Problems solved by technology

[0004] It can be seen from the above description that the existing calibration method will directly execute the calibration action after receiving the calibration command. Placement is good, the lamps used for calibration are aging, etc. If these conditions are ignored and calibration is performed directly, large calibration errors may occur, and even calibration errors may occur

Embodiment 1

[0022] Such as figure 1 As shown, the calibration method of the proximity sensor of this embodiment includes the following steps:

[0023] Step 101, receiving a calibration instruction;

[0024] When the proximity sensor in the terminal needs to be calibrated, the operator can operate the terminal to send a calibration instruction, and the terminal receives the calibration instruction sent by the operator.

[0025] The function of the proximity sensor is to detect the distance between the object and the terminal. When the object is detected to be close to the terminal, the terminal is triggered to take corresponding protection actions to avoid misoperation. For example, for a terminal with a touch screen, when using the terminal to make a call, the proximity sensor is used to detect the distance between the face and the terminal, and when the distance between the detected face and the terminal is less than the preset distance, the screen lock action is executed , to prevent ...

Embodiment 2

[0034] The method described in embodiment one, this embodiment will be described further, as figure 2 As shown, the method of the present embodiment includes the following steps:

[0035] Step 201, receiving a calibration instruction;

[0036] Step 202, detecting the tilt angle of the terminal;

[0037] In a specific implementation, a gravity sensor (G-sensor) may be used to detect the tilt angle of the terminal.

[0038] Step 203, judging whether the tilt angle of the terminal is greater than a preset angle threshold, if greater, then perform step 207, otherwise perform step 204;

[0039] The preset angle threshold can be set according to actual conditions, for example, 5 degrees, 10 degrees, etc., which are not specifically limited here. If the tilt angle of the terminal is greater than the preset angle threshold, it means that the base of the terminal is not in a horizontal position, and the tilt angle is too large. In this scenario, if the proximity sensor is calibrate...

Embodiment 3

[0052] In order to better implement the above method, the present invention also provides a terminal, such as image 3 As shown, the terminal of this embodiment includes:

[0053]a receiving unit 301, configured to receive a calibration instruction;

Abstract

The embodiment of the invention discloses a proximity sensor calibration method and a terminal. The proximity sensor calibration method comprises steps: a calibration instruction is received; whether to meet a preset calibration condition is detected; and if not, the calibration instruction is denied to be executed, and if yes, the calibration instruction is executed to calibrate the proximity sensor in the terminal. The embodiment of the invention has the advantages that calibration errors can be reduced, and the calibration reliability can be ensured.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a calibration method and a terminal for a proximity sensor. Background technique [0002] The proximity sensor is an important electronic device in the terminal. After the proximity sensor is installed, the proximity value will be inconsistent due to differences in the patch and structure. In order to reduce the difference of devices and enhance the consistency of the terminal, it is necessary to calibrate the proximity sensor in the terminal. [0003] The specific calibration method includes: after receiving the calibration instruction, adjust the proximity value of all proximity sensors to a preset value, such as 200, calculate the offset value (offset) of each proximity sensor, and set the offset value of each sensor to Stored in the non-volatile storage system of the corresponding terminal, the terminal will load the corresponding offset va...
