Method and apparatus for terminal to determine approach of object

A non-transitory computer readable medium including computer-executable instructions for execution on a terminal, which is configured to determine whether an object is approaching, such that when the computer-executable instructions are executed by the terminal a method is carried out comprising:

• reading a first infrared intensity value when an infrared emitting diode is off and reading a second infrared intensity value when the infrared emitting diode is on;
• obtaining a first difference value between the second infrared intensity value and the first infrared intensity value as an intensity value of a reflected infrared ray;
• determining whether a second difference value between the intensity value of a reflected infrared ray and an infrared intensity threshold that is stored by the terminal itself is greater than a preset second threshold;
• and
• determining when the second difference value is greater than the preset second threshold, that there is an object approaching the terminal;
• wherein the stored infrared intensity threshold is the first difference value between the second infrared intensity value and the first infrared intensity value and is obtained during initial activation.

A non-transitory computer readable medium including computer-executable instructions for execution on a terminal, which is configured to determine whether an object is approaching, such that when the computer-executable instructions are executed by the terminal a method is carried out comprising:

• reading when an infrared emitting diode of the terminal is activated an intensity value of a received infrared ray;
• caching the intensity value of the received infrared ray;
• reading when an additional infrared ray is received from the outside an intensity value of the additional infrared ray;
• calculating a difference value between the intensity value of the additional infrared ray and the cached intensity value;
• and
• determining, when the calculated difference value is greater than a preset threshold, that an object is approaching the terminal;
• wherein the stored infrared intensity threshold is the first difference value between the second infrared intensity value and the first infrared intensity value and is obtained during initial activation.
