mainly in the entertainment segment, with products based on pattern-projection techniques. Although this technology has shown remarkable performance in terms of cost, measurement accuracy and power consumption, there is also an increasing interest towards alternative techniques, such as stereo vision and Time-of-Flight (ToF), in order to further improve the range camera characteristics. After a decade from the demonstration of the first ToF range imagers with reasonably good performance results [1], this technology has started to attract the attention of large companies, because of the potential consumer applications in security, gaming and ambient assisted living. While the earliest prototypes of ToF range cameras were based on dedicated CMOS/CCD technologies, the search for higher resolutions and lower costs have
