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

Claim 13:
14. The method of claim 11, wherein:
the trigger operation input comprises a trigger operation for starting the camera;
the first reference signal comprises a first stretching-out reference signal, and the second reference signal comprises a second stretching-out reference signal;
the preset threshold comprises a first preset threshold;
the first stretching-out reference signal and the second stretching-out 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 stretching-out position;
the controlling, in response to the trigger operation being received, the driving assembly to drive the bracket to move in a preset direction comprises: in response to the trigger operation input for starting the camera being received, controlling the driving assembly to drive the bracket to move in the first 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 comprises: respectively calculating the first difference between the first induction signal and the first stretching-out reference signal, and the second difference between the second induction signal and the second stretching-out reference signal;
the determining whether an absolute value of the first difference is less than a preset threshold comprises: determining whether the absolute value of the first difference is less than the first 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 first difference being less than the preset threshold comprises: in response to the absolute value of the first difference being less than the first preset threshold, determining that the camera is in the stretching-out position.
