1. An image processing device for generating a 3-D character image of a target object included in an input image, comprising: an image input section for inputting a face image; a storage section for prestoring plurality types of 3-D models of hair and faces, a plurality of body images, and information on a direction, position, and size of a face conforming to the body images; a user input section having a position designation means for designating an arbitrary position in the image input via the image input section and a body selection means for selecting the body image stored in the storage section; an image processing section, comprising a textured image generation means for generating, based on information representing a position designated by the position designation section, a textured image as viewed from a prescribed position and direction having a prescribed size so as to paste the input image onto the 3-D model, a textured image storage means for storing the textured image generated by the textured image generation section, a face image generation means for generating a 3-D still head image by rotating a 3-D face model according to the information on a direction, position and size of a face conforming to the body image, painting the hair, and pasting the textured image onto the 3-D face model, and a combining means for combining a body image selected by the body selection means and an image generated by the face image generation section so as to generate a 3-D character image; and a display section for displaying the 3-D character image generated by the image processing section.
