Abstract
An infrared light detecting device and the infrared detecting method thereof. The device comprises a shield, a first photo detector and a second photo detector. The shield for blocking light is located above the first photo detector and the second photo detector. An opening is disposed on the shield above the first photo detector. In addition, there is a gap arranged between the first photo detector and the second photo detector. The first photo detector can detect the light passing through the opening to generate a photo sensing signal and couple an infrared light signal in the photo sensing signal to the second photo detector in order to output the infrared light signal.
