Abstract

The embodiment of the invention discloses a proximity sensor threshold updating method and device, and a terminal. The method comprises the following steps: when a proximity sensor is detected to be located in a departure state, recording proximity values continuously collected by the proximity sensor and accumulating the continuous collection times; if the continuous collection times reach preset times, updating the threshold of the proximity sensor according to the recorded proximity values; when the proximity sensor is detected to switch from the departure state to a proximity state, resetting the continuous collection times so as to accumulate the continuous collection times and record the proximity values again when the proximity sensor is in the proximity state; and if the re-accumulated continuous collection times reach the preset times, updating the threshold of the proximity sensor based on the re-recorded proximity values. By adoption of the proximity sensor threshold updating method and device disclosed by the embodiment of the invention, the threshold of the proximity sensor can be accurately set, the problem of screen control inaccuracy is solved, and the problem of inaccurate threshold setting caused by the influence of oil contamination to the proximity sensor is avoided.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a method, device and terminal for updating a threshold of a proximity sensor. Background technique [0002] The proximity sensor configured in the terminal is usually an infrared proximity sensor. The infrared proximity sensor includes an infrared emitting tube and an infrared receiving tube. First, the infrared emitting tube emits infrared light outward along the screen direction of the display screen. Then, the infrared light reflected by the blocking object is received by the infrared receiving tube and converted into an electrical signal. The electrical signal is amplified and processed by analog-to-digital conversion (A / D conversion), and the digital signal corresponding to the intensity of the reflected infrared light is obtained and then sent. To the CPU, the CPU takes the digital signal as a close value for further judgment. For example, the distance between ...
