APPARATUS AND METHOD FOR PROXIMITY SENSING

摘要

According to various embodiments of the present invention, the present invention may include a light output unit that outputs a pre-determined optical signal; a light detection unit that controls a resistance value in accordance with the intensity of illumination by ambient light and detects reflected light when the output optical signal is reflected by an object; and a signal processing unit that receives a reflected light signal which is detected by the light detection unit and calculates the size and phase of the reflected light signal. Also, a variety of other embodiments are possible.
