Method and apparatus for adjusting sensing threshold of infrared proximity sensor

An apparatus for adjusting a sensing threshold of an infrared proximity sensor comprising:

• an obtaining module, configured to obtain, through the infrared proximity sensor, a reflected infrared ray intensity value in an environment of a current light intensity;
• a comparison module, configured to compare the reflected infrared ray intensity value, which is obtained by the obtaining module and in the environment of the current light intensity, with a pre-stored reflected infrared ray intensity value, so as to obtain a first difference between the obtained reflected infrared ray intensity value and the pre-stored reflected infrared ray intensity value;
• and
• a modification module, configured to modify the sensing threshold, when the first difference obtained by the comparison module is greater than a preset first threshold;
• wherein the sensing threshold is used to determine whether the infrared proximity sensor is blocked;
• and
• the reflected infrared ray intensity value is a difference between a first infrared ray intensity value and a second infrared ray intensity value, wherein when the infrared proximity sensor does not emit an infrared ray and emits an infrared ray, the first infrared ray intensity value and the second infrared ray intensity value are obtained through measurement by the infrared proximity sensor respectively.
