Abstract:
An image-processing apparatus identifies a numeral recognition target range in an image, extracts, when a circumscribed rectangle of a numeral likelihood portion that is likely to represent a numeral in the numeral recognition target range conforms to a reference size, the circumscribed rectangle, extracts, when a plurality of circumscribed rectangles extracted are arrayed, the arrayed circumscribed rectangles, determines whether the circumscribed rectangles extracted each include one or both of a horizontal line and a vertical line, each of the horizontal line and the vertical line constituting a segment in a multiple-segment character, and extracts, as a target area for numeral identification, the circumscribed rectangle that includes one or both of the horizontal line and the vertical line, and isolates a numeral display area from the numeral recognition target range so as to include the target area in a predetermined direction.
