Abstract
The present invention provides a proximity sensing device, which comprises an ambient light calibration digital-to-analog converter and at least one crosstalk calibration digital-to-analog converters. The proximity sensing device is able to quickly generate calibration parameters for the interference caused by the ambient list and crosstalk caused by different reflection, to calibrate the sensed signals to avoid wrong judgments.
