Paper Abstract

We present results from a prototype CMOS camera system implementing a multiple sampled pixel level algorithm (“Last Sample Before Saturation”) 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 analyze imagery data collected at room temperature for SNR versus photocurrent, among other figures of merit. Results conform to expectations of a model that uses only dark current, read noise, and photocurrent as input parameters.
