Autocalibration of the A/D converter within the CMOS type image sensor

摘要: A method for initializing a counter within corresponding set of A/D converters N sets single-chip CMOS-type image sensor in order to minimize none uniformity across the is provided. The single chip CMOS type includes an sense array having columns output lines outputting analog signals respectively; and signal process device generating digital each which corresponds one respectively. has input converter including comprises steps applying predetermined reference voltage at such that compensation value obtained. further preloads with converter.
