Abstract
An edge image generating unit detects edge pixels in an original image and generates an edge image that includes the detected edge pixels. A reduction processing unit sets a reduction direction as a horizontal or a vertical direction, and reduces the edge image along the reduction direction by a predetermined reduction ratio without reducing the original image along a direction perpendicular to the reduction direction and thereby generates a reduced image. A connecting pixel group detecting unit detects, in the reduced image, a connecting pixel group continuously extending along the reduction direction. A ruled line determining unit associates two connecting pixel groups with each other as a connecting pixel group pair among the detected connecting pixel groups, and determines a position of a ruled line in the original image from a position of the connecting pixel group pair on the basis of the reduction ratio.
