<p>PURPOSE:To look straight a window from any arbitrary direction at real time by rotating the window by providing a body structure for management concerning the window and applying the value of a rotating angle to the body structure. CONSTITUTION:A CPU 35 traces a body structure list for management in a main memory 34, when the body structure for management of the target window is found out, an image processing list is generated by using coordinate information and sent to an image processor 32. At such a time, the information of the rotating angle is contained in an image processing request by using the rotating angle stored in the body structure for management. The image processor 32 receives the image processing request, processes the image data of the window in a local memory 31 and stores the result in a frame buffer 33. When the rotating angle information is contained in the request for image processing at such a time, the image processor 32 rotates the designated image data in the local memory 31 at high speed and stores the result in the frame buffer 33.</p> |
