ABSTRACT:
A form sheet type determining method and apparatus for determining to which of predetermined form sheets an input form sheet corresponds. A plurality of sets of keywords are registered in a keyword register with one set of keywords for each predetermined form sheet type; image data of an input form sheet is read, character strings are extracted from the read image data, and character recognition is performed on each extracted character string; each of the character recognized strings is extracted as a keyword; the extracted keywords are collated, for each form sheet type, with the sets of keywords registered in the keyword register, thereby to determine the type of the input form sheet.
