IMAGE PROCESSING APPARATUS, IMAGE EDITING APPARATUS, IMAGE EDITING METHOD, AND IMAGE EDITING PROGRAM

An image processing apparatus including a receiving unit, an extraction means, and a conversion means is disclosed. The receiving unit receives a first document data and a second document data obtained by reading respectively a first document and a second document each having at least one drawing. The extraction means extracts a first caption group for identifying the drawing contained in the first document and a second caption group for identifying the drawing contained in the second document. The conversion means converts the first caption group and the second caption group into a third caption group so that a character string in the first caption group does not overlap a character string in the second caption group.
