Description

Ambient light intensity calibration method and device and electronic equipment

Technical Field

The present application relates to the field of ambient light detection technologies, and in particular, to an ambient light intensity calibration method, an ambient light intensity calibration device, an electronic device, and a computer-readable storage medium.

Background

Currently, when the terminal automatically adjusts the screen brightness, the terminal generally adjusts the screen brightness according to a linear relationship between the ambient brightness and the screen brightness, wherein the ambient brightness is detected by a light sensor disposed in the terminal. In the related art, the light sensor is usually disposed at the top of the terminal display screen, i.e., below the transparent glass in the shape of a small circular hole near the receiver of the terminal, and light passes through the transparent glass and can directly reach the light sensor, so that the light sensor can directly sense the change of the ambient light brightness. The electronic equipment can control the brightness of the display screen according to the detected brightness of the external environment light, so that the brightness of the display screen is adaptive to the external environment.

However, for a terminal with a full-screen display screen, since there is no position on the top of the display screen where a Light sensor can be placed, and the ambient Light sensor is hidden under an Organic Light Emitting Diode (OLED) display screen, since the self-luminescence of the OLED pixels may interfere with the detection of the ambient Light device, and affect the detection accuracy of the ambient Light device, the intensity of the ambient Light detected by the ambient Light sensor needs to be calibrated.

For example, in the prior art, the screen interference calibration processing is performed on the ambient light collected by a single ambient light sensor to obtain the real ambient light, however, when the display screen is deformed or the electronic device is bent to a certain state for use, the screen interference area changes, and thus the accuracy of the ambient light detected by the electronic device after bending is low.

Referring to fig. 2 and fig. 3, fig. 2 is a front view of an electronic device 100 according to an embodiment of the present disclosure; fig. 3 is a cross-sectional view of an electronic device 100 according to an embodiment of the present application. As shown in fig. 2 and 3, in the embodiment of the present application, the electronic device 100 includes two ambient light sensors 180L. Of course, the electronic device 100 may further include more ambient light sensors 180L, which is not limited herein. For convenience of description, the two ambient light sensors 180L will be hereinafter referred to as a first ambient light sensor 180L1 and a second ambient light sensor 180L2, respectively. The first and second ambient light sensors 180L1 and 180L2 are both disposed below the display screen 194. It is understood that the display screen 194 includes opposing display and non-display surfaces. The lower side of the display screen 194 refers to a non-display surface of the display screen 194.

In the embodiment of the present application, the electronic device 100 further includes a circuit board 101, and the first ambient light sensor 180L1 and the second ambient light sensor 180L2 are both disposed on the circuit board 101. The circuit board 101, also called a motherboard in the electronic device 100, is one of the most basic and important components of the electronic device 100, and various control chips (such as the processor 110 and the I/O control chip) and various electronic components (such as various chips, resistors, capacitors, etc.) are mounted on the circuit board 101 and have wires distributed thereon. The first ambient light sensor 180L1 and the second ambient light sensor 180L2 may be electrically connected to the processor 110 disposed on the circuit board 101 through specific wires.

For example, in practical operation, the first ambient light sensor 180L1 and the second ambient light sensor 180L2 may be placed under the display screen 194, and a protective film is cut under the display screen 194 to ensure that the display screen 194 has good light transmittance. In addition, the first ambient light sensor 180L1 and the second ambient light sensor 180L2 are disposed on the circuit board 101 with a distance from the display screen 194 controlled within a predetermined distance (e.g., 0.8mm) in consideration of force and wiring, so that the viewing angle of the ambient light sensors can be controlled while preventing external force from being squeezed.

Referring to fig. 2 again, the display screen 194 has a bending region 102. The electronic device 100 can be bent along the bending region 102. That is, when the user does not use the electronic apparatus 100, it may be folded to a closed state for convenient carrying; when the user needs to use the electronic device 100, the electronic device can be unfolded to an open state to increase the use area of the display screen.

In this embodiment, the display screen 194 is an OLED flexible display screen, and since the self-luminescence of the OLED pixels may affect the detection accuracy of the ambient light, the intensity of the ambient light detected by the ambient light sensor 180L needs to be calibrated. However, the calibration method in the prior art is based on the display screen 194 being in an unbent state, and is not suitable when the display screen 194 is deformed or the electronic device 100 is bent to a certain state (as shown in fig. 4), which results in a low accuracy of the ambient light detected by the electronic device 100 after bending. Therefore, it is desirable to provide an ambient light intensity calibration method according to an embodiment of the present invention, which can perform different calibration processes according to whether the electronic device 100 is bent, and further can improve the detection accuracy of the ambient light of the electronic device 100 in the bent state.

Referring to fig. 5, fig. 5 is a flowchart illustrating an ambient light intensity calibration method according to an embodiment of the present disclosure. The ambient light intensity calibration method is applied to the electronic device 100. Specifically, the ambient light intensity calibration method includes the following steps:

step S11, obtaining a first detected ambient light intensity output by the first ambient light sensor and a second detected ambient light intensity output by the second ambient light sensor when the electronic device is in a bent state.

The bending state in the embodiment of the present application may be recognized by an angle sensor (not shown) provided at the bending region 102. In other embodiments, whether the electronic device 100 is bent or not may also be detected by the plurality of pressure sensors 180A disposed at the bending region 102. For example, when the electronic device 100 is bent, the pressure sensor 180A disposed at the bending region 102 detects different pressure values due to the pressure.

Step S12, calibrating the first detection ambient light intensity and the second detection ambient light intensity according to the bent predicted screen interference area, and determining the real ambient light intensity according to the processing result.

It is understood that, when the electronic device 100 is bent, although the interference area of the display screen 194 changes with respect to the first ambient light sensor 180L1 and the second ambient light sensor 180L2, since the first ambient light sensor 180L1 and the second ambient light sensor 180L2 are located in the same environment, the true intensity of the ambient light detected by the first ambient light sensor 180L1 and the second ambient light sensor 180L2 should be substantially the same.

The interference areas refer to areas corresponding to the first ambient light sensor 180L1 and the second ambient light sensor 180L2, respectively. By substantially the same, it is meant that the true intensities of the ambient light detected by the first ambient light sensor 180L1 and the second ambient light sensor 180L2 are the same, or that the error of the true intensities of the ambient light detected by the first ambient light sensor 180L1 and the second ambient light sensor 180L2 is within a preset threshold range.

In other embodiments, the electronic device 100 may further include a greater number of ambient light sensors 180L, and when the electronic device 100 includes a greater number of ambient light sensors 180L, the ambient light detected by the greater number of ambient light sensors may be calibrated to obtain the actual ambient light intensity.

In the embodiment of the present application, by obtaining the first detection environment light intensity output by the first environment light sensor 180L1 and the second detection environment light intensity output by the second environment light sensor 180L2 of the electronic device in the bent state, the first detection environment light intensity and the second detection environment light intensity are respectively calibrated to determine the real environment light intensity according to the predicted screen interference area after bending, so that the detection accuracy of the environment light after bending of the electronic device 100 can be improved.

Specifically, referring to fig. 6, fig. 6 is a flowchart illustrating a detailed process of step S12 in fig. 5. In one embodiment, step S12 includes the following steps:

in step S121, a first prediction screen interference area and a second prediction screen interference area are determined. The first prediction screen interference area is an area which is possibly corresponding to the first ambient light sensor after the electronic equipment is bent; the second prediction screen interference area is an area which the second ambient light sensor may correspond to after the electronic device is bent.

It is understood that, when the electronic device 100 is bent, the relative position between the display 194 and the first ambient light sensor 180L1 changes, and the relative position between the display 194 and the second ambient light sensor 180L2 also changes. That is, the screen interference areas of the display screen 194 are changed relative to the screen interference areas of the first ambient light sensor 180L1 and the second ambient light sensor 180L2, however, the screen interference areas of the display screen 194 have uncertainty each time the electronic device 100 is bent due to different deformation degrees of the display screen 194 and single difference of the display screen 194, and therefore, it is necessary to determine the predicted screen interference areas first, and then determine according to the subsequent steps, whether the predicted screen interference areas determined currently are actual screen interference areas.

In some embodiments, in order to improve the accuracy and speed of determining the first predicted screen interference region and the second predicted screen interference region, the first predicted screen interference region and the second predicted screen interference region are sequentially determined in a successive approximation manner with the first preset region and the second preset region as starting points, respectively. The first preset area is an area corresponding to the first ambient light sensor when the electronic device is not bent, and the second preset area is an area corresponding to the second ambient light sensor when the electronic device is not bent.

Wherein, the successive approximation mode is as follows: determining the first prediction screen interference area by taking a first preset step length as a unit in sequence from the starting point of the first preset area to a first preset direction; and determining the second prediction screen interference area by taking the second preset area as a starting point and sequentially taking a second preset step length as a unit towards a second preset direction. I.e. the pixels are traversed in a predetermined area with a certain step size. The first preset step length and the second preset step length may be the same or different, and may be specifically set according to an actual situation, which is not limited herein in the embodiments of the present application.

In some embodiments, the first preset direction is determined by the relative positions of the bending region 102 of the electronic device 100 and the first ambient light sensor 180L 1; the second predetermined direction is determined by the relative positions of the bending region 102 of the electronic device 100 and the second ambient light sensor 180L 2. For example, when the first ambient light sensor 180L1 and the second ambient light sensor 180L2 are located on the same side of the bending region 102, when the electronic device 100 is bent, the first ambient light sensor 180L1 and the second ambient light sensor 180L2 have the same dislocation direction relative to the display screen 194, and thus, the first preset direction and the second preset direction are the same. For another example, when the first ambient light sensor 180L1 and the second ambient light sensor 180L2 are respectively located at two sides of the bending region 102, when the electronic device 100 is bent, the first ambient light sensor 180L1 and the second ambient light sensor 180L2 have different dislocation directions relative to the display screen 194, and therefore, the first preset direction and the second preset direction are also different.

It is understood that the first ambient light sensor 180L1 and the second ambient light sensor 180L2 may be separate devices or may be packaged as a single device, and the specific implementation manner is not limited herein.

Step S122, determining a first screen interference value corresponding to the first prediction screen interference region according to the display content of the first prediction screen interference region, and determining a second screen interference value corresponding to the second prediction screen interference region according to the display content of the second prediction screen interference region.

The different display contents cause the luminous intensity and color of the display screen 194 to be different, and further cause the interference of the different display contents on the ambient light sensor 180L to be different and the same. Specifically, the screen interference value corresponding to the current display content may be determined according to a relationship between the display content preset in the internal memory 121 and the screen interference value. The relationship between the display content and the screen interference value may be a comparison table or a formula, which may be obtained through a large amount of experimental test data, and is not specifically limited herein.

Step S123, calculating a difference between the first detected ambient light intensity and the first screen interference value to obtain a first calibrated ambient light intensity, and calculating a difference between the second detected ambient light intensity and the second screen interference value to obtain a second calibrated ambient light intensity.

In this embodiment, the calibrated ambient light intensity can be obtained by filtering the detected ambient light intensity from the screen interference value of the display screen 194.

Step S124, determining whether a difference between the first calibrated ambient light intensity and the second calibrated ambient light intensity is smaller than a preset threshold; if yes, go to step S125; if not, step S121 is executed.

If the difference between the first calibrated ambient light intensity and the second calibrated ambient light intensity is not less than the preset threshold, it indicates that the currently determined first predicted screen interference region and the second predicted screen interference region are not actual interference regions, so step S121 and subsequent steps need to be re-executed until whether the difference between the first calibrated ambient light intensity and the second calibrated ambient light intensity is less than the preset threshold. Thus, the detection accuracy of the ambient light can be improved.

Step S125, when a difference between the first calibrated ambient light intensity and the second calibrated ambient light intensity is smaller than a preset threshold, taking the first calibrated ambient light intensity, the second calibrated ambient light intensity, or an average value of the first calibrated ambient light intensity and the second calibrated ambient light intensity as a real ambient light intensity.

When the difference between the first calibrated ambient light intensity and the second calibrated ambient light intensity is smaller than the preset threshold, it indicates that the intensities of the ambient light detected by the first ambient light sensor 180L1 and the second ambient light sensor 180L2 are substantially the same, and at this time, the first predicted screen interference area and the second predicted screen interference area may be determined to be actual screen interference areas.

Fig. 7 is a flowchart illustrating an ambient light intensity calibration method according to another embodiment of the present application. In one embodiment, the ambient light intensity calibration method further comprises the following steps.

Step S13, obtaining a first detected ambient light intensity output by the first ambient light sensor or a second detected ambient light intensity output by the second ambient light sensor when the electronic device is not bent.

When the electronic device 100 is not bent, the real ambient light intensity can be obtained by only acquiring the detected ambient light intensity output by one ambient light sensor 180L, so that the efficiency of the ambient light intensity calibration method when the electronic device 100 is not bent can be improved.

Step S14, calibrating the first detection environment light intensity or the second detection environment light intensity according to the screen interference area when the screen is not bent, and determining the real environment light intensity according to the processing result; the screen interference area when the electronic device is not bent is an area corresponding to the first ambient light sensor or an area corresponding to the second ambient light sensor when the electronic device is not bent.

Specifically, the first ambient light sensor 180L1 is taken as an example, that is, the first detected ambient light intensity output by the first ambient light sensor 180L1 is obtained in step S13, and at this time, the screen disturbance area when the electronic device 100 is not bent is the area corresponding to the first ambient light sensor 180L1 when the electronic device 100 is not bent. And then, determining the current display content of the screen interference area when the screen is not bent, and determining the screen interference value of the screen interference area when the screen is not bent according to the current display content. And finally, calculating the difference value between the first detection environment light intensity and the screen interference value of the screen interference area when the screen interference area is not bent, and obtaining the real environment light intensity.
