An image processing apparatus which performs reduction processing for rendering data in accordance with a reduction ratio, the apparatus comprises edge extraction unit that extracts edges from a contour of an object in the rendering data; saved line specification unit that specifies, out of lines including the edges extracted by the edge extraction unit, lines each having an outer shape feature of the object as saved lines which are lines not subjected to thinning processing; and thinning processing unit that thins out lines other than the saved lines in the object, thereby performing the reduction processing for the rendering data, wherein the saved line specification unit specifies saved lines by determining the outer shape feature of the object in accordance with characteristics of the edges. |
