Abstract: A device implementing a system for displaying an image includes a processor configured to, generate, during a first power state of a device, a data structure specifying image frames and a respective display time for each of the image frames, and retrieve, during a second power state of the device and from the data structure, an image frame based on the respective display time for the image frame. The at least one processor is further configured to display, during a third power state of the device, the retrieved image frame on a display of the device.

Abstract: This disclosure pertains to systems, methods, and computer readable medium for mapping particular user interactions, e.g., gestures, to the input parameters of various image processing routines, e.g., image filters, in a way that provides a seamless, dynamic, and intuitive experience for both the user and the software developer. Such techniques may handle the processing of both “relative” gestures, i.e., those gestures having values dependent on how much an input to the device has changed relative to a previous value of the input, and “absolute” gestures, i.e., those gestures having values dependent only on the instant value of the input to the device. Additionally, inputs to the device beyond user-input gestures may be utilized as input parameters to one or more image processing routines. For example, the device's orientation, acceleration, and/or position in three-dimensional space may be used as inputs to particular image processing routines.

Abstract: Improved techniques of managing graphical user interface (GUI) objects based on portal layers (or simply portals) are described. A portal refers to a logical reference to a GUI object specified by an application that enables an operating system to access and process the specified GUI object without affecting any of the rules/assumptions required by the application for the specified GUI object. Portals can assist with reducing computational resources required for rendering by assisting with reducing or eliminating the use of snapshots for rendering. One embodiment includes generating a layer tree; identifying a first sub-tree of the layer tree as portal content; establishing a portal as a reference to the portal content in a second sub-tree of the layer tree; generating a render tree based on the layer tree; rendering the render tree to create an image; and presenting the image on a display.

Abstract: Embodiments provide for a display system to generate and display data on a display device, the display system comprising one or more graphics processors to generate one or more frames of data for display on the display device; a display engine to present the one or more frames of data to the display device for display; display logic to receive a request to display the one or more frames of data and generate one or more display events for the display engine based on the request, wherein the request includes a first hint to indicate a complexity of the one or more frames of data and the one or more display events includes a second hint derived from the first hint; and a performance controller to adjust one or more performance related parameters for the display system based on the second hint.

Abstract: Prior art attempts to manage authority designation in GUI-based computer systems have set up various “handshaking” schemes between a graphics management system, such as a window server, and the various processes that are attempting to offer and accept access to each other. However, these schemes have certain limitations. In particular, when windows are used as the “fundamental basis” for implementing authority designation, events that should treat all content within a window identically can't do so because, even though all content in the window may appear to be “owned” by the window, there may be some other process that is actually rendering the content to some portion of the window. Thus, described herein are systems and methods to manage authority designation and event handling within “hierarchical” GUIs using “handshaking” schemes that are secure, sub-window granular, and that generalize recursively when applied to the various graphical layers used to construct the windows.

Abstract translation: 在基于GUI的计算机系统中管理权限指定的现有技术尝试已经在图形管理系统（例如窗口服务器）和尝试提供并接受彼此访问的各种进程之间建立了各种“握手”方案。 然而，这些方案有一定的限制。 特别是，当窗口被用作执行权限指定的“基础”时，应该对窗口内的所有内容进行相同处理的事件不能这样做，因为即使窗口中的所有内容可能看起来都被“拥有” 窗口中，可能还有一些其他的过程实际上是将内容渲染到窗口的某个部分。 因此，这里描述的是使用安全，子窗口粒度的“握手”方案来管理“分层”GUI内的权限指定和事件处理的系统和方法，并且当应用于用于构建窗口的各种图形层时递归地概括 。

Abstract: Disclosed herein is a technique for implementing a secure lock screen on a computing device. The secure lock screen is configured to permit particular applications to display their content—such as main user interfaces (UIs)—while maintaining a desired overall level of security on the computing device. Graphics contexts, which represent drawing destinations associated with the applications, are tagged with entitlement information that indicates whether or not each graphics context should be displayed on the computing device when the computing device is in a locked-mode. Specifically, an application manager tags each application that is initialized, where the tagging is based on a level of entitlement possessed by the application. In turn, a rendering server that manages the graphics contexts can identify the tagged entitlement information and display or suppress the content of the applications in accordance with their entitlements.
