Assignee: HONOR DEVICE CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 15:
16. The method of claim 11, wherein:
the trigger operation comprises a trigger operation for turning off the camera;
the first reference signal further comprises a first retracting reference signal, and the second reference signal further comprises a second retracting reference signal;
the preset threshold further comprises a second preset threshold;
the first retracting reference signal and the second retracting reference signal are induction signals generated by the first working surface and the second working surface of the Hall sensor, respectively, in response to the camera being in the retracting position;
the controlling, in response to a trigger operation being received, the driving assembly to drive the bracket to move in a preset direction comprises: in response to a trigger operation for turning off the camera being received, controlling the driving assembly to drive the bracket to move in the second direction;
the calculating the first difference between the first induction signal and a first reference signal, and calculating the second difference between the second induction signal and a second reference signal further comprises: calculating the first difference between the first induction signal and the first retracting reference signal, and calculating the second difference between the second induction signal and the second retracting reference signal;
the determining whether an absolute value of the second difference is less than a preset threshold further comprises: determining whether the absolute value of the second difference is less than the second preset threshold; and
the determining that the camera is in the stretching-out position or in the retracting position in response to the absolute value of the second difference being less than the preset threshold further comprises: in response to the absolute value of the second difference being less than the second preset threshold, determining that the camera is in the retracting position.
