Abstract

A system and method of displaying identification information for a projector system are disclosed. The method includes projecting a display onto a viewing surface with the projector system, and projecting an identification image onto the viewing surface over at least a part of the display with the projection system, wherein the identification image is configured to convey the identification information to a viewer.

Claims

1. An image display system comprising:

memory configured to store a user-selected identification image, wherein the identification image includes information regarding the identity of the image display system; and

a display configured to project the user-selected identification image onto a viewing surface.

2. The image display system of claim 1 wherein the display is further configured to project a password prompt, wherein entry of an authorized password may enable display of content.

3. The image display system of claim 1, wherein the identification image is displayed over a content image.

4. The image display system of claim 1, wherein the identification image is displayed over a default image.

5. The image display system of claim 2, wherein the identification image is absent during content display.

6. The image display system of claim 2, wherein the identification image is displayed over a content image.

7. A system for preventing unauthorized use of a projector, the system comprising:

memory linked with user-selected security information;

a display configured to display a security image, wherein the security image requests the user-selected security information, wherein the display is further configured to display user content information upon receipt of the user-selected security information.

8. The system of claim 7, wherein the user-selected security information is stored on the projector.

9. The system of claim 7, wherein the user-selected security information is stored on an external computer used to control the projector.

10. The system of claim 7, further comprising

an input.

11. The system of claim 10, wherein the input is on the projector.

12. The system of claim 7, wherein the user-selected security information is prestored by an administrator.

13. The system of claim 7, wherein the user-selected security information includes at least one of a password and a username.

14. A display system comprising:

a user-selectable projector identity, including information regarding the identity of the projector;

memory configured to store the user-selectable projector identity; and

a means for displaying the user-selectable projector identity.

15. The display system of claim 14, where the user-selectable projector identity is displayed upon a select condition, including powering up, exiting a sleep mode and expiration of a predetermined time period of inactivity.

16. The display system of claim 14, wherein the user-selectable projector identity includes security information.

17. The display system of claim 16, wherein the means for display the user-selectable projector identity includes a request for the security information.
