Abstract

Wide-angle cameras are widely used in surveillance and medical imaging applications nowadays. Images captured by wide-angle lens suffer from barrel distortion which means that the outer regions of the image are compressed more than the inner one. A low-cost high-speed VLSI implementation for barrel distortion correction is presented in this brief. In our simulation, the proposed circuit can achieve 200 MHz with 45 K gate counts by using TSMC 0.18 μ technology. Compared with the previous distortion correction design, our circuit requires less hardware cost and achieves faster working speed.
