Abstract

The embodiment of the invention discloses a method for determining the threshold value of a proximity sensor. The method comprises the steps of acquiring a current first signal value of the proximity sensor, selecting a corresponding default scale factor according to the acquired current first signal value, and determining the threshold value of the proximity sensor according to the product of the selected default scale factor and the current first signal value. Correspondingly, the embodiment of the invention further discloses a terminal. According to the method for determining the threshold value of the proximity sensor and the terminal, self-calibration of the threshold value of the proximity sensor can be achieved, and user experience is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and a terminal for determining a threshold value of a proximity sensor. Background technique [0002] When a user uses a touch-screen mobile phone to answer a call, his or her face will often touch the touch screen, and the user may click the on-hook button or the hands-free button unintentionally, thereby causing unnecessary embarrassment. Because the proximity sensor can judge the distance of the object according to the infrared reflection intensity of the reflected light received by the infrared receiving diode, therefore, the proximity sensor is designed into the touch screen mobile phone, and automatically controls the user by comparing the received infrared reflection intensity with the threshold value. Whether the screen is locked or not when receiving a call. At present, the threshold value is a fixed value, which is generally set before leaving the factory....
