Abstract

　センサが出力する光電流を積分した電荷を蓄積する積分容量を有するセンサ部が行及び列からなる２次元アレー状に配置されたイメージセンサにおいて、積分容量の電圧値を走査することで読み出し信号を順次出力する信号読み出し方法は、第１～第３の期間からなる１フレーム期間において、第１の期間では積分容量を用いた１回目の光電流の積分とサンプルホールド容量を用いた１回目のサンプルホールドを行い、第２の期間では積分容量を用いた２回目の光電流の積分を行い、第１及び第２の期間中の処理動作を全センサ部に対して共通、且つ、同時に行い、第３の期間では垂直走査を開始して第１番目から順番に行を選択し、選択された行に対して、読み出し信号が既に出力されている所定行のサンプルホールド容量のリセット、所定行のサンプルホールド容量を用いた２回目のサンプルホールド、選択された行と所定行のサンプルホールド容量の両端電圧の平均化、及び水平走査動作を開始して第１番目の列から順番に列を選択し、選択された列に対して最終出力電圧を順次読み出す。
