Abstract

A method for operating a color display of a mobile device is provided. According to the method, a usage condition of the mobile device is detected and based on the detected usage condition a color scheme of information displayed on the color display is automatically adapted.

Claims

1. A method for operating a color display of a mobile device, the method comprising:

detecting a usage condition of the mobile device, and

automatically adapting a color scheme of information displayed on the color display based on the detected usage condition,

wherein detecting the usage condition of the mobile device comprises detecting a light intensity in an environment of the mobile device, and wherein adapting the color scheme comprises at least one of;

increasing a wavelength of at least one color of the information displayed on the color display with a decreasing light intensity,

shifting of at least one color of the information displayed on the color display from a blue spectrum to a red or green spectrum with a decreasing light intensity,

decreasing a wavelength of at least one color of the information displayed on the color display with an increasing light intensity,

shifting of at least one color of the information displayed on the color display from a red spectrum to a green or blue spectrum with an increasing light intensity,

decreasing a color saturation of the information displayed on the color display with an increasing light intensity, or

displaying a black and white representation of the information on the color display when the light intensity exceeds a predetermined threshold.

2. The method according to claim 1, further comprising:

automatically adapting a brightness of the information displayed on the color display based on the detected usage condition.

3. The method according to claim 2, wherein detecting the usage condition of the mobile device comprises detecting a light intensity in an environment of the mobile device, and wherein adapting the brightness comprises decreasing the brightness of the information displayed on the color display with a decreasing light intensity.

4. The method according to claim 1, further comprising:

automatically adapting a contrast of the information displayed on the color display based on the detected usage condition.

5. The method according to claim 4, wherein detecting the usage condition of the mobile device comprises detecting a light intensity in an environment of the mobile device, and wherein adapting the contrast comprises increasing the contrast of the information displayed on the color display with an increasing light intensity.

6. The method according to claim 1, wherein detecting the usage condition of the mobile device comprises at least one of a group comprising:

detecting a light intensity in an environment of the mobile device,

detecting a time of day, and

detecting a kind of an application whose information is displayed on the color display.

7. The method according to claim 1 wherein adapting the color scheme comprises:

selecting a color scheme from a look-up table based on the detected usage condition, and

applying the selected color scheme to the information displayed on the color display.

8. A mobile device comprising:

a color display adapted to display information to a user of the mobile device,

a processing unit, coupled to the color display and adapted to detect a usage condition of the mobile device and automatically adapt a color scheme of the information displayed on the color display based on the detected usage condition,

wherein the processing unit is adapted to detect the usage condition of the mobile device by detecting a light intensity in an environment of the mobile device, and wherein the processing unit is adapted to adapt the color scheme by at least one of;

increasing a wavelength of at least one color of the information displayed on the color display with a decreasing light intensity,

shifting at least one color of the information displayed on the color display from a blue spectrum to a red or green spectrum with a decreasing light intensity,

decreasing a wavelength of at least one color of the information displayed on the color display with an increasing light intensity,

shifting at least one color of the information displayed on the color display from a red spectrum to a green or blue spectrum with an increasing light intensity,

decreasing a color saturation of the information displayed on the color display with an increasing light intensity, or

displaying a black and white representation of the information on the color display when the light intensity exceeds a predetermined threshold.

9. The mobile device according to claim 8, wherein the mobile device comprises at least one mobile device of a group consisting of a mobile phone, a personal digital assistant, a mobile music player, a mobile computer, and a mobile navigation system.
