaller than the light sensing area of the camera.
And in the image that the camera was shot, every pixel includes information such as colour, luminance, and wherein luminance information has also represented the light intensity of every pixel, consequently can use the image that the camera was shot to calibrate the light intensity numerical value that the optical sensor gathered. Specifically, it is necessary to obtain complete brightness information of an image collected by the camera and brightness information of a photosensitive area of the optical sensor in the image.
When the brightness information of the photosensitive area of the optical sensor and the complete brightness information of the image are obtained, the brightness information of the photosensitive area of the optical sensor can be determined according to the average brightness information of each pixel point in the image of the photosensitive area of the optical sensor in the image; and determining the complete brightness information of the image according to the average brightness information of each pixel point in the image. Of course, the two kinds of luminance information may also be obtained in other manners, such as sampling the pixel point and then obtaining the average luminance information of the sampled pixel point.
It should be noted that, since the optical sensor and the camera are both fixedly installed in the terminal device, and the relative positional relationship between the optical sensor and the camera is fixed, the relationship between the light sensing area of the optical sensor and the shooting area of the camera is also fixed. Therefore, before the brightness information of the light sensing area of the light sensor and the complete brightness information of the image are calculated according to the image, the light sensing area image of the light sensor in the image can be determined according to the position relation of the camera and the light sensor. That is, the relative positional relationship of the area X, the area Y, and the area Z in fig. 5 is determined.
And 104, calculating a light sensation calibration coefficient according to the ratio of the brightness information of the light sensing area of the light sensor to the complete brightness information of the image.
The brightness information of the photosensitive area of the optical sensor and the complete brightness information of the image respectively represent the light intensity in the light receiving area of the optical sensor and the light intensity in the shooting area of the camera. The relationship between the two pieces of brightness information also represents the relationship between the light intensity value acquired by the light sensor in the light receiving area and the light intensity value in the shooting area of the camera. Then the light-sensitive calibration factor for calibrating the light intensity value can be calculated from the ratio between the two luminance information. Generally, the entire brightness information of the image can be divided by the brightness information of the photosensitive area of the photosensor to obtain the photosensitive calibration coefficient.
And 105, determining the calibrated light intensity value according to the light intensity value and the light sensation calibration coefficient.
After the light sensation calibration coefficient is calculated, the light sensation calibration coefficient can be used for calibrating the light sensation coefficient measured by the light sensor, and a calibrated light intensity numerical value is obtained. Specifically, the light intensity value is multiplied by the light sensation calibration coefficient to obtain the calibrated light intensity value. The calibrated light intensity value is calibrated by the image shot by the camera, and the range of the image shot by the camera is wider, so that the problem that the light intensity value detected by the optical sensor has larger error when a point light source is stored in the photosensitive range of the optical sensor is solved.
After the calibrated light intensity value is obtained, the calibrated light intensity value is sent to the camera on the same side of the optical sensor, the camera can adjust exposure parameters of the camera by using the calibrated light intensity value, and the calibrated light intensity value is used for imaging because the light sensing detection capability of the optical sensor is higher than that of the camera, so that the imaging quality of the camera can be improved.
Or after the terminal device obtains the calibrated light intensity value, the backlight of the terminal device can be automatically adjusted according to the light intensity value, or the brightness of the image displayed by the terminal device can be adjusted. Thus, when the situation shown in fig. 3 or fig. 4 occurs, if a point light source exists outside the light-sensing area of the photosensor, the correct light intensity value can be obtained. Because the display screen of the terminal device is located on the front side of the terminal device, when the terminal device performs backlight automatic adjustment or displayed image automatic adjustment according to the calibrated light intensity value, the terminal device needs to adjust according to the calibrated light intensity value corresponding to the optical sensor on the front side of the terminal device.
Because the light intensity numerical value of the image shot by the camera and collected by the optical sensor is calibrated, the brightness distribution of the shooting area of the camera is considered, and the influence of a point light source outside the photosensitive area of the optical sensor on the detection accuracy of the optical sensor due to the limited light receiving angle of the optical sensor is avoided.
According to the terminal light sensation calibration method provided by the embodiment of the application, the camera on the same side as the optical sensor is used for collecting the image, then the brightness information of the light sensitive area of the optical sensor and the complete brightness information of the image are calculated according to the image, and the light sensation calibration coefficient is calculated according to the proportion of the brightness information of the light sensitive area of the optical sensor and the complete brightness information of the image, so that the calibrated light intensity value is determined according to the light intensity value collected by the optical sensor and the light sensation calibration coefficient, the brightness distribution of the shooting area of the camera is considered, the influence of a point light source outside the light sensitive area of the optical sensor on the detection accuracy of the optical sensor due to the limited light receiving angle of the optical sensor is avoided, and the detection accuracy of the optical sensor.
