In an imaging system that generates a stereoscopic image using two types of captured images having parallax, the parallax value between the left image signal and the right image signal, which are two image signals having parallax, is adjusted to be substantially zero The parallax adjusting unit 61, the comparing unit 62 for comparing the luminance values of the left image signal and the right image signal whose parallax has been substantially adjusted to zero by the parallax adjusting unit 61, and the information compared by the comparing unit 62 A white-scratch detection unit 63 that detects a white-scratch on the image pickup device 25 based on the detection result, a white-scratch correction unit 64 that performs predetermined correction on a pixel in which the white-scratch is generated based on a detection result in the white-scratch detection unit 63, Have視差を有する２種類の撮像画像を用いた立体画像を生成する撮像システムにおいて、視差を有する２つの画像信号である左側画像信号と右側画像信号との視差の値を実質的にゼロとなるよう調整する視差調整部６１と、視差調整部６１において実質的に視差がゼロに調整された左側画像信号と右側画像信号との輝度値を比較する比較部６２と、比較部６２において比較された情報に基づいて撮像素子２５上の白傷を検出する白傷検出部６３と、白傷検出部６３における検出結果に基づいて当該白傷が生じた画素に所定の補正を施す白傷補正部６４と、を有する。
