ABSTRACT:
When texts recognized by an OCR are registered and those texts are searched by a search word, a state in which the search cannot be performed depending on an error recognition at the time of the recognition by the OCR is eliminated. It is an object of the invention to realize a process such that no burden is exerted on an operator or an apparatus by the above state. There are provided an OCR processor for recognizing stored image information and outputting a recognition result while switching the number of candidate characters to be outputted as a recognition result in accordance with a degree of a likelihood; and a document searcher for forming character trains for search from the recognition result and for registering as a search file.
