Popis:	We have been developing an image sensor, "FEA-HARP", which consists of a field emitter array (FEA) and high-gain avalanche rushing amorphous photoconductor (HARP). This sensor will be used in an ultrahigh-sensitivity compact HDTV camera. We propose new operation methods for the FEA-HARP that maintain picture quality even when strong light enters the sensor. Experimental results show that blooming generation was suppressed by removing excess charges from the HARP target during horizontal blanking intervals.
