Claim Text:
1. A projection system comprising: a light source device for generating an output light which is a repeating color sequence of at least two primary color lights, the light source device including: a synchronization signal generator for generating a synchronization signal representing a timing of the color sequence of the output light; projecting optics for projecting the output light onto a screen; a detector for measuring color properties of the output light; and a controller for calculating drive current values corresponding to each of the at least two primary colors based on a target white balance and the measured color properties of the output light, and supplying a modulated drive current to the light source device, the modulated drive current being synchronized to the synchronization signal and having the calculated drive current values, wherein the output light of the light source has the target white balance.
