Abstract

Arrangements and methods are provided that modulate various display device outputs in response to detected changes in environmental conditions affecting a display screen. The arrangement responds to changing environments to maximize the quality of the display. A sensor that is responsive to the changing environment, such as changes in ambient light, is provided to modulate the display accordingly. The arrangement contains logic for utilizing the sensing input and user preferences to provide the best display under the prevailing conditions.

Claims

1. An apparatus comprising:

a display device, wherein the display device comprises;

an arrangement adapted to ascertain at least one environmental condition; and

an arrangement adapted to modulate at least one display setting of the display device, wherein the at least one display setting comprises at least one operating system setting and is modulated based on the at least one ascertained condition.

2. The apparatus according to claim 1 wherein the at least one ascertained environmental condition is ambient light.

3. The apparatus according to claim 1 wherein the at least one ascertained environmental condition is a geographic location.

4. The apparatus according to claim 1 wherein the at least one operating system setting is selected from a group consisting of an inverse font setting, an inverse display setting, an enlarged text setting, and a display zoom setting.

5. The apparatus according to claim 1 wherein the display device is a projection screen arrangement.

6. The apparatus according to claim 1 wherein the display device is a monitor arrangement of a computer.

7. A system comprising:

a computer having a processor and a memory;

a display device operatively connected to the computer;

an arrangement adapted to ascertain at least one environmental condition; and

an arrangement adapted to modulate at least one display setting of the display device, wherein the at least one display setting comprises at least one operating system setting and is modulated based on the at least one ascertained condition.

8. The system according to claim 7 wherein the at least one ascertained environmental condition is ambient light.

9. The system according to claim 7 wherein the at least one ascertained environmental condition is a geographic location.

10. The system according to claim 7 further comprising a memory adapted to store at least one user display setting preference, wherein the at least one display setting is modulated to conform to the at least one user display setting preference.

11. The system according to claim 10 wherein the at least one user display setting preference is adapted to compensate for a bright light environment.

12. The system according to claim 7 wherein the at least one operating system display setting is selected from a group consisting of an inverse font setting, an inverse display setting, an enlarged text setting, and a display zoom setting.

13. The system according to claim 7 wherein the display device is a projection screen arrangement.

14. The system according to claim 7 wherein the display device is a monitor arrangement of a computer.

15. A method comprising:

ascertaining at least one environmental condition;

modulating at least one display setting of a display device based upon the at least one ascertained environmental condition;

wherein the at least one display setting to be modulated comprises at least one operating system setting selected from the group consisting of an inverse font setting, an inverse display setting, an enlarged text setting, and a display zoom setting.

16. The method according to claim 15 wherein the at least one ascertained environmental condition is ambient light.

17. The method according to claim 15 wherein the at least one ascertained environmental condition is a geographic location.

18. The method according to claim 15 wherein the at least one operating system setting is modulated base upon a stored user display setting preference.

19. A computer readable medium readable by a computer tangibly embodying a program of instructions executable by the computer to perform method steps for modulating at least one operating system setting of a display device, said method comprising the steps of:

ascertaining at least one environmental condition;

modulating at least one display setting of a display device based upon the at least one ascertained environmental condition;

wherein the at least one display setting to be modulated comprises at least one operating system setting selected from the group consisting of an inverse font setting, an inverse display setting, an enlarged text setting, and a display zoom setting.
