Real-Time Algorithm Enabling High Dynamic Range Imaging and High Frame Rate Exploitation for Custom CMOS Image Sensor System Implemented by FPGA with Co-Processor

摘要

We present results from a prototype CMOS camera system implementing a multiple sampled pixel level algorithm ("Last Sample Before Saturation") in real-time to create High-Dynamic Range (HDR) images that approach the dynamic range of CCDs. The system is built around a commercial 1280×1024 CMOS image sensor with 10-bits per pixel and up to 500 Hz full frame rate with higher frame rates available through windowing. We provide details of system architecture and present images collected with the system.
