Abstract

Embodiments of the present application relate to a method for detecting interference of an infrared signal and a projection device, the method comprising: determining first time information; determining second time information; determining, based on the first time information and the second time information, whether the second infrared signal received by the receiver is currently interfered by the infrared signal emitted by the second emitter. Thus, whether the infrared signal is currently interfered can be detected based on the time associated with the infrared signal conforming to the preset signal protocol and the time associated with the infrared signal not conforming to the preset signal protocol, and whether the infrared function of the device is currently interfered by the infrared signal can be detected.
