Patent ID: 7006153

Claim:
An image composition method for compositing a first image signal with a second image signal, the first image signal forming a first image space, and comprising a shape signal indicating the shape of an arbitrary-shaped object and a texture signal indicating the texture of the object, the second image signal forming a second image space and comprising a texture signal indicating the texture of an image, said method comprising: determining a composition position of the arbitrary-shaped object in the first image space based on at least a composition control signal for controlling image composition; determining the shape and boundary of an arbitrary-shaped frame of the arbitrary-shaped object based on at least the shape signal, and an arbitrary-shaped frame control signal for controlling generation of the arbitrary-shaped frame; generating an arbitrary-shaped frame based on at least the shape and boundary information that is obtained in the shape and boundary determination and the arbitrary-shaped frame control signal; forming an arbitrary-shaped frame image in which the frame is added to the arbitrary-shaped object; and compositing the image of the arbitrary-shaped object in the first image space or the generated arbitrary-shaped frame image, with the corresponding image in the second image space, thereby generating a composite image that forms the third image space.
