Abstract (in Japanese) (See Japanese page) 
(in English) A vision sensor with multiple spatial band-pass filtering has been developed. The vision sensor is comprised of an active pixel sensor (APS), sample and hold (S&H) circuits, an analog resistive network, and a field-programmable gate array (FPGA). The resistive network realizes instantaneous spatial filtering whose spatial property depends on its resistance. We have implemented a digital circuit in FPGA, which controls resistance of the resistive network and the timing of reading out of spatial filtered images within a frame. The sensor outputs three spatial band-pass filtered images at 50 frames per second.
