PROBLEM TO BE SOLVED: To provide a method for automatically extracting characteristics of each scanner provided on a document processing system, and a method for preparing and using a single document definition database even when scanning environments at defining a document and at reading a document are different from each other or a plurality of scanners are used for defining or reading the document, thereby facilitating a document definition preparation operation and preventing degradation in accuracy of a document reading. SOLUTION: The document reading system scans a profile preparation sheet under each scanning environment, and extracts scanning characteristics by analyzing a read image. The document reading system then records a profile of the scanning environment defining the characteristic or link information to the characteristic in each document definition, compares the profiles for definition preparation and for the book reading apparatus while reading the document, and recognizes and verifies a character string based on the comparison result.
