A projection system has a display part and a digital light processor (DLP) optical system, the projection system including: a system storage part to store data inherent information corresponding to optical system data of the DLP optical system; a DLP storage part to store the optical system data and the data inherent information corresponding to the optical system data; and a controller to determine whether the data inherent information of the system storage part and the DLP storage part corresponds with each other, after reading out each of the data inherent information from the DLP storage part and the system storage part, in case that the optical system data are downloaded from the DLP storage part to the system storage part, and to download the optical system data if the data inherent information corresponds with each other.
