Provided are a method of generating a resulting image as if drawn by an artist and an apparatus for executing the method. The apparatus includes a first generation unit configured to generate a vector field expressing a shape of an image using feature pixels of the image captured by an image device and direction information of the feature pixels, a second generation unit configured to generate a structure grid indicating a structure for rendering the shape of the image using the vector field, and a rendering unit configured to render primitives expressing predetermined tones on the generated structure grid. Accordingly, it is possible to automatically and rapidly generate a resulting image from one image. Anyone can easily generate a hedcut from one photo without the limitation that a limited number of artists need to invest a great deal of time to complete one hedcut.
