Abstract: A proximity sensing device includes a proximity sensor including a light source, a light detector including a first photodiode adapted to generate a first signal, and a second photodiode adapted to generate a second signal, the second photodiode and the light source being separated from the first photodiode with a separator. The proximity sensing device further includes a selecting circuit adapted to compare the first signal to the second signal, and to select a signal from the first and second signals according to the executed comparison.
