We have developed a 1/3.2-inch 1.27Mpixel 500fps (0.31Mpixel 1000fps 2×2 binning) vision chip with 3D-stacked CMOS image sensor. This sensor achieves high resolution and high sensitivity by back-illuminated stacked pixels. In addition, the sensor achieves high speed operation “each pixels” and “each frames” by two kinds of column-parallel processing units. With this technology, it is possible to provide “Visual Feed Back” to the control device with an accuracy that cannot be identified (in units of 1ms) by human eyes.
