PROBLEM TO BE SOLVED: To provide a method of driving an imaging apparatus, the imaging apparatus, and an imaging system, capable of reducing a noise component included in a signal to be outputted by an image pixel.SOLUTION: A signal SEL(N-1) of N-1th line scanned before an image pixel of Nth line becomes a high level, and a signal RES(N) of Nth line is shifted from the high level to a low level in a period of reading out an image pixel of N-1th line. A reset transistor connected to a floating diffusion part of the image pixel of Nth line without performing the reading from the pixel of the image signal is turned off. At a time t3, a signal SEL (N) of Nth line becomes the high level, and a reset signal RES (N) becomes the high level.SELECTED DRAWING: Figure 4 【課題】画素が出力する信号に含まれるノイズ成分を低減する撮像装置の駆動方法、撮像装置、撮像システムを提供する。【解決手段】Ｎ行目の画素の前に走査されるＮ−１行目の信号ＳＥＬ（Ｎ−１）がハイレベルとなり、Ｎ−１行目の画素信号を読み出す期間に、Ｎ行目の信号ＲＥＳ（Ｎ）がハイレベルからローレベルに遷移し、画素信号の画素からの読み出しを行っていないＮ行目の画素の浮遊拡散部に接続されたリセットトランジスタをオフにする。時刻ｔ３に、Ｎ行目の信号ＳＥＬ（Ｎ）がハイレベルとなるとともに、リセット信号ＲＥＳ（Ｎ）がハイレベルとなる。【選択図】図４
