PROBLEM TO BE SOLVED: To shorten the operation time for correcting RTS noise and threshold defect noise.SOLUTION: An imaging device includes a pixel part having a plurality of pixels, each outputting a plurality of pixel signals by repeating reset and signal output a predetermined number of times, a threshold storage section storing a RTS threshold for detecting RTS noise, and a data processing section for comparing each of the plurality of pixel signals with the RTS threshold, for each pixel, determining whether or not each pixel signal is RTS noise, and based on the rest of pixel signals after removing the pixel signals determined as the RTS noise, generating the RTS exclusion pixel value of each pixel.SELECTED DRAWING: Figure 7 【課題】ＲＴＳノイズおよび閾値欠陥ノイズ補正の演算時間を短縮する。【解決手段】複数の画素を有し、それぞれの画素がリセットと信号出力とを予め定められた回数繰り返して複数の画素信号を出力する画素部と、ＲＴＳノイズを検出するＲＴＳ閾値を記憶する閾値記憶部と、それぞれの画素について、複数の画素信号のそれぞれと、ＲＴＳ閾値とを比較して、それぞれの画素信号がＲＴＳノイズか否かを判定し、ＲＴＳノイズと判定された画素信号を除外した残りの画素信号に基づいて、それぞれの画素のＲＴＳ除外画素値を生成するデータ処理部とを備える撮像装置を提供する。【選択図】図７
