Taking the example that the image acquisition component included in the mobile terminal is the telescopic camera, as the service time of the telescopic camera goes forward, the hardware of the telescopic camera and the driving component for driving the telescopic camera to move may be aged and slightly damaged, which may cause the function degradation of the hardware of the telescopic camera and the driving component, for example, the telescopic camera may not move in place, if the hardware of the telescopic camera and the driving component are not completely damaged, and the user directly holds the mobile terminal to a specific maintenance point for maintenance, a large amount of time and money may be spent by the user, and professional technicians at the maintenance point also need to perform a plurality of tests on the mobile terminal, which not only improves the repair rate of the mobile terminal, but also increases the after-sale cost of manufacturers.
The embodiment of the disclosure provides a position detection method for an image acquisition assembly, when a first detection configuration is used for detecting that the image acquisition assembly has abnormal movement within a stroke range, a detection calibration mechanism is started, self calibration can be performed through the calibration mechanism, test maintenance can be avoided from going to and fro a maintenance point under an unnecessary condition, so that the repair rate is reduced, the maintenance cost of a user and a manufacturer is reduced, and the user experience is improved.
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the present disclosure provides a method for detecting a position of an image capturing assembly, fig. 1 is a schematic flow chart of a method for detecting a position of an image capturing assembly according to an exemplary embodiment, and as shown in fig. 1, the method mainly includes the following steps:
in step 101, when the image acquisition assembly is detected to have abnormal movement within a stroke range, starting a detection operation for calibrating the image acquisition assembly; wherein, the image acquisition assembly can move under the drive of drive assembly.
Here, the movement abnormality may be that the image capturing assembly has failed to move or cannot move to a set position. The detection operation can be an operation started by a user according to a requirement or an operation automatically started by the mobile terminal when the mobile terminal detects that the image acquisition assembly has abnormal movement within a stroke range.
In the embodiment of the disclosure, when the mobile terminal detects that the image acquisition assembly has abnormal movement within the stroke range, the mobile terminal or an application program installed on the mobile terminal can output prompt information to prompt a user to start detection operation. For example, a prompt box may be output by the application program, and prompt information may be displayed in the prompt box, so as to prompt the user to start the detection operation according to the set steps through the prompt information.
In another embodiment, the user may also initiate the detection operation autonomously. For example, a control capable of starting detection operation is arranged on a corresponding interface of the mobile terminal, when a user needs to use the mobile terminal, the user can enter the corresponding interface to find the control, and the detection operation is started based on the control.
In step 102, the image acquisition assembly is driven to move, and whether the movement displacement of the image acquisition assembly is within a normal range or not is detected.

And if the first position is the original position of the image acquisition assembly in the terminal, the second position is the position moved out by the image acquisition assembly according to the received instruction. The housing of the mobile terminal is provided with an opening through which the image acquisition assembly can move between a first position and a second position. When the image acquisition assembly is located at the first position, the top of the image acquisition assembly can be flush with the shell of the mobile terminal, namely the top of the image acquisition assembly can form a part of one outer surface of the image acquisition assembly; so, on the one hand for when the image acquisition subassembly is located mobile terminal's casing, mobile terminal's surface wholeness is better, and on the other hand, the reduction is because harm such as dust that the opening was opened the introduction.

If the position corresponding to the position sensing parameter is determined to be 2 mm from the preset list, the movement displacement of the image acquisition assembly is determined to be within a normal range, otherwise, the movement displacement of the image acquisition assembly is not within the normal range.
In step 103, if the movement displacement is not within the normal range, the image capturing assembly is calibrated based on the detection operation.
