Environmental compensation method in proximity sensor and proximity sensor having improved environmental compensation performance

A proximity sensor having improved environmental compensation performance, comprising:

• a processor;
• and
• a non-temporary memory storing a command,
• wherein, when operated by the processor, the command cause the processor to be configured to:
• sense, by a first sensor, a first sensing value;
• sense, by a second sensor, a second sensing value;
• preprocess the second sensing value;
• sense, by a third sensor, a third sensing value;
• preprocess the third sensing value;
• compensate for the first sensing value by adding or subtracting the preprocessed second sensing value with respect to the first sensing value;
• and
• re-compensate for the first sensing value by adding or subtracting the preprocessed third sensing value with respect to the compensated first sensing value.

An environmental compensation method in a proximity sensor, the method comprising:

• sensing, by a first sensor, a first sensing value;
• sensing, by at least one second sensor, at least one second sensing value;
• and
• compensating for the first sensing value by adding or subtracting the preprocessed second sensing value with respect to the first sensing value,
• wherein sensing the second sensing value comprises:
• adjusting at least one sensor feature selected from among a sensing time, a sensing cycle, and a gain of the second sensor using at least one setting value for compensation for environmental variation before sensing by the second sensor.
