INTERACTIVE INPUT SYSTEM WITH CONTROLLED LIGHTING.

摘要

An interactive input system (20) comprises at least one imaging device (60, 62) capturing images of a region of interest, a plurality of radiation sources (40 to 44, 64, 66), 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.
