摘要：
An interactive input system comprises at least one imaging device capturing images of a region of interest, a plurality of radiation sources, each providing illumination to the region of interest and a controller coordinating the operation of the radiation sources and the at least one imaging device to allow separate image frames based on contributions from different radiation sources to be generated.
