An 80 × 60 pixels arbitrated address-event imager has been designed and fabricated in a 0.6 µm CMOS process. The output bandwidth is allocated according to the pixel's demand. The imager has a large dynamic range: 200 dB (pixel) and 120 dB (array). The power consumption is 3.4 mW in uniform indoor light. The imager is capable of 8.3K effective frames per second.
