Remote sensing system and electronic apparatus having same

An electronic apparatus, comprising:

• a remote control unit comprising a housing and a two light sources installed in/on the housing, the two light sources comprising:
• a first light source for emitting infrared light of a first central wavelength;
• a second light source for emitting infrared light of a second central wavelength;
• two image capturing devices for capturing images of the first and second light sources, the image capturing devices each comprising an infrared sensitive image sensor and an infrared pass filter having two passbands for respectively allowing the infrared light of the first and second central wavelengths to pass therethrough;
• a processing unit for analyzing the images captured by the image capturing devices thereby determining positions of the light sources relative to the image capturing devices.
