ABSTRACT:
An image composition apparatus includes a composition processing unit comprising a composition position determination unit for receiving a shape signal and an image signal which are outputted from an image decoding unit, and determining a composition position of an object as a foreground image; a shape boundary determination unit for determining the shape and boundary of the object; an arbitrary-shaped frame generation unit for generating an outline or frame of the object on the basis of information relating to the shape and boundary of the object; and a pixel composition unit for compositing a target pixel (pixel to be processed) of the object or an arbitrary-shaped frame pixel that is generated by the arbitrary-shaped frame generation unit4c,with the corresponding pixel in the background image. Therefore, a composite image, in which an outline or an arbitrary-shaped shape is added to an arbitrary-shaped object, can be generated.
