IMAGE SYNTHESIZING DEVICE, RECORDED MEDIUM, AND PROGRAM

摘要

An image compositing apparatus of the present invention composites a video image and a plurality of graphical images' together into a final composite image. The image compositing apparatus includes a first obtaining unit, a first compositing unit, a calculating unit, a second obtaining unit, and a second compositing unit. The first obtaining unit obtains the graphical images and composition information that includes an image compositing order and is used for calculating the composition ratios of the images to the final composite image. The first compositing unit composites the graphical images together into one composite graphical image according to the composition information. The calculating unit calculates the composition ratio of the video image to the final composite image according to the composition information. The second obtaining unit obtains frames of the video image. The second compositing unit composites the frames with the composite graphical image using the composition ratio of the video image.
