摘要： A proximity sensor, a control method thereof and an electronic apparatus equipped with the proximity sensor are disclosed. The proximity sensor connected to a light-emitting module includes a light source, a light receiver and a control module. The light source emits lights at predetermined time intervals. The light receiver receives reflected lights of the emitted lights that are reflected from an object. The control module determines whether an average value of intensity values of the reflected lights is larger than a threshold value. If yes, the control module further determines whether a difference between a highest and a lowest intensity value of the reflected lights falls in a preset range. If yes, the control module would control the light-emitting module to change to a different light mode thereof. When a user reacts to the different light mode, the system will be able to tell whether a real user is present.

摘要： The ambient light sensor structure includes a power supply, a converter, and a pulse processing unit. The power supply provides a reference voltage interface, a high voltage interface and a low voltage interface. The converter includes a first current-to-pulse converter, a second current-to-pulse converter, a first light sensor and a second light sensor. The pulse processing unit comprises a signal subtraction component for circuit blocking, a counter, a digital-to-analog converter and a buffer by series connection. Without incident light, two light sensors would produce a dark current due to the material characteristics of the two photo diodes. Therefore, two current to pulse converters convert the dark current into a pulse signal and transmit the pulse signal to the signal subtraction component in order to cancel the dark current. By the method mentioned above, the dark current caused by the material characteristic of the two light sensors can be eliminated.
