ABSTRACT:
According to one aspect of the invention, an image processing apparatus scales the image size and places one image onto another to display a compose image. The image processing apparatus includes an input image storage, an image attribute storage, an internal working memory, an output image storage, a processing unit block calculator, and an image processor. The processing unit block calculator dynamically determines a processing unit block according to the size of the internal working memory, scaling factors, a display image position, a display image size, and the amount of processed image data. The image processor inputs the image data of front and back images based on the processing unit block and performs composition processing in each processing unit block by using the internal working memory.
