Patent ID: 8706911

Claim:
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.
