Image display device, projector, and method of controlling the same

A projector comprising:

• an image reproduction section adapted to reproduce image information recorded on a recording medium mounted;
• an image display section adapted to display an image corresponding to the image information reproduced by the image reproduction section;
• a control section adapted to make the image reproduction section start reproduction of the image information if the recording medium is mounted to the image reproduction section;
• and
• an authentication section adapted to perform user authentication,
• wherein the control section inhibits the image reproduction section from reproducing image information until the user authentication by the authentication section becomes successful, and
• the image display section performs an image projection to project the image corresponding to the image information reproduced by the image reproduction section.

A method of controlling an image display device having an image reproduction section adapted to reproduce image information recorded on a recording medium mounted, comprising:

• (a) detecting a loading operation adapted to load the recording medium from outside and mount the recording medium to the image reproduction section;
• (b) performing user authentication if the loading operation is detected;
• and
• (c) inhibiting reproduction of the image information by the image reproduction section if the user authentication is unsuccessful in step (b).
