Abstract :
We have developed a Profile Imager aimed at high-speed automatic target tracking. The Profile Imager can perform both target tracking within a 512 × 512-pixel entire image area and acquisition of partial images simultaneously and independently. Experimental results of capturing 128 × 128-pixel partial images of an automobile license plate at 1620 frames/s are presented. In addition, results of integrating 89 partial images demonstrate the capability of the device as a high-speed, high-resolution, high-dynamic-range image tracker. A 0.6-μm two-poly three-metal CMOS process is used to implement a 13.0 mm × 14.3 mm imager.
