PROBLEM TO BE SOLVED: To perform projection on a plurality of screens using a simple structure.SOLUTION: A projection system 1 includes a projection device 10 and an optical path switchover device 50. The projection device 10 includes: projection systems (11-16) for projecting images; and a CPU (20) for causing a synchronous signal output unit (communication unit) SO to output a synchronous signal for switching the projection of images by the projection systems in a time division manner. The optical path switchover device 50 includes a light control structure for outputting incident light to a first direction or a second direction different from the first direction, to cause the light control structure to output light by switching the incident light to the first direction or the second direction, on the basis of the synchronous signal from the projection device 10. |
