Abstract
An image sensor for 3-D range map acquisition with pixel-parallel correlation in the region of interest is presented. By the use of modulated sheet light projection and correlation technique, the sensor can suppress background illumination. In order to achieve high resolution, correlation circuits is put outside of 128 _ 128 pixel array, one in each column and 16 in each row. The sensor finds the columns which includes activated pixels by column-parallel correlation circuit and next searches the illuminated position within the region by the row-parallel correlation circuit block. The correlation circuit achieves -18 dB signal-to-background ratio (SBR) and 76 dB dynamic range in simulation. The frame rate is estimated to be 200 - 500 fps.
