Abstract

A method for optimizing an appearance of a projected image. The method includes providing a first configuration having a plurality of preset projection device settings for a first type of projected image and providing a second configuration having a plurality of preset projection device settings for a second type of projected image. The method further includes selecting one of the first configuration and the second configuration, and automatically adjusting the respective plurality of preset projection device settings in accordance with the selection of one of the first configuration and the second configuration.

Claims

1. A projection device configured to display a plurality of types of projected images, comprising:

a memory;

a plurality of user-adjustable settings for adjusting an appearance of a projected image;

at least one set of preset values of the user-adjustable settings stored in the memory; and

a processor linked to the memory and configured to automatically adjust the user-adjustable settings to the preset values in accordance with selection of the set of preset values by the user.

2. The projection device of claim 1, wherein the set of preset values of the user-adjustable settings is manufacturer-defined.

3. The projection device of claim 2, wherein the manufacturer-defined set of preset values is optimized for at least one of presentations, photographs, film, and video.

4. The projection device of claim 1, wherein the set of preset values of the user-adjustable settings is user-defined.

5. A projection device configured to display a plurality of types of projected images, comprising:

a memory;

a processor linked to the memory;

a plurality of user-adjustable settings for adjusting an appearance of a projected image;

a set of preset values of the user-adjustable settings stored in the memory;

a first user input operable by a user to change at least one of the plurality of user-adjustable settings; and

a second user input operable by a user to direct the processor to automatically adjust the plurality of user-adjustable settings to the set of preset values.

6. The projection device of claim 5, wherein the memory contains a plurality of sets of preset values selectable by the user.

7. The projection device of claim 5, wherein the set of preset values is manufacturer-defined.

8. The projection device of claim 5, wherein the set of preset values is user-defined.

9. The projection device of claim 5, wherein the preset values are optimized for the display of a selected type of image of the plurality of types of images.

11. The projection device of claim 5, wherein the first and second user inputs are located on a surface of the projection device.

10. A projection device configured to display a plurality of projected images having different types of content, comprising:

a memory;

at least one set of preset values of user-adjustable settings stored in the memory, wherein the at least one set of preset values are selected from a plurality of user-adjustable settings for adjusting an appearance of a projected image;

a user input configured to allow the set of preset values to be selected by the user; and

a processor linked to the memory and configured to automatically adjust the user-adjustable settings to the preset values in response to selection of the set of preset values by the user.

12. The projection device of claim 10, wherein the user input is located on a surface of the projection device.

13. The projection device of claim 10, wherein the user selects the set of preset values from a menu projected by the projection device.
