自动校准方法及电子装置;AUTOMATIC CALIBRATION METHOD AND ELECTRONIC APPARATUS

摘要

一种自动校准方法，其适用于包含距离感应器的电子装置。自动校准方法包含下列步骤：当特定功能启动时，重置最小值指标以及最大值指标的资料；根据距离感应器之读数更新最小值指标以及最大值指标；当距离感应器根据距离感应器的至少一门槛值侦测到远离事件时，重置最小值指标；当距离感应器根据距离感应器的门槛值侦测到接近事件时，重置该最大值指标；以及，每当最小值指标或最大值指标更新时，根据最小值指标或最大值指标重新计算门槛值。; updating the minimal index and the maximal index according to readings from the proximity sensor; resetting the minimal index when the proximity sensor detects a far event according to a threshold value of the proximity sensor; resetting the maximal index when the proximity sensor detects a near event according to the threshold value; and, re-calculating the threshold value according to the minimal index or the maximal index every time the minimal index or the maximal index is updated.
