Patent ID: 8234254

Claim:
An image recognition apparatus comprising: a storage device; and a processor, with regard to an image in which individual character strings are depicted as each of a plurality of logical elements configuring a logical structure, to recognize each of the logical elements based on a general logical structure model set in such a way as to correspond to the logical structure, to store the recognition result in the storage device, to collect information on the image of the logical structure to be processed with the general logical structure model, to acquire a recognition result that is recognized based on a post-update structure model regarding a logical structure image stored in the storage device that corresponds to a pre-update logic structure model, by processing the collected information with the post-update logical structure model when the general logical structure model is updated to a new logical structure model in such a way as to correspond to a new logical structure, to which the general logical, to compare whether or not a recognition result when the information collected is processed with the general logical structure model, and the recognition result acquired from the post-update logical structure model, match, and to output warning information indicating a warning about the post-update logical structure model to an output unit in a case in which a result of the comparison is a non-match.
