Disclosed is a method for generating a resultant image as if said image were drawn from an image by an artist, and a device for executing same. The device includes: a first generating unit for generating a vector field relating to the image using a feature pixel in a received image and direction information on the specific pixel; a second generating unit for generating a structure grid using the vector field; a rendering unit for rendering a primitive version that expresses a predetermined tone on the generated structure grid; and an image-generating unit for generating a resultant image by adding a feature line to the result of the primitive version rendering. Accordingly, a resultant image may be quickly generated from one image. This allows a hedcut to be easily generated using one picture, thereby overcoming the limitation of the lengthy period of time a hedcut artist takes to complete one hedcut picture.
