Systems and methods for controlling the lighted display of a mobile device are disclosed. The backlight of or active power supplied to a display is reduced or deactivated after a certain period based on the application running on the mobile device, rather than being a uniform deactivation time. The system and method can be used on a variety of mobile devices having a display screen.

Context sensitive backlight

A do not disturb (DND) mode for telephonic devices, in which the DND mode is automatically deactivated after a time increment has elapsed, the DND mode having been activated based on detecting, upon receiving a telephone call, a selection of the control.

Disruption blocking in mobile devices

The present disclosure provides methods and systems for storing image data in a mobile device. In some embodiments, the method includes generating an image on the mobile device, identifying automatically at least one person in the image, creating a cropped image of the at least one person and storing the cropped image to memory upon request of a user of the mobile device.

Contact cropping from images

Certain implementations of the disclosed technology may include systems and methods for improving image tracking based on touch events. A method is provided for outputting an image for presentation using an electronic device, the electronic device having a display refresh rate. The method includes detecting one or more touch events received via a touch sensitive surface screen associated with the electronic device, each touch event having a touch event position. The method also includes generating, by the electronic device, a synthetic touch event position based on the one or more touch event positions, the synthetic touch event position calculated to coincide in time with a predicted time, the predicted time being within an offset relative to a display refresh time corresponding to the display refresh rate. The method also includes outputting data based at least in part one or more of the synthetic touch event position or a touch event position associated with the one or more touch events.

Systems and methods for improving image tracking based on touch events

Methods and systems for acquiring and batching sensor data using a mobile device are described. In one example, a system in a mobile device is provided. The system includes one or more sensors, a memory, a sensor processor, and a main application processor. The sensor processor is configured to determine sensor data using the one or more sensors on an interval basis and store the sensor data into one or more first-in, first-out (FIFO) queues. Additionally, the sensor processor is configured to replace at least a portion of the stored sensor data if a main application processor of the mobile device does not request the stored sensor data within a certain amount of time. The main application processor is configured to receive data indicating a request for sensor data for a recent time period and, in response, to retrieve the sensor data from the one or more FIFO queues.

Determining sensor information in the background on a mobile device

Multi-window display operations may be optimized in an electronic device. The electronic device comprises a screen that may be operable to provide a multi-window display by enabling configuring of a plurality of display regions, where video content corresponding to one or more of the plurality of applications is displayed in each of the plurality of display regions. Optimizing multi-window display operations may comprise monitoring updates of video content for each of the plurality of display regions of the screen, and generating a frame comprising video content for all of the plurality of display regions when one or both of the following occurs: all pending video content updates are completed and a frame generation deadline is reached.

Coordinating distributed graphics rendering in a multi-window display

The subject matter of this specification can be embodied in, among other things, a method that includes computer-implemented graphics frame buffer process that establishes on a computing device a graphics frame buffer accessible to be written by an application process and to be read by a graphics server process. The method further comprises generating a plurality of control bits whose value or values control access to the frame buffer by the application process and the graphics server process and reading frames from the frame buffer using the value or values in the plurality of control bits.

Graphics display coordination

A method and system for boosting a clock frequency for a processor in a mobile device based on user interface (UI) demand are described. In response to a user interaction through a UI in the mobile device, a vertical synchronization pulse request is made by an application and an indication of such request can be provided to a governor. The governor can adjust a clock frequency of a processor in the mobile device based on the generated indication. The processor can be a central processing unit or a graphics processing unit. The clock frequency can be boosted to a higher frequency to increase the processing capabilities of the mobile device to handle the computational requirements of the user interaction. Some time after boosting the clock frequency of the processor, the governor can return to normal operations in which the clock frequency scaling is typically based on a measured system load.

Processor boost based on user interface demand

Systems and methods for a stencil-based overdraw visualizer are described. Mobile device that includes, for example, one or more memories and one or more processors operatively coupled to the one or more memories. The one or more memories include a stencil buffer. The one or more processors are configured to render graphics on a display based on an application that is running on the one or more processors; count overdraws in the stencil buffer on a pixel-by-pixel basis; associate respective colors with corresponding overdraw values stored in the stencil buffer; and combine rendered graphics on the display based on the application with the colors indicated in the stencil buffer on a pixel-by-pixel basis.
