Abstract
An image processing system includes an image reader that reads a document image and that generates image information regarding a CIELAB color space, and a processor configured to: obtain an a*b*-plane two-dimensional histogram for the image information; obtain a background color of the document image using the a*b*-plane two-dimensional histogram and count a number of black spots of the image information for each of bins of the a*b*-plane two-dimensional histogram; subtract the number of black spots in a bin determined to include the background color from a total number of black spots in all the bins; and determine, if an obtained value is larger than a predetermined threshold, that the document image indicates a non-blank sheet.
