An image processing apparatus includes an edge detecting unit, a rectangular object detecting unit, and an arrangement processing unit. The edge detecting unit is configured to (a) search each target line in a page image that includes plural rectangular objects for edges of the plural rectangular objects, and (b) detect the edges of the plural objects on the target line on the basis of density variation between pixels in the target line. The rectangular object detecting unit is configured to (a) detect the plural rectangular objects on the basis of the detected edges, and (b) determine respective positions, respective sizes and respective tilt angles of the plural rectangular objects. The arrangement processing unit is configured to rotate areas of the plural rectangular objects specified by the determined positions, the determined sizes and the determined tilted angles by angles corresponding to the tilted angles, respectively. |
