An image recognition apparatus recognizes the correspondence between character strings and logical elements composing a logical structure in an image in which the character strings are described as the logical elements to recognize each logical element. The image recognition apparatus includes outputting means for outputting the recognized logical elements when the correspondence is recognized or re-recognized; first determining means for determining a certain logical element to be correct when input of a determination request to determine the logical element is received from a user; second determining means for determining the correctness of all the logical elements output before the logical element determined by the first determining means and is positioned according to confirmation by the user; and re-recognizing means for re-recognizing the correspondence between logical elements that have not been determined to be correct and the character strings on the basis of the determination content for each logical element.

Matching between a reference image and an input image is performed without relying on specific elements such as line segments or tables. An edge image is generated from the reference image and divided into small blocks, and search range and search priority of each small block are determined and stored in a storage device. When an input image is input, an edge image thereof is generated. The small blocks in the reference image are retrieved in order of priority, and matching with the input image is judged. When the corresponding position of one small block is determined, the search range and search priority for other small blocks not yet judged for matching are updated on the basis of the determined corresponding position.
