Abstract
【解決手段】 固体撮像装置1は、(1) M×N個の画素がM行N列に2次元配列され、第m行第n列にある画素Pm,nがフォトダイオードPD1m,nを含む光検出部11と、(2) 光検出部11のM行のうちから1以上の行を選択して、その選択した行にある各画素に対し光入射に応じてフォトダイオードPD1m,nで発生した電荷の蓄積を指示するとともに、光検出部11の行毎に各画素の電荷蓄積量に応じたデータの出力を指示する行選択部20と、(3) 行選択部20からの指示により光検出部11の行毎に出力された各画素のデータを入力して、画素毎にデータを出力する第1信号処理部30と、を備える。
【選択図】 図1
Description
先ず、本発明に係る固体撮像装置の第1実施形態について説明する。図1は、第1実施形態に係る固体撮像装置1の構成図である。この図に示される固体撮像装置1は、光検出部11、行選択部20および第1信号処理部30を備える。
次に、本発明に係る固体撮像装置の第2実施形態について説明する。図7は、第2実施形態に係る固体撮像装置2の構成図である。この図に示される固体撮像装置2は、光検出部12、行選択部20、第1信号処理部30、第2信号処理部40および第3信号処理部50を備える。この第2実施形態における行選択部20および第1信号処理部30それぞれは、前の第1実施形態における行選択部20および第1信号処理部30と同様のものである。第1実施形態に係る固体撮像装置1と比較すると、この第2実施形態に係る固体撮像装置2は、光検出部12に含まれる各画素Pm,nの構成の点で相違し、また、第2信号処理部40および第3信号処理部50を更に備える点で相違する。
本発明は、上記実施形態に限定されるものではなく、種々の変形が可能である。例えば、光検出部の各画素Pm,nは、上記実施形態ではAPS構造のものであったが、PPS(PassivePixel Sensor)構造のものであってもよい。
