Embodiment Construction

[0023] Much effort has been expended to design techniques to reduce the power consumption of electronic devices. Mobile devices in particular benefit from these efforts because reduced power consumption extends battery life, allowing these devices to be used for a longer amount of time before the battery needs to be recharged. Approaches to reducing power consumption may focus at least some of their attention on reducing power consumption of display devices. The major energy sources associated with a display device are the backlight, the active matrix of the liquid crystals, and the processor tasked with generating the pixel data for display on the device. For example, some LED-backlit TVs have been designed with an array of LEDs positioned behind an array of liquid crystal elements so that the brightness of the backlight can be dimmed in areas of the screen associated with darker colors. Local area dimming can significantly reduce the power consumed by the display device.

Abstract

The present invention provides a system, a computer readable medium, and a method for reducing the power consumption of a mobile device. The method includes the steps of: detecting video content to be viewed in an application executed by the mobile device; detecting unwanted content associated with the video content; and operating the mobile device in a low-power mode during playback of the video content in the application in response to detecting the unwanted content. The mobile device may include a memory storing the application and a processor executing the application, which configures the processor to implement the method. Five techniques may be applied in the low-power mode to reduce power consumption including Dynamic Voltage and Frequency Scaling (DVFS), reducing resolution of content, reducing brightness of a display, masking content, and thread throttling. The low-power mode saves energy when playing back videos on the mobile device.
