    • A detection error of foreign substance due to the presence of a newly generated defective pixel can be considerably prevented. An image pickup apparatus includes a foreign substance detector detecting foreign substance adhering to an optical member arranged on a light axis for image capturing in accordance with an image signal obtained by the image pickup device, a defective pixel position detector detecting a position of a defective pixel in the image pickup device in accordance with an image signal obtained by the image pickup device, a storage unit storing position information detected by the defective pixel position detector, and a controller controlling processing so that the foreign substance detector detects the foreign substance after the defective pixel position detector detects the position of the defective pixel.
    • 可以显着地防止由于新产生的缺陷像素的存在引起的异物的检测误差。 图像拾取装置包括:异物检测器,根据由图像拾取装置获得的图像信号检测粘附到光轴上的用于图像拍摄的光学构件的异物;缺陷像素位置检测器,检测缺陷像素的位置 在图像拾取装置中,根据由图像拾取装置获得的图像信号,存储单元存储由缺陷像素位置检测器检测到的位置信息,以及控制器控制处理,使得异物检测器在缺陷后检测异物 像素位置检测器检测缺陷像素的位置。
