Abstract: A projector includes a connection unit to which a portable terminal device is connected, a memory unit configured to store identification data of the portable terminal device to be permitted or denied, and a determination unit configured to determine whether to permit or deny use of the projector based on identification information of the portable terminal device received from the portable terminal device connected to the connection unit and the identification data.

Abstract: The image display device and the like may generate an OSD image with the contents at the time of temporary non-display instruction when there is a redisplay instruction after temporary non-display instruction of a normal OSD image. As a result, the user can perform adjustment and the like of an image using an OSD image more efficiently. Since the image display device and the like generate a second OSD image showing temporary non-display at the time of temporary non-display of a normal OSD image, the user can see that the normal OSD image is in a temporary non-display state. In addition, since the size of the second OSD image is small, almost the entire original image can be checked.
