A CMOS image sensor that can operate in both linear and logarithmic mode is described. Two sets of data are acquired and combined in the readout path to render a high dynamic range image. This is accomplished in real-time without the use of frame memory. A dynamic range in excess of 120 dB was achieved at 26 frames/s (352times288-array). The system addresses the problems of high fixed pattern noise (FPN), slow response time, and low signal-to-noise ratio (SNR) in logarithmic mode. FPN has been… CONTINUE READING
