1. A mobile device, comprising:
an infrared emitter, configured to emit an infrared ray by using first power in a first mode or emit the infrared ray by using second power in a second mode, wherein the first power and the second power are different; a proximity sensor, configured to detect a reflected light of the infrared ray and determine whether an object is in close proximity to the mobile device based on the reflected light; a communication unit, configured to conduct an incoming call; a touch panel, configured to detect a touch operation on the mobile device; a processor, coupled to the infrared emitter, the proximity sensor, the communication unit and the touch panel, and configured to enable the infrared emitter and control the infrared emitter to enter the second mode after the communication unit conducts the incoming call, disable the touch panel when the proximity sensor determines that the object is in close proximity to the mobile device, and enable the touch panel when the proximity sensor determines that no object is in close proximity to the mobile device. |
