Abstract
An enlarged image is displayed using a plurality of television sets. A television set serving as a master device and television sets serving as slave devices convert an input image into partial enlarged images and display the resultant partial enlarged images so that the partial enlarged images displayed on the respective television sets form, as a whole, a complete enlarged full image. The master device and slave devices perform mutual authentication with each other. If the authentication is successfully passed, the operation mode is set so that displaying of an enlarged image is allowed.
