A method of providing environmental information to an electronic device includes, at the electronic device, receiving ambient light from a surrounding environment of the electronic device with one or more camera sensors in data communication with a processor and capturing a raw pattern with the camera sensor, wherein the raw pattern includes light intensity information and light spectrum information. The method further includes deriving at least one ambient light value from the light intensity information and light spectrum information and providing the ambient light value to the processor of the electronic device.

Systems and methods for providing human interface device information via a camera sensor

Described are examples for providing stream augmenting components. A stream augmenting component having an augmentation function indicating a plurality of interfaces to one or more devices and an output stream can be initialized. At least a portion of the plurality of interfaces for the one or more devices can be accessed to at least one of obtain stream output from the one or more devices or control the one or more devices. A plurality of stream outputs from the one or more devices can be virtualized to the output stream at least in part by modifying or correlating data received over the plurality of stream outputs. The stream augmenting component can output the output stream to one or more other stream augmenting components or applications via at least another portion of the one or more interfaces.

Pluggable components for augmenting device streams

In one aspect, a request is sent to a device for a device descriptor that describes custom interfaces. The custom interfaces may be expressed according to a defined data structure. The device descriptor that describes the custom interfaces is received at a gateway. An interface agnostic application is executed to translate the device descriptor to the custom interfaces for consumption of the data described by the custom interfaces.

Self-describing interfaces for communication with gateways

Described are examples for obtaining data from a single stream output. An indication of requested data from multiple stream sources can be received from an application. A single stream output including one or more output frames can be received from a stream server where at least one output frame includes at least data from each of the multiple stream sources. The requested data can be extracted from the single stream output and provided to the application.

Reading multiplexed device streams

The disclosed techniques enable a software program to communicate with a peripheral device (e.g., a sensor), via a low-level communication protocol such as the IC protocol, even though the software program does not include lower-level code configured to implement a sequence of operations defined for the low-level communication protocol. The techniques determine that the software program includes a high-level operation that instructs for communications to be conducted with the peripheral device. The high-level operation is associated with a separately stored configuration file that includes the lower-level code configured to implement the sequence of operations enabling the communications to be conducted with the peripheral device via the low-level communication protocol. The techniques then execute the lower-level code included in the configuration file and return information, to the software program, indicating that the communications with the peripheral device have been conducted via the low-level communication protocol.

Declarative transactional communications with a peripheral device via a low-power bus

A computing device includes one or more camera systems, each camera system including software and/or hardware to provide various different camera-related capabilities. The camera system maintains one or more profiles, each profile identifying different capabilities of the camera system that the computing device is configured to use concurrently. The one or more profiles are provided to a program on the computing device, allowing the program to know which capabilities the computing device is configured to use concurrently. If a profile provided by the camera system indicates that the computing device is configured to use certain capabilities concurrently (e.g., capturing images and recording video at certain resolutions), then the program allows a user to select options for using those capabilities concurrently. However, if no such profile exists, the program does not allow a user to select options for using those capabilities concurrently.

Profiles identifying camera capabilities

Described are examples for securing stream data received from a stream source. A secure mode can be enabled, based on a request from an application, for storing the stream data captured from the stream source in a secured buffer. The secured buffer can be allocated in a secure memory based at least in part on enabling the secure mode. A secured buffer identifier of the secured buffer can be provided to a driver of a device providing the stream source for storing the stream data captured from the stream source in the secured buffer. The secured buffer identifier of the secured buffer can also be provided to the application for accessing the stream data stored in the secured buffer.

Securing stream buffers

Described are examples for providing stream augmenting components. A stream augmenting component having an augmentation function indicating a plurality of interfaces to one or more devices and an output stream can be initialized. One or more functions for the one or more devices to at least one of obtain stream output from the one or more devices or control the one or more devices can be accessed. A plurality of stream outputs from the one or more devices can be virtualized to the output stream at least in part by modifying or correlating data received over the plurality of stream outputs. The output stream can be output to one or more other stream augmenting components or applications.

Techniques for arbitrating control access to a shared resource among multiple client applications concurrently consuming a shared data stream associated with the shared resource are described. A server component instantiates a shared resource component representing the shared resource and associated shared data stream. The server component publishes a shared resource interface that provides central interface for the multiple client applications to access the shared resource and associated shared data stream. Each client application may access the shared resource in either control mode or shared mode to consume the shared data stream. In control mode, the client application has read-write access to control parameters representing a configuration of the shared resource that are usable to modify aspects of the shared data stream. In shared mode, the client application has read-only access to the control parameters.

Arbitrating control access to a shared resource across multiple consumers

Memory descriptor list caching and pipeline processing techniques are described. In one or more examples, a method is configured to increase efficiency of buffer usage within a pipeline of a computing device. The method includes creation of a buffer in memory of the computing device and caching of a memory descriptor list by the computing device that describes the buffer in a buffer information cache and has associated therewith a handle that acts as a lookup to the memory descriptor list. The method also includes passing the handle through the pipeline of the computing device for processing of data within the buffer by one or more stages of the pipeline such that access to the data is obtained by the one or more stages by using the handle as the lookup as part of a call to obtain the memory descriptor list for the buffer from the buffer information cache.

Memory descriptor list caching and pipeline processing

Methods and devices for monitoring camera resource activities may include receiving a camera resource request from an application that identifies at least one camera resource being requested for use by the application. The methods and devices may include determining whether the camera resource is available for use by checking a state of the camera resource using a camera resource log that provides the state of the camera resource. The methods and devices may include granting access to the camera resource when the state of the camera resource is available for use and updating the state of the camera resource when access is granted to the camera resource. The methods and devices may include updating the camera resource log when access is granted to the camera resource with an application identification (ID) for the application using the camera resource and the state of the camera resource.

Camera usage notification

Described are examples for allocating buffers for multiple components. A stream server can provide an interface to a centralized memory allocator for allocating at least one buffer in a memory to each of the multiple components. The stream server can initialize an instance of the centralized memory allocator based at least in part on a request received from a component of the multiple components via the interface. The stream server can allocate, via the instance of the centralized memory allocator, the at least one buffer for the component in the memory. The stream server can receive, via the instance of the centralized memory allocator, data for storing in the at least one buffer. The stream server can modify the data to generate modified data stored in the at least one buffer.

Centralized memory management for multiple device streams

Methods and devices for allocating memory for use with a camera resources may include receiving camera resource requests from application plurality of applications to use a camera resource. The methods and devices may include determining a memory type to allocate to the applications for the camera resource based on the camera resource request and compatibility information of the camera resource. The methods and devices may include determining a buffer and a buffer type to provide each of the applications based on an access mode of the camera resource, wherein the buffer type comprises one or more of a shared type, a copy type, and a secure type. The methods and devices may include providing the application access to the buffer based on the determination.

Memory allocation type for media buffer

Described are examples for outputting stream data from a plurality of stream sources. A first data stream output for a first stream source and a second data stream output for a second stream source can be received. First data of the first data stream output can be correlated, in time, with second data of the second data stream output. One or more output frames can be output including the first data and the second data as correlated in time.
