METHOD FOR IMPROVING THE DYNAMIC RANGE OF AN IMAGING SYSTEM |
摘要 |
<p>Disclosed is a method for improving the dynamic resolution of an imaging system. The method employs a dual sampling or exposure technique which samples light from an image intensifier over a long and a short sample interval. When the resulting measurement for the long sample interval exceeds a threshold level, the short sample interval measurement is used, multiplied by a scaling factor. Below the threshold the long sample interval is used.</p> |
