Abstract
A plurality of binary images are obtained from one form image by binarizing the form image by using a plurality of binarizing threshold values for improving a recognition rate of the search form irrespective of a state of the inputted form image, and format data are generated respectively from the plurality of binary images. If the inputted form image is a binary image, after the binary image has been converted into a multi-valued image by a vignetting filter, a plurality of binary images are obtained from one form image by executing the binarizing processing by use of the plurality of binarizing threshold values respectively, thereby generating the format data respectively from the plurality of binary images.
