Abstract

Display information to be displayed by a display device having a power consumption model is converted according to a power-saving conversion model and the power consumption model, such that the power consumption of the display device for displaying the converted display information is lower than that for displaying the original display information.

Claims

1. A hardware proxy server, comprising:

a processor configured for

receiving display information to be displayed by a display device having a power consumption model;

converting the received display information according to a power-saving conversion model and the power consumption model; and

providing the converted display information to the display device,

wherein, according to the power consumption model, power consumption of the display device for displaying the converted display information is lower than that for displaying the display information received by the proxy server,

wherein the power-saving conversion model comprises at least one of an image conversion model or an image descriptor conversion model,

wherein the image conversion model comprises at least one of;

a brightness reduction model, for reducing a pixel brightness of at least one pixel of an image of the display information;

or

a color conversion model, for converting an original pixel color of said at least one pixel of the image into a power-saving color which, according to the power consumption model, requires less power to display than the original pixel color, and

wherein the image descriptor conversion model comprises at least one of;

a color theme conversion model, for converting an original color theme defined by at least one image descriptor of the display information into a power-saving color theme which, according to the power consumption model, requires less power to display than the original color theme;

an image descriptor dimming model, for reducing brightness defined by said at least one image descriptor;

an image descriptor resizing model, for reducing a display size defined by said at least one image descriptor;

or

an image descriptor removing model, for removing said at least one image descriptor.

2. The proxy server according to claim 1, wherein the at least one image descriptor includes at least one of markup language code, program code, or color theme configuration code.

3. The proxy server according to claim 1, further comprising

a storage device for storing at least one of the power-saving conversion model or the power consumption model.

4. The proxy server according to claim 1, wherein

the power consumption model contains data on power consumption of the display device for displaying various colors at various brightness;

and

the processor is configured to calculate power consumption of the display device for displaying the received or converted display information by using said data of the power consumption model.

5. A display information converting system, comprising:

a display device having a power consumption model; and

a proxy server coupled to the display device for

receiving display information to be displayed by the display device;

converting the received display information according to a power-saving conversion model and the power consumption model; and

providing the converted display information to the display device,

wherein, according to the power consumption model, power consumption of the display device for displaying the converted display information is lower than that for displaying the display information received by the proxy server,

wherein the power-saving conversion model comprises at least one of an image conversion model or an image descriptor conversion model,

wherein the image conversion model comprises at least one of;

a brightness reduction model, for reducing a pixel brightness of at least one pixel of an image of the display information;

or

a color conversion model, for converting an original pixel color of said at least one pixel of the image into a power-saving color which, according to the power consumption model, requires less power to display than the original pixel color, and

wherein the image descriptor conversion model comprises at least one of;

a color theme conversion model, for converting an original color theme defined by at least one image descriptor of the display information into a power-saving color theme which, according to the power consumption model, requires less power to display than the original color theme;

an image descriptor dimming model, for reducing brightness defined by said at least one image descriptor;

an image descriptor resizing model, for reducing a display size defined by said at least one image descriptor;

or

an image descriptor removing model, for removing said at least one image descriptor.

6. The display information converting system according to claim 5, wherein the display device is a pixel self-emissive display device.

7. A display information converting method, comprising:

receiving display information to be displayed by a display device having a power consumption model;

converting the received display information according to a power-saving conversion model and the power consumption model; and

providing the converted display information to the display device,

wherein, according to the power consumption model, power consumption of the display device for displaying the converted display information is lower than that for displaying the received display information, and

wherein said converting comprises at least one of;

reducing a pixel brightness of at least one pixel of an image of the display information by using a brightness reduction model,

converting an original pixel color of said at least one pixel of the image into a power-saving color by using a color conversion model, wherein the power-saving color, according to the power consumption model, requires less power to display than the original pixel color,

converting an original color theme defined by at least one image descriptor of the display information into a power-saving color theme by using a color theme conversion model, wherein the power-saving color theme, according to the power consumption model, requires less power to display than the original color theme,

reducing brightness defined by said at least one image descriptor by using an image descriptor dimming model,

reducing a display size defined by said at least one image descriptor by using an image descriptor resizing model, or

removing said at least one image descriptor by using an image descriptor removing model.

8. The display information converting method according to claim 7, between receiving the display information and converting the received display information, further comprising:

receiving a plurality of parameters; and

using the parameters and the power-saving conversion model in said converting the display information.

9. The display information converting method according to claim 7, wherein

the power consumption model contains data on power consumption of the display device for displaying various colors at various brightness;

and

said converting comprises calculating power consumption of the display device for displaying the received and converted display information by using said data.

10. The display information converting method according to claim 7, wherein said converting further comprises

determining whether the converted display information satisfies a predetermined power-saving requirement;

and

if it is determined that the converted display information does not satisfy the predetermined power-saving requirement, repeating at least one of

said reducing the pixel brightness of said at least one pixel,

said converting the original pixel color of said at least one pixel,

said converting the original color theme defined by said at least one image descriptor,

said reducing brightness defined by said at least one image descriptor,

said reducing the display size defined by said at least one image descriptor, or
