• external action input means, for receiving an external action;
• a frame memory, for storing, as frames, said image data received by said plurality of image data input means;
• transfer means, for reading said image data from said frame memory and for transferring said image data to said display device;
• detection means, for detecting the sum of the input data transmission rates for said image data that are received by said plurality of image data input means;
• comparison means, for comparing the sum obtained for the input data transmission rates with a data transmission rate for said frame memory;
• priority allocation means, for determining and allocating display priorities for said image data sets to be displayed on said display device in accordance with said external action;
• and
• control means, for controlling the display, on said display device, of said received image data sets in accordance with said display priorities and the result obtained by the comparison of the data transmission rate for said frame memory with the sum detection for the input data transmission rates.
