Abstract
A projection system and control method thereof are provided. A player apparatus generates and transmits an image signal to a projection apparatus, and a plurality of first distance values within a first time are received through a distance sensor. An average value of the plurality of first distance values is calculated and set as a reference value. During a playback of the image signal, an average value of a plurality of second distance values received from the distance sensor is calculated every second time to serve as a first-stage detection value. When the first-stage detection value is less than the reference value, the image signal is paused.
