Prior to rendering a current frame, a device obtains a previously rendered frame. The device determines that a first portion of the previously rendered frame is associated with a particular type of content. The device renders a first portion of the current frame that corresponds to the first portion of the previously rendered frame with a first rendering characteristic while rendering a second portion of the current frame with a second rendering characteristic that is different from the first rendering characteristic.

Content based foveation

A text messaging system that allows messaging apps to send one or more layer identifiers that can specify content for a layer and Z depth of that layer relative to other layers in a text message transcript such as a sent message layer and a received message layer.

Layers in messaging applications

A head-mounted device includes one or more displays configured to present media content. The media content may be presented in a user interface window. The head-mounted device may include a display controller configured to adjust a frame rate of the one or more displays and may include a frame rate management circuit configured to determine whether to adjust the frame rate of the one or more displays based on the type of the media content being presented in the user interface window and based on additional information such as a preferred frame rate associated with the media content, a size of the user interface window relative to the total display area of the one or more displays, point of gaze data, hand gestures data, head pose data, data associated with other body parts, audio information and other data.

Head-mounted electronic device with adjustable frame rate

A system may include multiple electronic devices. A first device such as a source electronic device may supply visual content for displaying by a display in a second electronic device such as a display electronic device. The display electronic device may be a television or other device with a display. Calibration operations may be performed by taking light measurements on light produced by the display when test content is provided from the first device to the second device. A third electronic device in the system such as a portable electronic device with an ambient light sensor may make measurement on the light from the display while the test content is being displayed. The test content may contain a test image target with time-varying color and time-varying intensity, allowing calibration information such as gamma curves to be obtained on the display.

Display calibration system

An electronic device may be provided with a display. A content generator may generate frames of image data to be displayed on the display. Control circuitry in the electronic device may be used in implementing a tone mapping engine. The tone mapping engine may display content from the content generator on the display in accordance with a content-luminance-to-display luminance mapping. The content-luminance-to-display-luminance mapping is characterized by tone mapping parameters such as a black level, a reference white level, and a specular white level. The tone mapping engine may adjust the tone mapping parameters based on ambient light levels, user brightness settings, content statistics, and display characteristics.

Electronic devices with tone mapping engines

One disclosed embodiment is directed to graphics processing method for displaying a user interface. The method includes executing a plurality of graphic processing operation in a single rendering pass. The rendering pass includes several render targets. At least one of the render targets is designated as a memory-less render target. The memory-less render target is used to store intermediate data. The intermediate data is combined with the outcome of at least one other graphics processing operation to generate a combined result. The combined result is stored in the frame buffer memory for display.

Eliminating off screen passes using memoryless render target

This disclosure pertains to the operation of graphics systems and to a variety of architectures for design and/or operation of a graphics system spanning from the output of an application program and extending to the presentation of visual content in the form of pixels or otherwise. In general, many embodiments of the invention contemplate a high level graphics framework to receive graphic requests from an application. The graphics request is analyzed by the high-level framework and sorted into groups of command statements for execution. The command statements are sorted to cause the most efficient processing by the underlying hardware and the groups are submitted separately to a GPU using a low-level standard library that facilitates close control of the hardware functionality.

Graphics engine and environment for efficient real time rendering of graphics that are not pre-known

Embodiments of the present disclosure are directed to methods and systems for displaying an image on a user interface. The methods and systems include components modules and so on for determining a minimum feature width of the image and determining and a distance field of each region associated with the image. The distance field of each region may be based on the minimum feature width. A filter threshold associated with the distance field is then determined and the image is output using the determined filter threshold.

A method and an apparatus for a parallel computing program calling APIs (application programming interfaces) in a host processor to perform a data processing task in parallel among compute units are described. The compute units are coupled to the host processor including central processing units (CPUs) and graphic processing units (GPUs). A program object corresponding to a source code for the data processing task is generated in a memory coupled to the host processor according to the API calls. Executable codes for the compute units are generated from the program object according to the API calls to be loaded for concurrent execution among the compute units to perform the data processing task.

Application programming interfaces for data parallel computing on multiple processors

A computing system that supports the use of multiple displays in display mirroring mode and extended display mode may automatically determine a display mode in which to configure the system (with little or no user input) based on various characteristics of the displays in the system. For example, the system may determine that a television, projector, or other presentation type display is connected in the system, and in response, may determine that the system should be configured in a display mirroring mode, rather than in an extended display mode. The system may also determine that the presentation type display is the preferred display, and may render image content in a best (or preferred) mode for that display using its native resolution, aspect ratio or color profile. The system may then scale the rendered image content for display on other (non-preferred) displays, such as an internal display, without re-rendering it.

System and method for display mirroring

A method and an apparatus that provide secure executable codes generated during run time via a trusted compiler server are described. An application can send a service request to the compiler server to request executable codes. The compiler server can determine whether the service request is permitted to be served based on a security policy imposed and the security settings associated with the service request. Availability of certain compilers can be allowed if the application is authorized according to the service request.
