TECHNICAL FIELD

[0002] The present disclosure relates generally to the field of screen control technologies, and in particular, to a method, apparatus, electronic device, and storage medium for controlling a brightness of a screen.

BACKGROUND

[0003] In the related art, an electronic device, such as a mobile phone and a tablet, can automatically adjust the brightness of its screen according to a change in light brightness of the environment in which the electronic device is located. However, in the case where the light brightness of the environment does not change, if the user holds the electronic device horizontally, that is, the user holds opposite ends of the electronic device with hands where one end of the electronic device is provided with a photosensitive sensor, the photosensitive sensor of the electronic device may be blocked by a finger or the palm of the user, then the photosensitive sensor may misjudge that the light of the current environment changes, which triggers the automatic adjustment of the brightness of the screen of the electronic device to adapt the brightness of the screen to the current environment.

[0004] Therefore, in the related art, the screen brightness adjustment may still proceed under the condition that the ambient light intensity does not change, and the brightness mis-adjustment is easy to occur.

The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure.

[0022] It should be understood, although terms first, second, third and the like are used in the present disclosure to depict various information, such information is not restricted by these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information. Similarly, the second information may also be referred to as the first information. Depending on context, the word "if" used herein may be explained to "when" or "upon" or "in response to determining . . . ".

[0023] FIG. 1 is a flowchart of a method for controlling a brightness of a screen according to an exemplary embodiment of the present disclosure. As shown in FIG. 1, the method may be used in a terminal device, and includes the following steps.

[0024] In step 101, when a change in light intensity is detected, it is detected whether a photosensitive sensor of the terminal device is blocked.

[0025] In step 102, current brightness of the screen is maintained when it is detected that the photosensitive sensor is blocked.

[0026] The light intensity may be detected by the photosensitive sensor of the terminal device. When an electrical signal corresponding to the current light intensity detected by the photosensitive sensor is different from an electrical signal corresponding to the light intensity detected last time, a change of the light intensity may be detected.

[0027] The change in the light intensity detected by the photosensitive sensor is usually caused by a change in the actual light intensity of the environment or the occlusion of the photosensitive sensor. In order to determine the cause of the change in the detected light intensity so as to avoid mis-adjusting the brightness in the case where the intensity of the ambient light does not change, in the step 101, when it is detected that the light intensity changes, it is further detected whether the photosensitive sensor is blocked.

[0028] Therefore, when the change of the light intensity is detected, the present disclosure firstly detects whether the photosensitive sensor of the terminal device is blocked, and then determines whether it is necessary to adjust the brightness of the screen according to the detection result, rather than directly adjusting the brightness of the screen, thereby effectively avoiding adjusting the brightness of the screen due to the occlusion of the photosensitive sensor in the case where the ambient light intensity does not change; and it is advantageous to prevent the brightness from being mis-adjusted and the energy loss caused by the mis-adjustment, and to improve accuracy of control of the brightness of the screen. Moreover, even if the user grips the terminal device horizontally and blocks the photosensitive sensor, the screen maintains the original brightness, instead of becoming dark, thereby optimizing the user experience.

[0029] FIG. 2 is a flowchart illustrating a step of detecting whether a photosensitive sensor is blocked according to an exemplary embodiment of the present disclosure. As shown in FIG. 2, the step of detecting whether the photosensitive sensor is blocked includes the following steps.

[0030] In step 101a, it is detected whether the screen is in a landscape state.

[0031] In step 101b, it is detected whether a touch operation is performed on a first area and a second area of the screen. The first area is adjacent to the photosensitive sensor, and the second area is an area on the screen except the first area.

[0032] In step 101c, when the screen is in the landscape state and the touch operation is performed on the first area and the second area, it is determined that the photosensitive sensor is blocked.

[0033] In the landscape state, when the user touches the first area adjacent to the photosensitive sensor and the second area except the first area in the touch screen, the hand for touching the first area generally spans above the photosensitive sensor and falls on the first area, thereby blocking the photosensitive sensor, which causes the intensity of the light detected by the photosensitive sensor to be weakened. Therefore, the present disclosure determines whether the photosensitive sensor is blocked by detecting whether the screen is in a landscape state, and whether the touch operation is performed on the first area and the second area, thereby improving the detection accuracy of the occlusion of the photosensitive sensor, and improving the accuracy of control of the brightness of the screen; and, in the detection process, it is sufficient only to apply the gravity sensor and the touch sensor, therefore the detection is easy to implement and the detection process is simple, which is beneficial to improve the detection efficiency.

[0034] In this embodiment, the order of the step 101a and the step 10b is not limited.

[0035] In the step 101a, the landscape state of the screen may be detected by the gravity sensor of the terminal device. FIG. 3 is a schematic diagram showing a screen of a terminal device in a portrait state according to an exemplary embodiment of the present disclosure; and FIG. 4 is a schematic diagram showing a screen of a terminal device in a landscape state according to an exemplary embodiment of the present disclosure.

[0036] In the step 101b, the touch operation of the first area and the second area may be detected by the touch sensor of the terminal device, such as a touch screen of the terminal device. In order to determine whether the touch operation occurs in the first area or the second area, the first area and the second area of the screen may be pre-divided, e.g., by the developer in the development stage, and coordinates of the first area and the second area are saved in the terminal device.

[0037] FIG. 5 is a schematic diagram of a first area and a second area of a screen according to an exemplary embodiment of the present disclosure. As shown in FIG. 5, the screen includes a photosensitive sensor A, a first area B1 represented by a dotted frame, and a second area B2 except the dotted frame. In other embodiments, the second area may be a portion of other area than the first area and separated from the first area, as shown in FIG. 6. FIG. 6 is a schematic diagram showing a first area C1 and another second area C2 of the screen according to an exemplary embodiment of the present disclosure, wherein the first area C1 is represented a first dotted frame, and the second area C2 is represented by a second dotted frame.

[0038] In an embodiment, in order to improve the detection accuracy of the touch operation and the accuracy of the screen brightness adjustment, in the step 101c (FIG. 2), before determining that the photosensitive sensor is blocked, the method further includes the following steps: detecting report rates of the touch operation for the first area and the second area; comparing the report rate of the first area is compared with a preset first report threshold, and the report rate of the second area with a preset second report threshold; and determining whether the photosensitive sensor is blocked according to the comparison results.

[0039] In this embodiment, the report rate may be detected by the touch sensor of the terminal device, such as a touch screen of the terminal device. The first report threshold and the second report threshold may be preset, e.g., by a developer during a development phase, or may be set by a user according to usage. The first report threshold may be equal to or approximately equal to the second report threshold such that, for example, a difference between the first report threshold and the second report threshold being less than 1. The difference being less than 1 is only an example. In other embodiments, other reasonable values may also be taken, and the value may be obtained by triggering a corresponding instruction when clicking controls displayed in the first area and the second area of the screen by fingers of both hands of the user while interacting through the screen.

[0040] In an embodiment, when the comparison result is: the report rate of the first area is greater than or equal to the first report threshold, and the report rate of the second area is greater than or equal to the second report threshold, it is determined that the photosensitive sensor is blocked.

[0041] In an embodiment, in the landscape state, even if the touch operation is not detected in the first area and/or the second area, the user may block the photosensitive sensor by hands when using the terminal device. For example, when the user holds the terminal device to watch the video with both hands or one hand, the hand near the first area may block the photosensitive sensor, as shown in FIG. 7. FIG. 7 is a schematic diagram illustrating that the user's hand blocks the photosensitive sensor according to an exemplary embodiment of the present disclosure. Therefore, in order to realize the detection of whether the photosensitive sensor is blocked in this case, so as to further improve the accuracy of adjusting the brightness of the screen, the step of detecting whether the photosensitive sensor is blocked may further include the following steps, as shown in FIG. 8, which is a flowchart illustrating a step of detecting whether the photosensitive sensor is blocked according to an exemplary embodiment of the present disclosure.

[0042] In step 101d: when the screen is in the landscape state and there is no touch operation on the first area and/or the second area, the distance sensor detects whether there is an object within a preset distance threshold; wherein the distance sensor is disposed adjacent to the photosensitive sensor.

[0043] In step 101f: it is determined whether the photosensitive sensor is blocked according to the detection result.

[0044] In an embodiment, in the portrait state, the phenomenon of blocking the photosensitive sensor by the hand may also occur during use of the terminal device by the user. In order to also detect whether the photosensitive sensor is blocked in the portrait mode, and to eliminate the situation in which the distance sensor detects the object within the preset distance threshold due to the close contact with the earpiece (i.e., in this case, it is not regarded as the photosensitive sensor being blocked), the control accuracy of the brightness of the screen is further improved. As shown in FIG. 8, the step of detecting whether the photosensitive sensor is blocked may further include the following steps.

[0045] In step 101e: when the screen is not in the landscape mode (i.e., in a portrait state), it is detected whether a call application is running.

[0046] When the call application is running, a result that the photosensitive sensor is unblocked is outputted.

[0047] When the call application is not running, the distance sensor detects whether there is an object within a preset distance threshold.

[0048] In step 101f: it is determined whether the photosensitive sensor is blocked according to the detection result.

[0049] In the step 101d or the step 101e, in the step of determining whether the photosensitive sensor is blocked according to the detection result, the detection result includes the following two situations. In the first situation, the distance sensor detects that there is the object existing within the distance threshold; and in the second situation, the distance sensor does not detect the presence of the object within the distance threshold. Under the first detection result, it is determined that the photosensitive sensor is blocked; and under the second detection result, it is determined that the photosensitive sensor is not blocked.

[0050] In the embodiment, the distance sensor is disposed adjacent to the photosensitive sensor, and if there is an object being too close to the distance sensor, i.e., the distance sensor detects the existence of an object within the distance threshold, the photosensitive sensor is likely blocked. Therefore, whether the photosensitive sensor is blocked may be determined by the detection result of the distance sensor within the distance threshold. The distance threshold may be acquired by the developer according to experiments, and the specific acquisition manner may be obtained by combining the present disclosure with the related art, which is not elaborated herein.

[0051] FIG. 9 is a flowchart illustrating a step of detecting whether the photosensitive sensor is blocked according to another exemplary embodiment of the present disclosure. As shown in FIG. 9, the step of detecting whether the photosensitive sensor is blocked includes the following steps.

[0052] In step 101c1', it is detected whether the screen is in a landscape state.

[0053] In step 101c2', the distance sensor detects whether an object exists within a preset distance threshold. The distance sensor is disposed adjacent to the photosensitive sensor.

[0054] In step 101c3', it is determined whether the photosensitive sensor is blocked based on the detection result.

[0055] In the embodiments shown in the steps 101c1' to 101c3', for the understanding of the landscape state and the distance threshold, reference may be made to the foregoing description of the landscape state and the distance threshold, and details are not described herein.

[0056] The step 101c3' may include the following steps.

[0057] When it is detected that the screen is in the landscape state and the distance sensor detects an object within the preset distance threshold, it is determined that the photosensitive sensor is blocked.

[0058] When it is detected that the screen is not in the landscape state, and/or the distance sensor does not detect an object within the preset distance threshold, it is determined that the photosensitive sensor is unblocked.

[0059] Thereby, by detecting whether the screen is in the landscape state and detecting whether there is an object within the preset distance threshold by the distance sensor, and then determining whether the photosensitive sensor is blocked based on the detection results, the detection step is simplified. Furthermore, the distance sensor and the photosensitive sensor are disposed adjacently, and as long as the object is detected within the preset distance threshold by the distance sensor in the landscape state (to exclude the condition that the distance sensor detects the object within the preset distance threshold due to the close contact with the earpiece), the object may block the photosensitive sensor, and when no object is detected within the preset distance threshold, there is no blocking the photosensitive sensor, the detection accuracy of the photosensitive sensor being blocked or not can be ensured, the control accuracy of the brightness of the screen is improved, and the user experience is optimized.

[0060] In an embodiment, based on any of the foregoing embodiments, the method for controlling a brightness of a screen of the present disclosure may further include: when it is detected that the photosensitive sensor is not blocked, the brightness of the screen is adjusted according to a current light intensity parameter.

[0061] In the embodiment, adjusting the brightness of the screen according to the current light intensity parameter may be implemented with a traditional method known from the related art, and details are not described herein.

[0062] Therefore, in the present disclosure, by adjusting the brightness of the screen according to the current light intensity parameter when the photosensitive sensor is not blocked, the brightness of the screen can be adjusted properly so as to adapt to the current use environment.

[0063] In an embodiment, before adjusting the brightness of the screen according to the current light intensity parameter, the following steps are further included: a first control and a second control are displayed on a current interface of the screen, wherein the first control is used to trigger an event of automatically adjusting the brightness of the screen, and the second control is used to trigger an event of canceling the automatic adjustment of the brightness of the screen; it is determined, according to the currently triggered control, whether to adjust the brightness of the screen according to the current light intensity parameter.

[0064] The above operation is performed when it is detected that the photosensitive sensor is unblocked.

[0065] FIG. 10 is a schematic diagram of an interface when the terminal device displays the first control and the second control according to an exemplary embodiment of the present disclosure. As shown in FIG. 10, the first control 1001 and the second control 1002 may be configured in a pop-up window, then when it is detected that the photosensitive sensor is not blocked, the pop-up window pops up. The pop-up window displays the text content, e.g., "The screen brightness auto-adjustment function is started after 5s", the first control 1001, and the second control 1002. The display content of the first control 1001 may be: "Confirm", and the display content of the second control 1002 may be: "Cancel". In other embodiments, instead of displaying the pop-up window, the content "Turn on the screen brightness auto-adjustment" may be displayed directly in the first control 1001, and the content "Cancel the screen brightness auto-adjustment" is displayed in the second control 1002. Thus, the user can clearly know the functions of the first control 1001 and the second control 1002 so as to trigger the desired control.

[0066] In the embodiment, when the user clicks on the first control 1001 to trigger an event of automatically adjusting the brightness of the screen, the system of the terminal device adjusts the brightness of the screen according to the current light intensity parameter detected by the photosensitive sensor. When the user clicks on the second control 1002 to trigger an event of cancelling the automatic adjustment of the brightness of the screen, the system of the terminal device does not perform the operation of adjusting the brightness of the screen, but maintains the current brightness to meet the current usage requirements of the user.

[0067] In the present disclosure, by displaying the controls for controlling the automatic adjustment of the brightness of the screen to the user before adjusting the brightness of the screen according to the current light intensity parameter, the user can determine whether to adjust the brightness of the screen according to the needs of the user, which is beneficial to further optimize the user experience.

[0068] In an embodiment, based on any of the foregoing embodiments, when it is detected or determined that the photosensitive sensor is blocked, the method for adjusting the brightness of the screen of the present disclosure may further include the following step: a first adjustment threshold is updated to a second adjustment threshold, where the second adjustment threshold is greater than the first adjustment threshold, and the first adjustment threshold or the second adjustment threshold is used to trigg an event of automatic adjustment of brightness of the screen.

[0069] The first adjustment threshold and the second adjustment threshold correspond to a degree of change of the light intensity detected by the photosensitive sensor. For example, assuming that the light intensity detected by the photosensitive sensor last time is a, and the light intensity detected this time is b, then only if an absolute value of a difference between b and a is greater than or equal to the first adjustment threshold or the second adjustment threshold, the event of automatically adjusting the brightness of the screen is triggered.

[0070] Thus, in the embodiment, when the photosensitive sensor is occluded, by updating the adjustment threshold for triggering the event of automatically adjusting the brightness of the screen, the adjustment threshold is increased, thereby facilitating further preventing the mis-adjustment of brightness of the screen when the ambient light intensity does not change while the photosensitive sensor is occluded.
