and 202, responding to the wrist lifting operation, and acquiring the wrist lifting characteristic information corresponding to the wrist lifting operation.

The wrist raising operation is an operation of raising the wrist or ankle of the user upward. The wrist-lifting characteristic information refers to characteristic information collected during the process that the wrist or the ankle of the user is lifted upwards, and for example, the characteristic information comprises at least one of a wrist-lifting amplitude, a wrist-lifting direction and a rotation angle.

Specifically, the user wears the wearable device on the wrist, and when the user uses the wearable device while lifting the wrist, the wearable device can detect whether the user has a wrist-lifting operation.

determining the current screen state of the wearable device under the condition that the matching degree between the wrist lifting feature information and the preset feature information reaches the first matching degree;

when the current screen state of the wearable device is a bright screen state, acquiring the screen light leakage amount of the wearable device and second ambient light intensity in the bright screen state;

and determining the current first ambient light intensity based on the second ambient light intensity in the bright screen state and the screen light leakage amount.

7. The method of claim 6, wherein the obtaining the screen leakage amount of the wearable device when the current screen state of the wearable device is a bright screen state comprises:

when the current screen state of the wearable device is a bright screen state, determining a current screen picture displayed by the wearable device and current screen brightness corresponding to the current screen picture;

and acquiring the screen light leakage amount corresponding to the combination containing the current screen picture and the current screen brightness based on the mapping relation between the combination containing the screen picture and the screen brightness and the screen light leakage amount.

8. The method according to any one of claims 1 to 7, wherein before the acquiring, in response to a wrist raising operation, wrist raising feature information corresponding to the wrist raising operation, further comprises:

acquiring acceleration information and angular velocity information of the wearable device;

and under the condition that the acceleration information and the angular velocity information meet the preset wrist lifting condition, judging that the wrist lifting process is in progress.

9. A screen brightness control device applied to wearable equipment is characterized by comprising:

10. A wearable device comprising a memory and a processor, the memory having stored therein a computer program that, when executed by the processor, causes the processor to perform the method of any of claims 1-8.

11. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the method according to any one of claims 1 to 8.
