1. A projection system, comprising a plurality of projection devices and a control device,
wherein the plurality of projection devices comprises a plurality of processors, a plurality of storage units and a plurality of light valves, the processors comprise a first processor, a second processor, and a third processor, the light valves comprise a first light valve, a second light valve, and a third light valve, each of the processors is connected to different one of the storage units, each of the processors is connected to one of the light valves, and each of the projection devices is configured to provide a first light beam, a second light beam, and a third light beam of different wavelengths,
wherein the control device respectively provides a first signal, a second signal, and a third signal to the plurality of projection devices,
wherein the first processor receives one of the first, second, and third signals, the second processor receives another one of the first, second, and third signals, and the third processor receives the other one of the first, second, and third signals, the first, second, and third processors respectively control the first, second, and third light valves to provide the first, second, and third light beams in turn according to the first, second, and third signals, so as to generate an image beam, and in the same time sequence, the first, second, and third light beams provided by the first, second, and third valves controlled by the first, second, and third processors have different wavelengths,
wherein each of the storage units stores a first information, a second information and a third information, the first information indicates an order of sequentially providing the first light beam, the second light beam and the third light beam, the second information indicates an order of sequentially providing the second light beam, the third light beam and the first light beam, and the third information indicates an order of sequentially providing the third light beam, the first light beam and the second light beam, the first signal corresponds to the first information, the second signal corresponds to the second information, and the third signal corresponds to the third information.
