Abstract: An apparatus for manipulating a face image such as a portrait which produces visual effects to keep interesting a user with simple processes without requiring preparation of a complex model and a number-crunching process for processing the model is provided. Boundary determining means (111) determines a boundary used for bending a face image in a vertical direction of a face image. Image manipulating means (116) bends the face image based on the boundary as determined, to make the face image convex or concave locally around the boundary. Thereafter, the image manipulating means (116) rotates the face image about a rotation axis defined so as to extend in a horizontal direction of the face image, and thereafter projects the face image onto a plane. With those procedures, an expression of a face of the face image can be varied.
