摘要：
The image projection system is capable of freely adjusting a tone to suit user preferences. The system has a synchronization signal generating device that generates a synchronization signal composed of a plurality of on-off patterns in synchronism with rotation of a color filter and outputs each of predetermined power levels corresponding one-to-one with the on-off patterns to the high-pressure discharge lamp at fixed timing.
