Abstract: There is provided an image inspection system. An image reading unit reads a formed image which is formed on a recording medium based on original image data to generate read image data. A determination unit compares the read image data and the original image data to determine whether or not the formed image includes a defective region. An extraction unit extracts an image of characters present around the defective region from the read image data. An image display device displays the image of the characters and an image of the defective region such that both the images overlap with each other.

Abstract: An image is read from a recording medium via first and second optical imaging systems disposed such that respective reading regions partially overlap each other in a principal scanning direction on a reading surface. A sum of distances over which first and second images captured by the first and second optical imaging systems, respectively, are displaced in the principal scanning direction with respect to a reference point included in a region in which the reading regions overlap each other is calculated. First and second distances, over which the first and second images are displaced in the principal scanning direction, respectively, are calculated using the sum and first and second reading angles at which the first and second optical imaging systems, respectively, read the reference point. Positions of the first image and the second image in the principal scanning direction are corrected using the first distance and the second distance, respectively.
