An image processing system capable of checking whether or not an image is correctly read, and of easily correcting an image which is not correctly read is provided. The image processing system includes: an image processing apparatus A which has a reading section 105, an image processing section 110 for performing image processing of a read image, and a metadata generating section 106 for generating metadata for an abnormal image; a storage server B which stores the image and the metadata outputted from the image processing apparatus A; and an image checking apparatus C which checks whether or not the metadata is included in the image acquired from the storage server B, and which when the metadata is included in the acquired image, displays the image on the basis of the metadata, and corrects the acquired image. The image processing system is capable of correcting only the abnormal image, without re-reading all the images.
