Projection system and control method of the same

A control method of a projection system, that comprises a display part, a digital light processor (DLP) optical system, a system storage part to store data inherent information corresponding to optical system data of the DLP optical system and a DLP storage part to store the optical system data and data inherent information corresponding to the optical system data, the control method of the projection system comprising:

• receiving a control signal to download the optical system data from the DLP storage part to the system storage part;
• reading out each of the data inherent information from the DLP storage part and the system storage part;
• determining whether the data inherent information of the system storage part and the DLP storage part corresponds with each other;
• and
• downloading the optical system data if the data inherent information of the system storage part and the DLP storage part corresponds with each other.
