Portable media device with power-managed display
First Claim
1. A method for conserving power by controlling display intensity of a display device incorporated in a power limited portable electronic device for identified content to be displayed on the display device, the content having a content type associated therewith, wherein an external device wirelessly coupled to the portable electronic device determines the content type of the identified content and identifies a user preference set for the determined content type, the method comprising:
- receiving at the portable electronic device from the external device a brightness level for the identified content determined by the external device, wherein the brightness level for the identified content to be displayed is determined based on the identified user preference and determined content type associated with the identified content; and
after receiving the brightness level at the portable electronic device, adjusting an output intensity level for the display device of the portable electronic device based on the brightness level received.

Abstract
Improved techniques for controlling power utilization of a display device are disclosed. The improved techniques reduce power consumption by lowering display intensity at appropriate times. In one embodiment, the display intensity can be controlled depending on the type of content being displayed. In another embodiment, the display intensity can be controlled depending on the characteristics of the content being displayed. In still another embodiment, the display intensity can be controlled depending on the type and characteristics of content being displayed. The improved techniques are well suited for use with portable media devices.

18. A non-transitory computer readable medium storing at least executable computer program code for performing predisplay processing of content to be displayed, wherein the content comprises a plurality of different visual content types, comprising:
-
executable computer code for, on a host device, examining the content to identify a dominant content type from the plurality of different visual content types; executable computer code for determining a particular output intensity level associated with the dominant content type based on the identified dominant content type and a user preference associated with the identified content type; and executable computer code for sending the content to a portable media device along with information regarding the particular output intensity level after the executable computer code determines the particular output intensity level associated with the dominant content type, such that the portable media device can utilize the information to alter display intensity of a display to match the particular output intensity level without incurring a computational burden from examining the content to identify a dominant content type, wherein display intensity of the display can be altered after the portable media device receives the content and the information regarding the particular output intensity level. - View Dependent Claims (19, 20, 21)
