Ultra High Speed 3-D Smart CMOS Imager Sensor

In these days, a high-speed and high-resolution 3-D imaging system has a wide wide variety of applications including gesture recognition, depth-key object extraction, and computer vision. Moreover, ultra-high-speed range finding provides the possibility of additional applications such as shape measurement, observation of high-speed moving objects, and fast visual feedback systems in robot vision. Therefore, we have presented a concept of a row-parallel search architecture on the focal plane and demonstrated the possibility of 1000 range maps/s range finding with practical pixel resolution. At now, we research higher scan architecture than row-parallel search.
