Abstract
An image synthesizing system is provided that can prevent image deterioration resulting from synthesis applied to a predictive image to be used for the next frame. The image synthesizing system decodes and synthesizes a main frame and a sub-image compressed in different modes. The image synthesizing system includes a main image frame buffer , an alpha blending section , and an image synthesis and display . The main image frame buffer stores a main image to be referred to in the next frame decoding process. The alpha blending section alpha-blends a main image from the main image frame buffer with a decoded sub-image to produce a translucent composite image. The image synthesis and display superimposes the translucent composite image on the main image.
