40 * @defgroup LibargusAPI Libargus Camera API
41 *
42 * Libargus is an API for acquiring images and associated metadata from cameras.
43 * The fundamental libargus operation is a capture:
44 * acquiring an image from a sensor and processing it into a final output image.
45 *
46 * Currently, libargus is supported on Android and L4T on NVIDIA Tegra TX1-based platforms.
47 *
48 * Libargus is designed to address a number of fundamental requirements:
49 *
50 * - Support for a wide variety of use cases (traditional photography, computational photography,
51 * video, computer vision, and other application areas.)
52 * To this end, libargus is a frame-based API; every capture is triggered by an explicit request that
53 * specifies exactly how the capture is to be performed.
54 *
55 * - Support for multiple platforms, including L4T and Android.
56 *
57 * - Efficient and simple integration into applications and larger frameworks. In support of this,
58 * libargus delivers images with EGLStreams, which are directly supported by other system components
59 * such as OpenGL and Cuda, and which require no buffer copies during delivery to the consumer.
60 *
61 * - Expansive metadata along with each output image.
62 *
63 * - Support for multiple sensors, including both separate control over independent sensors and
64 * access to synchronized multi-sensor configurations. (The latter are unsupported in the current
65 * release. When support is added, it will be available on only some NVIDIA platforms.)
66 *
67 * - Version stability and extensibility, which are provided by unchanging virtual interfaces and
68 * the ability for vendors to add specialized extension interfaces.
69 *
70 * Libargus provides functionality in a number of different areas:
71 *
72 * - Captures with a wide variety of settings.
73 *
74 * - Optional autocontrol (such as auto-exposure and auto-white-balance.)
75 *
76 * - Libraries that consume the EGLStream outputs in different ways; for example, jpeg encoding or
77 * direct application access to the images.
78 *
79 * - Metadata delivery via both libargus events and EGLStream metadata.
80 *
81 * - Image post-processing such as noise reduction and edge sharpening.
82 *
83 * - Notification of errors, image acquisition start, and other events via synchronous event queues.
84 *
85 * Functionality not provided by libargus:
86 *
87 * - Auto-focus. (Planned to be added in a later release.)
88 *
89 * - Reprocessing of YUV images (such as that required by Android’s Zero Shutter Lag feature.)
90 *
91 * - Reprocessing of Bayer (raw) images. (Planned to be added in a later release.)
92 *
93 * - Output of Bayer (raw) images. (Planned to be added in a later release.)
94 *
95 * @defgroup ArgusObjects Objects and Interfaces
96 * This module provides a list of libargus objects and the interfaces that they support.
97 * Children of objects in this list describe either child InterfaceProviders provided by
98 * the object or specialized types of the object (ie. Event types).
99 * @ingroup LibargusAPI
100 *
101 * @defgroup ArgusExtensions Extensions
102 * This module provides a list of extensions currently available for libargus.
