1. An image processing device for removing fixed pattern noise in images captured by an image pickup device mounted on a vehicle, comprising: (a) memory on which is stored a plurality of images captured by the image pickup device while the vehicle is running; and (b) a controller operatively coupled to the memory and adapted to generate correction data by extracting high spatial frequency components from portions of the stored images, and to use the correction data to remove fixed pattern noise from images captured by the image pickup device.
