[0035] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0036] Figure 1Fig. 1 is a schematic diagram of an application environment of a screen brightness control method in an embodiment. As shown in Figure 1 Fig. 1, the application environment includes a wearable device 110 and a server 120. In an embodiment, the wearable device 110 can execute the screen brightness control method provided in the present application alone. The wearable device 110 and the server 120 can also be used cooperatively to execute the screen brightness control method provided in the present application.

[0037] When the wearable device 110 and the server 120 are used cooperatively to execute the screen brightness control method provided in the present application, the wearable device 110 acquires wrist-lifting feature information corresponding to a wrist-lifting operation in response to the wrist-lifting operation. The wearable device 110 sends the wrist-lifting feature information to the server 120. The server 120 receives the wrist-lifting feature information and determines whether the wrist-lifting feature information satisfies a matching condition. In the case where the wrist-lifting feature information satisfies the matching condition, the server 120 returns the recognition result to the wearable device 110. The wearable device 110 determines a current first ambient light intensity in the case where the wrist-lifting feature information satisfies the matching condition, and sends the current first ambient light intensity to the server 120. The server 120 determines a target screen brightness corresponding to the current ambient light intensity, and returns the target screen brightness to the wearable device 110. The wearable device 110 receives the target screen brightness, and adjusts the screen brightness of the wearable device to the target screen brightness.

[0038] The wearable device 110 can be, but is not limited to, various smart bands and smart watches. The server 120 can be implemented by an independent server or a server cluster composed of multiple servers. The wearable device 110 and the server 120 can be directly or indirectly connected through wired or wireless communication, which is not limited in the present application.

[0039] Figure 2 Fig. 2 is a flowchart of a screen brightness control method in an embodiment. The screen brightness control method in the present embodiment is described by taking a wearable device running in an operating system as an example. As shown in Figure 1 Fig. 2, the screen brightness control method includes the following steps. Figure 2

[0040] Step 202: In response to a wrist-lifting operation, acquire wrist-lifting feature information corresponding to the wrist-lifting operation.

[0041] The wrist-lifting operation refers to an operation of lifting a wrist or an ankle upward. The wrist-lifting feature information refers to feature information collected in the process of lifting the wrist or the ankle upward, for example, the feature information includes at least one of a wrist-lifting amplitude, a wrist-lifting direction, and a rotation angle.

[0042] ​Specifically, the user wears the wearable device on the wrist, and when the user raises the wrist to use the wearable device, the wearable device can detect whether the user has the wrist-raising operation. In the case that the processor of the wearable device detects the wrist-raising operation of the user, the processor of the wearable device collects the feature information generated by the user during the wrist-raising operation in response to the wrist-raising operation.

[0043] In one embodiment, in response to the wrist-raising operation, the wrist-raising feature information corresponding to the wrist-raising operation is acquired, including: in response to the wrist-raising operation, the wrist-raising amplitude and the wrist-raising direction corresponding to the wrist-raising action are acquired; and the wrist-raising amplitude and the wrist-raising direction are taken as the feature information corresponding to the wrist-raising action.

[0044] Specifically, the processor of the wearable device acquires the acceleration information of the wearable device through the acceleration sensor or the gravity sensor in response to the wrist-raising operation, and determines the wrist-raising amplitude and the wrist-raising direction corresponding to the wrist-raising action based on the acceleration information of the wearable device. The processor of the wearable device takes the wrist-raising amplitude and the wrist-raising direction as the feature information corresponding to the wrist-raising action.

[0045] In one of the embodiments, in response to the wrist-raising operation, the wrist-raising feature information corresponding to the wrist-raising operation is acquired, including: in response to the wrist-raising operation, the wrist-raising amplitude, the wrist-raising direction, and the rotation angle corresponding to the wrist-raising action are acquired; and the wrist-raising amplitude, the wrist-raising direction, and the rotation angle are taken as the feature information corresponding to the wrist-raising action.

[0046] Specifically, the processor of the wearable device acquires the acceleration information of the wearable device through the acceleration sensor or the gravity sensor in response to the wrist-raising operation, and determines the wrist-raising amplitude and the wrist-raising direction corresponding to the wrist-raising action based on the acceleration information of the wearable device. Moreover, the processor of the wearable device detects the angular velocity information of the wearable device through the gyroscope, and determines the rotation angle corresponding to the wrist-raising action based on the angular velocity information. The processor of the wearable device takes the wrist-raising amplitude, the wrist-raising direction, and the rotation angle as the feature information corresponding to the wrist-raising action.

[0047] In step 204, in the case that the wrist-raising feature information meets the matching condition, the current first ambient light intensity is determined.

[0048] The matching condition includes at least one of the ambient light detection condition and the brightness adjustment condition. In the case that the matching condition includes the ambient light detection condition, in the case that the wrist-raising feature information meets the ambient light detection condition, the processor of the wearable device can detect the current ambient light intensity through the ambient light sensor, and take the detected ambient light intensity as the first ambient light intensity.

[0049] Further, the ambient light detection condition comprises that a matching degree between the wrist-lifting feature information and the preset feature information reaches a first matching degree, or the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach a second matching degree. Alternatively, a difference degree between the wrist-lifting feature information and the preset feature information is less than a first difference degree, or the difference degree between the wrist-lifting feature information and the preset feature information is less than the first difference degree and greater than a second difference degree.

[0050] The matching degree refers to a degree of feature similarity between the wrist-lifting feature information and the preset feature information, and the difference degree refers to a degree of feature difference between the wrist-lifting feature information and the preset feature information.

[0051] Specifically, the processor of the wearable device can acquire the preset feature information, compare the wrist-lifting feature information with the preset feature information, and calculate a matching degree between the wrist-lifting feature information and the preset feature information. In a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches a first matching degree, the processor of the wearable device can acquire a current first ambient light intensity through an ambient light sensor (ALS).

[0052] In one embodiment, the processor of the wearable device can acquire the preset feature information, compare the wrist-lifting feature information with the preset feature information, and calculate a difference degree between the wrist-lifting feature information and the preset feature information. In a case where the difference degree between the wrist-lifting feature information and the preset feature information reaches a first difference degree, the processor of the wearable device can acquire a current first ambient light intensity through an ambient light sensor. Further, in a case where the difference degree between the wrist-lifting feature information and the preset feature information is less than the first difference degree and greater than a second difference degree, the current first ambient light intensity is acquired through the ambient light sensor.

[0053] In step 206, a target screen brightness corresponding to the first ambient light intensity is determined, and the screen brightness of the wearable device is adjusted to the target screen brightness.

[0054] The screen brightness refers to a brightness degree of the screen.

[0055] Specifically, after the processor of the wearable device determines the current first ambient light intensity, a mapping relationship between the ambient light intensity and the screen brightness can be acquired. Based on the mapping relationship, the processor of the wearable device can acquire a target screen brightness corresponding to the current first ambient light intensity. The processor of the wearable device can determine a current screen brightness, and adjust the current screen brightness to the target screen brightness.

[0056] It can be understood that the wearable device processor obtains the mapping relationship between the ambient light intensity and the screen brightness before the step of determining the target screen brightness corresponding to the first ambient light intensity. For example, the step of determining the current first ambient light intensity can be performed after the step of determining the current first ambient light intensity, or before the step of determining the current first ambient light intensity, or simultaneously, without too many limitations here.

[0057] In one embodiment, the matching condition includes an ambient light detection condition and a brightness adjustment condition; and the determining the current first ambient light intensity in the case that the wrist-lifting feature information meets the matching condition includes: determining the current first ambient light intensity in the case that the wrist-lifting feature information meets the ambient light detection condition.

[0058] The adjusting the screen brightness of the wearable device to the target screen brightness includes: adjusting the screen brightness of the wearable device to the target screen brightness in the case that the wrist-lifting feature information meets the brightness adjustment condition.

[0059] Specifically, the brightness adjustment condition includes that a matching degree between the wrist-lifting feature information and the preset feature information reaches a second matching degree, or a difference degree between the wrist-lifting feature information and the preset feature information is less than a second difference degree.

[0060] In one embodiment, the user can select whether to start the function of automatically adjusting the screen brightness, and when the user triggers the automatic adjustment function of the screen brightness, the wearable device starts the automatic adjustment function in response to the triggering operation of the user. The wearable device that starts the automatic adjustment function can monitor or detect whether the user has a wrist-lifting operation in real time.

[0061] In one embodiment, the brightness level of the screen brightness is set in advance, and the mapping relationship between the ambient light intensity and the brightness level is constructed. After the processor of the wearable device determines the current first ambient light intensity, the mapping relationship between the ambient light intensity and the brightness level can be obtained. Based on the mapping relationship, the processor of the wearable device can obtain the brightness level corresponding to the first ambient light intensity. The processor of the wearable device can determine the current screen brightness, and adjust the current screen brightness to the target screen brightness corresponding to the brightness level.

[0062] The screen brightness control method applied to the wearable device in the embodiment responds to the wrist lifting operation, acquires wrist lifting feature information corresponding to the wrist lifting operation, and determines the current first ambient light intensity in the case where the wrist lifting feature information meets the matching condition, so as to perform ambient light detection in the process of the user lifting the wrist and determine the target screen brightness suitable for the wearable device under the current ambient light intensity. Before the user completes the wrist lifting operation, the screen brightness of the wearable device is adjusted to the target screen brightness corresponding to the current ambient light intensity, so that the screen brightness of the wearable device conforms to the current ambient brightness, thereby avoiding eye discomfort caused by too bright or too dark screen brightness when the user lifts the wrist to look at the wearable device.

[0063] In one embodiment, in the case where the wrist lifting feature information meets the matching condition, the current ambient light intensity is determined, including: in the case where the matching degree between the wrist lifting feature information and the preset feature information reaches a first matching degree, the current first ambient light intensity is determined.

[0064] Adjusting the screen brightness of the wearable device to the target screen brightness includes: in the case where the matching degree between the wrist lifting feature information and the preset feature information reaches a second matching degree, adjusting the screen brightness of the wearable device to the target screen brightness; the first matching degree is less than the second matching degree.

[0065] Specifically, in the case where the matching degree between the wrist lifting feature information and the preset feature information reaches the first matching degree, the processor of the wearable device can collect the current first ambient light intensity through the ambient light sensor. Further, in the case where the matching degree between the wrist lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, the current first ambient light intensity is collected through the ambient light sensor.

[0066] In the case where the matching degree between the wrist lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, the processor of the wearable device can continue to detect the matching degree between the wrist lifting feature information and the preset feature information. The processor of the wearable device can acquire a mapping relationship between the ambient light intensity and the screen brightness. In the case where the matching degree between the wrist lifting feature information and the preset feature information reaches the second matching degree, the processor of the wearable device can acquire the target screen brightness corresponding to the current first ambient light intensity based on the mapping relationship. The processor of the wearable device adjusts the current screen brightness to the target screen brightness.

[0067] In the embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree, it indicates that the user is in the process of lifting the wrist, and the current first ambient light intensity is determined in advance in the process of lifting the wrist of the user, so that the target screen brightness corresponding to the current first ambient light intensity can be determined in the process of lifting the wrist of the user. When the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, it indicates that the wrist-lifting action of the user has been completed or is about to be completed, and the screen brightness of the wearable device can be directly adjusted to the target screen brightness, so that the screen brightness of the wearable device displayed by the user conforms to the brightness of the current environment, avoiding discomfort to the eyes of the user, thereby improving the accuracy and speed of screen brightness control.

[0068] In one embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree, the current ambient light intensity is determined, comprising: when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, the current ambient light intensity is determined.

[0069] Specifically, the processor of the wearable device can acquire the preset feature information, compare the wrist-lifting feature information and the preset feature information to calculate the matching degree between the wrist-lifting feature information and the preset feature information. The first matching degree and the second matching degree are acquired, and the matching degree between the wrist-lifting feature information and the preset feature information is compared with the first matching degree and the second matching degree respectively. When the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, the processor of the wearable device can acquire the current ambient light intensity through the ambient light sensor.

[0070] In the embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, it indicates that the user is in the process of lifting the wrist, and the current ambient light intensity is detected in advance, and the screen brightness required to be adjusted by the wearable device under the current environment is determined in the process of lifting the wrist of the user, so that the screen brightness of the wearable device can be quickly adjusted.

[0071] In one embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, the screen brightness of the wearable device is adjusted to the target screen brightness, comprising: within the preset time length, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, the screen brightness of the wearable device is adjusted to the target screen brightness.

[0072] Specifically, the processor of the wearable device can calculate the matching degree between the wrist-lifting feature information and the preset feature information in real time or at a timing. When the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree within the preset time length, the screen brightness of the wearable device is adjusted to the target screen brightness.

[0073] In the embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree within the preset time length, it indicates that the wrist-lifting action of the user has been completed or is about to be completed, and then the screen brightness of the wearable device is adjusted to the target screen brightness, so that the screen brightness of the wearable device can be quickly adjusted to conform to the current ambient light intensity.

[0074] In one embodiment, the timing can be started when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree, to determine whether the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree within the preset time length.

[0075] In other embodiments, the processor of the wearable device can start the timing when the wrist-lifting feature information corresponding to the wrist-lifting operation is acquired, to determine whether the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree within the preset time length.

[0076] In one embodiment, the method further includes: in the case where the matching degree between the wrist-lifting feature information and the preset feature information does not reach the second matching degree within the preset time length, not performing the screen-on operation.

[0077] Specifically, in the case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree, the timing can be started, and the matching degree between the wrist-lifting feature information and the preset feature information is detected in real time. In the case where the matching degree between the wrist-lifting feature information and the preset feature information does not reach the second matching degree within the preset time length, it indicates that the wrist-lifting operation is a false operation, and then the screen brightness adjustment and the screen-on operation are not performed.

[0078] In one embodiment, the method further includes: in the case where the matching degree between the wrist-lifting feature information and the preset feature information does not reach the second matching degree within the preset time length, not performing the screen-on operation, and returning to the step of acquiring the wrist-lifting feature information corresponding to the wrist-lifting operation in response to the wrist-lifting operation and continuing to execute.

[0079] Specifically, the processor of the wearable device can calculate the matching degree between the wrist-lifting feature information and the preset feature information in real time or at a fixed time. When the matching degree between the wrist-lifting feature information and the preset feature information does not reach the second matching degree within a preset time length, it is indicated that the wrist-lifting operation is a false operation, and the screen brightness adjustment and the screen-on operation are not performed, thereby avoiding the consumption of resources. The processor of the wearable device can return to the step of obtaining the wrist-lifting feature information corresponding to the wrist-lifting operation and continue to execute, thereby realizing the automatic detection of the wrist-lifting operation of the user and accurately adjusting the screen brightness of the wearable device according to the current ambient light.

[0080] In one embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, adjusting the screen brightness of the wearable device to the target screen brightness comprises: when the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, adjusting the screen brightness of the wearable device to the target screen brightness and performing the screen-on operation.

[0081] Specifically, the user starts the wrist-lifting screen-on function, and when the user lifts the wrist, the wearable device performs the screen-on operation, and in other cases, the wearable device is in an automatic screen-off state. When the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, the wearable device adjusts the current screen brightness to the target screen brightness and performs the screen-on operation.

[0082] In this embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, it is indicated that the user is in the process of lifting the wrist, and the current ambient light intensity is detected in advance, so that the screen brightness required by the wearable device in the current environment can be determined in advance before the user completes the wrist-lifting operation. When the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, it is indicated that the wrist-lifting action of the user has been completed or is about to be completed, and the screen brightness of the wearable device can be adjusted to the target screen brightness first, and then the screen-on operation is performed, so that the target screen brightness is directly displayed after the screen is turned on. The method of this embodiment can avoid the situation that the screen brightness is not suitable for the brightness of the current environment, resulting in that the screen is too bright or too dark in the instant of screen-on, causing the user's eyes to be uncomfortable.

[0083] In one embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, adjusting the screen brightness of the wearable device to the target screen brightness comprises: when the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, detecting the current screen state of the wearable device; and when the current screen state of the wearable device is the screen-off state, performing the screen-on operation, wherein the screen brightness when the screen is turned on is the target screen brightness.

[0084] Specifically, the user enables the wrist-lifting screen-on function, and the wearable device performs the screen-on operation when the user lifts the wrist, and the wearable device is in the automatic screen-off state in other cases. In a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches a second matching degree, it is indicated that the wrist-lifting action of the user has been completed or is about to be completed, and then the processor of the wearable device can detect the current screen state. The screen state includes the screen-on state or the screen-off state. In a case where the current screen state of the wearable device is the screen-off state, the processor of the wearable device can perform the screen-on operation. Moreover, the screen brightness of the wearable device when the screen is on is the target screen brightness corresponding to the first ambient light intensity.

[0085] It can be understood that the wearable device has determined the target screen brightness corresponding to the first ambient light intensity before performing the screen-on operation, and then the wearable device can directly use the target screen brightness to perform the screen-on operation. The wearable device can also adjust the screen brightness of the wearable device to the target screen brightness in a case where the current screen state of the wearable device is the screen-off state, and then perform the screen-on operation.

[0086] In one embodiment, in a case where the current screen state of the wearable device is the screen-off state, performing the screen-on operation includes: adjusting the screen brightness of the wearable device to the target screen brightness in a case where the current screen state of the wearable device is the screen-off state, and then performing the screen-on operation.

[0087] In the embodiment, in a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, it is indicated that the user is in the wrist-lifting process, and then the current ambient light intensity is detected in advance, so that the screen brightness required to be adjusted by the wearable device in the current environment can be determined in advance before the wrist-lifting operation of the user is completed. In a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, it is indicated that the wrist-lifting action of the user has been completed or is about to be completed, and then the screen-on operation can be directly performed using the target screen brightness, so that the screen-on operation directly shows the target screen brightness, and the efficiency of screen brightness adjustment is improved.

[0088] In one embodiment, in a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, adjusting the screen brightness of the wearable device to the target screen brightness includes:

[0089] In a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, the current screen state of the wearable device is detected; in a case where the current screen state of the wearable device is the screen-off state, the screen-on operation is performed, and the screen brightness of the wearable device is adjusted to the target screen brightness.

[0090] Specifically, in a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, it indicates that the wrist-lifting action of the user has been completed or is about to be completed, and then the processor of the wearable device can detect the current screen state. The screen state includes a screen-on state or a screen-off state. In a case where the current screen state of the wearable device is the screen-off state, the processor of the wearable device can perform a screen-on operation, and the screen brightness used when the screen is turned on can be the default screen brightness or the screen brightness used when the screen was turned off last time, and the screen brightness is adjusted to the target screen brightness.

[0091] In the embodiment, in a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, it indicates that the user is in the process of lifting the wrist, and then the current ambient light intensity is detected in advance, so that the screen brightness required by the wearable device in the current environment can be determined in advance before the user completes the wrist-lifting operation. In a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, it indicates that the wrist-lifting action of the user has been completed or is about to be completed, and then it is determined whether the wearable device is in the screen-off state. When in the screen-off state, the screen-on operation can be performed and adjusted to the target screen brightness, so that the screen-on can quickly adjust the screen brightness of the wearable device to the target screen brightness that meets the current ambient brightness.

[0092] In one embodiment, in a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, adjusting the screen brightness of the wearable device to the target screen brightness includes:

[0093] In a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, the current screen state of the wearable device is detected; in a case where the current screen state of the wearable device is the screen-off state, the screen brightness of the wearable device is adjusted to the target screen brightness, and the screen-on operation is performed.

[0094] Specifically, in a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, it indicates that the wrist-lifting action of the user has been completed or is about to be completed, and then the processor of the wearable device can detect the current screen state. In a case where the current screen state of the wearable device is the screen-off state, the processor of the wearable device can adjust the current screen brightness to the target screen brightness and perform the screen-on operation.

[0095] In the embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, it indicates that the user is in the wrist-lifting process, and the current ambient light intensity is detected in advance, so that the screen brightness required by the wearable device in the current environment can be determined in advance before the user completes the wrist-lifting operation. When the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, it indicates that the wrist-lifting action of the user has been completed or is about to be completed, and the screen brightness of the wearable device is adjusted to the target screen brightness in the screen-off state, and then the screen-on operation is performed, so that the target screen brightness is directly displayed after the screen is turned on. The method of the embodiment can avoid the situation that the screen brightness is not suitable for the brightness of the current environment, and the user's eyes are uncomfortable due to the over-brightness or over-darkness of the screen at the moment of turning on the screen.

[0096] In one embodiment, as shown in FIG. 3, Figure 3 When the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree, the first ambient light intensity of the current environment is determined, including:

[0097] Step 302, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree, the current screen state of the wearable device is determined.

[0098] Specifically, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree and does not reach the second matching degree, it indicates that the user is in the wrist-lifting process, and the processor of the wearable device can detect that the current screen state is in the screen-on state or the screen-off state.

[0099] Step 304, when the current screen state of the wearable device is in the screen-on state, the screen leakage amount of the wearable device and the second ambient light intensity in the screen-on state are obtained.

[0100] The second ambient light intensity is the ambient light intensity directly obtained by the ambient light sensor in the current environment. The first ambient light intensity is the actual ambient light intensity in the current environment, that is, the ambient light intensity excluding the screen leakage amount. It can be understood that in the screen-off state, the screen leakage amount is zero, and the first ambient light intensity in the screen-off state is equal to the second ambient light intensity.

[0101] Specifically, when the current screen state of the wearable device is in the screen-on state, the ambient light intensity detected by the ambient light sensor of the wearable device further includes the screen leakage amount generated by the screen of the wearable device. The processor of the wearable device can detect the second ambient light intensity in the screen-on state through the ambient light sensor, and obtain the current screen leakage amount.

[0102] At step 306, the second ambient light intensity in the screen-on state and the screen leakage light amount are used to determine the current first ambient light intensity.

[0103] Specifically, the processor of the wearable device can determine the difference between the second ambient light intensity in the screen-on state and the screen leakage light amount as the current first ambient light intensity.

[0104] In one embodiment, the processor of the wearable device can obtain a calibration coefficient corresponding to the screen leakage light amount, and calculate the product of the screen leakage light amount and the corresponding calibration coefficient. The processor of the wearable device can determine the difference between the second ambient light intensity in the screen-on state and the product as the current first ambient light intensity.

[0105] In the present embodiment, when the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree but does not reach the second matching degree, it indicates that the user is in the process of lifting the wrist, and then the screen can be detected to determine whether it is in the screen-on state. When the screen is in the screen-on state, the screen leakage light amount of the wearable device and the second ambient light intensity in the screen-on state are detected to exclude the influence of the screen leakage light amount on the current ambient light intensity, and the current first ambient light intensity is accurately detected. Based on the accurately detected ambient light intensity, the screen brightness of the wearable device can be accurately adjusted to adapt to the current ambient brightness.

[0106] In one embodiment, when the current screen state of the wearable device is in the screen-on state, the screen leakage light amount of the wearable device is obtained, including:

[0107] When the current screen state of the wearable device is in the screen-on state, the current screen picture displayed by the wearable device and the current screen brightness corresponding to the current screen picture are determined, and the screen leakage light amount corresponding to the combination of the current screen picture and the current screen brightness is obtained based on the mapping relationship between the combination of the screen picture and the screen brightness and the screen leakage light amount.

[0108] Specifically, the screen leakage light amount corresponding to different combinations of screen pictures and screen brightnesses is preset to construct the mapping relationship between the combination of the screen picture and the screen brightness and the screen leakage light amount. For example, (screen picture 1, screen brightness 1) corresponds to screen leakage light amount 1, (screen picture 1, screen brightness 2) corresponds to screen leakage light amount 2, (screen picture 2, screen brightness 2) corresponds to screen leakage light amount 3, and the like, but not limited thereto.

[0109] In the case that the current screen state of the wearable device is a bright screen state, the processor of the wearable device determines the displayed current screen picture and acquires the current screen brightness corresponding to the current screen picture. The processor of the wearable device can acquire a mapping relationship between the combination of the screen picture and the screen brightness and the screen light leakage amount, and acquire the screen light leakage amount corresponding to the combination of the current screen picture and the current screen brightness based on the mapping relationship.

[0110] In this embodiment, the mapping relationship between the combination of the screen picture and the screen brightness and the screen light leakage amount is constructed in advance, and the corresponding screen light leakage amount is directly acquired through the mapping relationship when needed, so that the step of calculating the screen light leakage amount is omitted, and the power consumption is reduced. Moreover, the screen light leakage amount does not need to be calculated by backstepping after being fitted by a formula, and the obtained screen light leakage amount is more accurate.

[0111] In one embodiment, before acquiring the wrist-lifting feature information corresponding to the wrist-lifting operation in response to the wrist-lifting operation, the method further includes: acquiring acceleration information of the wearable device, and determining that the wearable device is in the wrist-lifting process in the case that the acceleration information meets a preset wrist-lifting condition.

[0112] Specifically, the preset wrist-lifting condition includes preset acceleration information generated in the wrist-lifting process and acquired in advance. The processor of the wearable device detects the acceleration information of the wearable device through a gravity sensor or an acceleration sensor. The detected acceleration information is compared with the preset acceleration information, and it is determined that the wearable device is in the wrist-lifting process of the user in the case that the detected acceleration information matches the preset acceleration information.

[0113] Further, the preset acceleration information can include a preset acceleration range, and the acceleration information of the wearable device is the detected acceleration. When the detected acceleration is within the preset acceleration range, it indicates that the acceleration information meets the preset wrist-lifting condition, and it is determined that the wearable device is in the wrist-lifting process of the user.

[0114] Whether the detected acceleration information of the wearable device meets the preset wrist-lifting condition can directly and quickly determine whether the user is in the wrist-lifting process.

[0115] In one embodiment, before acquiring the wrist-lifting feature information corresponding to the wrist-lifting operation in response to the wrist-lifting operation, the method further includes:

[0116] acquiring acceleration information and angular velocity information of the wearable device, and determining that the wearable device is in the wrist-lifting process in the case that the acceleration information and the angular velocity information meet a preset wrist-lifting condition.

[0117] The preset wrist-lifting condition includes preset angular velocity information and preset acceleration information acquired in the wrist-lifting process.

[0118] Specifically, the processor of the wearable device detects acceleration information of the wearable device through a gravity sensor or an acceleration sensor. The processor of the wearable device detects angular velocity information of the wearable device through a gyroscope.

[0119] Further, three-axis acceleration is detected through the gravity sensor or the acceleration sensor, and components of each axis are integrated in a time dimension to obtain three-axis acceleration information. Three-axis angular velocity is detected through the gyroscope, and components of each axis are integrated in the time dimension to obtain three-axis angular velocity information.

[0120] The processor of the wearable device can obtain preset angular velocity information and preset acceleration information included in the preset wrist-lifting condition, compare the detected angular velocity information with the preset angular velocity information, and compare the detected acceleration information with the preset angular velocity information. When the acceleration information of the wearable device satisfies the preset acceleration information and the angular velocity information satisfies the preset angular velocity information, it is determined that the wrist-lifting condition is satisfied, and it is determined that the wearable device is in the user wrist-lifting process.

[0121] In one embodiment, the preset acceleration information includes a preset acceleration range, and the preset angular velocity information includes a preset angular velocity range. The processor of the wearable device can compare the detected angular velocity and acceleration with the preset angular velocity range and the preset acceleration range, respectively. In a case where the detected angular velocity is within the preset angular velocity range and the acceleration is within the preset acceleration range, it is determined that the wearable device is in the user wrist-lifting process.

[0122] In this embodiment, whether the acceleration information and the angular velocity information of the wearable device satisfy the preset wrist-lifting condition can accurately detect whether the user is in the wrist-lifting process. Moreover, the acceleration information and the angular velocity information are used simultaneously to improve the accuracy of detection.

[0123] In one embodiment, as shown in Figure 4 a screen brightness control method is provided, including:

[0124] Step 402, in response to the wrist-lifting operation, obtaining wrist-lifting feature information corresponding to the wrist-lifting operation to calculate a matching degree between the wrist-lifting feature information and preset feature information.

[0125] Step 404, in a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches a first matching degree B and does not reach a second matching degree A, step 406 is executed, that is, the current first ambient light intensity is detected through the ambient light sensor, and the target screen brightness L corresponding to the current first ambient light intensity is determined. Then, step 408 is executed.

[0126] In a case where the matching degree between the wrist-lifting feature information and the preset feature information does not reach the first matching degree, the step of obtaining the wrist-lifting feature information corresponding to the wrist-lifting operation in response to the wrist-lifting operation is returned and the execution is continued, that is, the step 402 is returned and the execution is continued.

[0127] In a case where the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, the step 410 is executed, that is, the screen brightness of the wearable device is adjusted to the target screen brightness L, and the screen-on operation is executed.

[0128] In a case where the matching degree between the wrist-lifting feature information and the preset feature information does not reach the first matching degree, the step of obtaining the wrist-lifting feature information corresponding to the wrist-lifting operation in response to the wrist-lifting operation is returned and the execution is continued, that is, the step 402 is returned and the execution is continued.

[0129] In one embodiment, a screen brightness control method is provided, comprising:

[0130] In a case where the matching degree between the wrist-lifting feature information and the preset feature information does not reach the first matching degree, the step of obtaining the wrist-lifting feature information corresponding to the wrist-lifting operation in response to the wrist-lifting operation is returned and the execution is continued, that is, the step 402 is returned and the execution is continued.

[0131] In a case where the matching degree between the wrist-lifting feature information and the preset feature information does not reach the first matching degree, the step of obtaining the wrist-lifting feature information corresponding to the wrist-lifting operation in response to the wrist-lifting operation is returned and the execution is continued, that is, the step 402 is returned and the execution is continued.

[0132] In a case where the matching degree between the wrist-lifting feature information and the preset feature information does not reach the first matching degree, the step of obtaining the wrist-lifting feature information corresponding to the wrist-lifting operation in response to the wrist-lifting operation is returned and the execution is continued, that is, the step 402 is returned and the execution is continued.

[0133] In a case where the current screen state of the wearable device is the screen-on state, the steps (a4) to (a8) are executed, as follows:

[0134] In a case where the current screen state of the wearable device is the screen-on state, the steps (a4) to (a8) are executed, as follows:

[0135] In a case where the current screen state of the wearable device is the screen-on state, the steps (a4) to (a8) are executed, as follows:

[0136] In a case where the current screen state of the wearable device is the screen-on state, the steps (a4) to (a8) are executed, as follows:

[0137] Step (a7), determining the target screen brightness corresponding to the current first ambient light intensity.

[0138] Step (a8), in the case that the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree within the preset time length, adjusting the screen brightness of the wearable device to the target screen brightness.

[0139] In the case that the current screen state of the wearable device is the screen-off state, steps (a9) to (a11) are performed, as follows:

[0140] Step (a9), detecting the current first ambient light intensity through the ambient light sensor in the case that the current screen state of the wearable device is the screen-off state.

[0141] Step (a10), determining the target screen brightness corresponding to the current first ambient light intensity.

[0142] Step (a11), in the case that the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, adjusting the screen brightness of the wearable device to the target screen brightness and performing the screen-on operation.

[0143] In the embodiment, in the case that the matching degree between the wrist-lifting feature information and the preset feature information reaches the first matching degree, it indicates that the user is in the wrist-lifting process, and then the current screen-on state or screen-off state can be detected.

[0144] When in the screen-on state, the corresponding screen leakage amount can be obtained through the combination of the current screen picture and the current screen brightness displayed, so as to exclude the influence of the screen leakage amount on the current ambient light intensity, and accurately detect the current first ambient light intensity. Based on the pre-determined current first ambient light intensity, the target screen brightness corresponding to the current ambient light intensity can be pre-determined. In the case that the matching degree between the wrist-lifting feature information and the preset feature information reaches the second matching degree, it indicates that the wrist-lifting action of the user has been completed, and then the screen brightness of the wearable device can be directly adjusted to the target screen brightness, so that the displayed screen brightness conforms to the brightness of the current environment, avoiding discomfort to the eyes of the user, thereby the accuracy and speed of the screen brightness control can be improved.

[0145] When in the screen-off state, the screen light leakage amount is zero, the current first ambient light intensity can be directly detected, so that the target screen brightness corresponding to the current first ambient light intensity can be determined in advance. In the case where the matching degree between the wrist lifting feature information and the preset feature information reaches the second matching degree, it is indicated that the user's wrist lifting action has been completed or is about to be completed, and then the screen brightness of the wearable device can be adjusted to the target screen brightness, and the screen brightness adjustment is performed before the screen is turned on. The screen brightness seen by the user when the screen is turned on conforms to the brightness of the current environment, avoiding the problem of discomfort to the user's eyes, thereby improving the accuracy and speed of screen brightness control.

[0146] It should be understood that, although Figures 2-4 The steps in the flowchart of the screen brightness control device are displayed in sequence according to the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, the execution of these steps has no strict order limitation, and these steps can be executed in other orders. Moreover, Figures 2-4 At least part of the steps in the screen brightness control device can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed in rotation or alternation with other steps or sub-steps or stages of other steps.
