Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and in particular to methods, apparatus, electronic devices and storage media for adjusting backlight brightness. Background Technology

[0002] The backlight brightness of electronic devices (such as mobile phones) is generally determined by the light intensity detected by a light sensor. When the light intensity is high, the backlight brightness of the electronic device's screen needs to be increased. Conversely, when the light intensity is low, the backlight brightness needs to be decreased. This allows the screen's backlight brightness to adapt to changes in ambient light. However, light sensors have a relatively small measurement angle, and the measured light intensity sometimes does not accurately reflect changes in ambient light. Moreover, when the light sensor is blocked, its measurement angle becomes even smaller, further failing to reflect the true state of ambient light.

[0003] Therefore, in many scenarios, even if the ambient light remains unchanged, changes in the measurement angle due to various reasons can cause electronic devices to frequently adjust the backlight brightness, affecting the user experience. Summary of the Invention

[0072] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0073] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0074] Figure 1 This is a flowchart illustrating a method for adjusting backlight brightness according to an exemplary embodiment, such as... Figure 1 As shown, the method is applied to an electronic device, and the method includes:

[0075] Step 11: Obtain the attitude parameters of the electronic device, wherein the attitude parameters include at least: parameters associated with the rotation of the electronic device;

[0076] Step 12: Obtain the light intensity, wherein the light intensity is the ambient light intensity detected by the light sensor of the electronic device;

[0077] Step 13: Determine whether to adjust the backlight brightness of the electronic device based on the light intensity and the posture parameters.

[0078] Here, the electronic device can be a terminal device with display functionality. This terminal device can be a mobile terminal, a desktop computer, or a smart home device, etc.; wherein, a mobile terminal can be a mobile phone, wearable device, tablet computer, or laptop computer; and a smart home device can be a television set, etc.

[0079] In one embodiment, the attitude parameters and / or light intensity of the electronic device may be acquired periodically.

[0080] In one embodiment, the period for acquiring the attitude parameters is determined based on the usage period of the electronic device.

[0081] In one embodiment, in response to the electronic device being in a first time period, it is determined that the period for acquiring the attitude parameters is greater than a period threshold; in response to the electronic device being in a second time period, it is determined that the period for acquiring the attitude parameters is less than the period threshold. Thus, the period for acquiring the attitude parameters can be adapted to the usage period of the electronic device.

[0082] For example, the first time period could be from 9:00 AM to 11:00 AM, during which the electronic device is less likely to be used and its posture is less likely to change; therefore, the period for acquiring the posture parameters can be set to be greater than a period threshold. As another example, the second time period could be from 7:00 PM to 8:00 PM, during which the electronic device is more likely to be used and its posture is less likely to change; therefore, the period for acquiring the posture parameters can be set to be less than a period threshold.

[0083] In one embodiment, the period for acquiring the light intensity is determined based on the usage period of the electronic device.

[0084] In one embodiment, in response to the electronic device being in a first time period, it is determined that the period for acquiring the light intensity is greater than a period threshold; in response to the electronic device being in a second time period, it is determined that the period for acquiring the attitude parameter is less than a period threshold.

[0085] For example, the first time period could be from 7 PM to 3 AM, which is nighttime and the probability of changes in ambient light is low, so the period for acquiring the attitude parameters can be set to be greater than a period threshold. As another example, the second time period could be from 9 AM to 6 PM, which is daytime and the probability of changes in ambient light is high, so the period for acquiring the attitude parameters can be set to be less than a period threshold.

[0086] In one embodiment, the parameter associated with the rotation of the electronic device may be the angle between a reference plane of the electronic device and a predetermined reference plane. Here, the reference plane may be the panel of the electronic device.

In response to the light intensity being less than a light intensity threshold and the rate of change of the heading angle being less than a rate of change threshold, it is determined that the backlight brightness of the electronic device will be adjusted.

[0094] In one embodiment, a reference attitude parameter may be determined based on different types of attitude parameters and their corresponding weight values; and the operation of adjusting the backlight brightness of the electronic device may be determined based on the reference attitude parameter.

[0095] In one embodiment, in response to the light intensity being less than a light intensity threshold and the reference attitude parameter being greater than a parameter threshold, it is determined that the backlight intensity of the electronic device will not be adjusted; in response to the light intensity being less than a light intensity threshold and the reference attitude parameter being less than a reference threshold, it is determined that the backlight intensity of the electronic device will be adjusted.

[0096] In one embodiment, the attitude parameters can be the average value of the attitude parameters obtained within a predetermined time period. This results in more accurate attitude parameters.

[0097] In one embodiment, the light intensity can be the average value of the light intensity obtained within a predetermined time period. Thus, the average value of the light intensity is obtained.

[0098] In one embodiment, in response to detecting that the electronic device is in a stationary state, an operation is determined whether to adjust the backlight brightness of the electronic device based on the light intensity and the attitude parameter.

[0099] In another embodiment, in response to detecting that the movement speed of the electronic device is less than a speed threshold, an operation to adjust the backlight brightness of the electronic device is determined based on the light intensity and the attitude parameters.

[0100] In the embodiments of this disclosure, the attitude parameters of the electronic device are obtained, wherein the attitude parameters include at least: parameters associated with the rotation of the electronic device; light intensity is obtained, wherein the light intensity is the ambient light intensity detected by the light sensor of the electronic device; and an operation to adjust the backlight brightness of the electronic device is determined based on the light intensity and the attitude parameters. Thus, the operation of adjusting the backlight brightness of the electronic device is determined jointly based on the light intensity and the attitude parameters. Compared to operations that only determine the adjustment of the backlight brightness based on the light intensity, this reduces the frequent adjustments to the backlight brightness caused by changes in the light intensity due to changes in the electronic device's attitude, which may not accurately reflect changes in ambient light, thereby improving the user experience.

Thus, the predetermined time can be adapted to the usage period.

[0117] For example, if the first time period is from 7 PM to 8 PM, which is the peak usage time for electronic devices and the probability of rotation is relatively high, then the predetermined time can be determined to be greater than the time threshold.
