Abstract
An image processing system is connected to a display device for displaying an image comprising a plurality of frames. The system comprises first and second processors, input controller for receiving positional information from a user via an input device connectable to the image processing system, and a shared memory accessible by the first and second processors for storing data representing frames of an image, and the positional information. The first processor is arranged to load frames of the image from a storage device in to the shared memory, for each frame the first processor being arranged to retrieve from the storage device data representing that frame, to load the frame data into the shared memory, and to store in the shared memory frame address information identifying the location within shared memory of the frame data and the positional relationship of the frame to other frames of the image. Further, the first processor accesses the positional information to determine in what order to load the frames of the image in to shared memory. In parallel, the second processor is arranged to access the positional information to determine a portion of the image to be displayed, and …
