Abstract: A method and system for image blending is disclosed. A destination image is received (100), the destination image including an image portion to be replaced and having characteristics associated with the identified image portion. A source image is also received (130). An image portion of the source image to be inserted into the destination image is identified (140). Where necessary, parameters of the image portion to be inserted are transformed to match those of the image portion to be replaced (150). The image portion to be inserted is then blended into the destination image in dependence on the image portion to be replaced and its associated characteristics (160). A video generation system using these features is also disclosed.
