通过动态分辨率缩放来减少移动设备的功耗
摘要：
本发明涉及通过动态分辨率缩放来减少移动设备的功耗。一种计算设备可以至少部分地基于计算设备的用户与显示器之间的查看距离来动态地调节像素密度。在一些示例中，查看距离可以使用低功率声学(例如超音)感测来确定。用来显示内容的像素密度可以使用基于查看距离和用户的视觉敏锐度的算法来确定。要在计算设备上显示的内容可以被发送给计算设备的处理器以供图形处理。在一些示例中，内容可以在处理之前被截取(诸如通过使用挂钩进程)并且基于所确定的像素密度被缩放。通过缩小内容的像素密度，用于处理内容所要求的系统资源量可以更少，这可进而导致处理器用于执行图形处理操作的更少的功耗，从而延长计算设备的电池寿命。
摘要（英）：

A computing device may dynamically adjust a pixel density based at least in part on a viewing distance between a user and a display of the computing device. In some examples, the viewing distance may be determined using low power acoustic (e.g., ultrasonic) sensing. A pixel density at which to display content may be determined using algorithms based on the viewing distance and a visual acuity of a user. Content to be displayed on the computing device may be sent to processors of the computing device for graphics processing. In some examples, the content may be intercepted, such as by using a hooking process, before processing and scaled based on the determined pixel density. Scaling down the pixel density of the content may require less system resources to process the content, which may result in less power consumption by the processors to perform the graphics processing operations.
