Abstract:
An image pickup apparatus comprising:(a) image pickup means for forming an image signal that includes a bit image signal and a subsequent bit noise signal alternately bit by bit; and(b) one-chip process means including:(b-1) first and second sample-hold means for respectively and alternately separating the bit image signal and the bit noise signal from said image signal bit by bit;(b-2) first amplifier means for receiving the bit image signal and amplifying the received bit image signal and second amplifier means for receiving the subsequent bit noise signal and amplifying the received bit noise signal; and(b-3) A-D converting means for receiving the bit image signal amplified by said first amplifier means and the subsequent bit noise signal separately amplified by said second amplifier means, said A-D converting means forming a digital image signal from the received bit image signal and subsequent bit noise signal.
