A locally autoadaptive image sensor LARS II (Lokal-AutoadaptiveR Sensor) with 386/spl times/256 pixels was designed and fabricated in TFA (thin film on ASIC) technology. Every pixel contains an automatic shutter, made of 17 transistors and two capacitors on an area of 40 /spl mu/m/spl times/38.3 /spl mu/m, that adapts the integration time to the local intensity. This allows the capture and processing of scenes with extremely high dynamic range. Sample images and measurements shown in this paper verify the total dynamic range of 120 dB.
