A High-Speed Target Tracking CMOS Image Sensor

The paper proposes a high-speed target tracking CMOS image sensor. The target tracking CMOS image sensor consists of an image sensor array, row-parallel processors, a controller and a SRAM. It implements two novel concise algorithms that composed of efficient operations: such as collision detection, separation detection and position extraction. A 64 times 64 pixel array high-speed target tracking CMOS image sensor chip was implemented in using 0.35 mum 2P4M CMOS process. An N-well/P-sub SAB diode without salicide is used as photodiode in the image sensor. The chip size is 4.5 mm times 2.5 mm. The measured results demonstrated that the chip can perform target tracking at the rate of 1000 fps with more functionality and less area than the reported digital chips. The chip power consumption is 30 mW at the main clock of 20 MHz.
