In the past years the use of CMOS sensors instead of CCDs has enabled the development of high-speed video cameras offering digital outputs readout flexibility and lower manufacturing costs. In this paper we propose a high-speed smart camera based on a CMOS sensor with embedded processing. Two types of algorithms have been implemented. A compression algorithm specific to high-speed imaging constraints has been implemented. This implementation allows to reduce the large data flow 6.55 Gbps and to propose a transfer on a serial output link USB 2.0 . The second type of algorithm is dedicated to feature extraction such as edge detection markers extraction or image analysis wavelet analysis and object tracking. These image processing algorithms have been implemented into an FPGA embedded inside the camera. These implementations are low-cost in terms of hardware resources. This FPGA technology allows us to process in real time 500 images per second with a 1280 X 1024 resolution. This camera system is a reconfigurable platform other image processing algorithms can be implemented. Copyright 2007 R. Mosqueron et al.
