| Abstract: | Demands for the feature of high dynamic range of digital camera were seen in lots of applications of machine vision.Logarithmic image sensor supplies the hardware architecture to the requirement,but the exposure algorithm was still manual and ineffective.A high dynamic range auto-exposure algorithm based on Logarithmic image sensor was presented to meet the requirement.With field-programmable gate array,this algorithm can separate the natural scenes into region of interest and region of target.Real-time aut... |
