Classes |--------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [CameraCaptureSession](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraCaptureSession) | A configured capture session for a[CameraDevice](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraDevice), used for capturing images from the camera or reprocessing images captured from the camera in the same session previously. | | [CameraCharacteristics](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraCharacteristics) | The properties describing a[CameraDevice](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraDevice). | | [CameraConstrainedHighSpeedCaptureSession](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraConstrainedHighSpeedCaptureSession) | A constrained high speed capture session for a[CameraDevice](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraDevice), used for capturing high speed images from the[CameraDevice](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraDevice)for high speed video recording use case. | | [CameraDevice](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraDevice) | The CameraDevice class is a representation of a single camera connected to an Android device, allowing for fine-grain control of image capture and post-processing at high frame rates. | | [CameraExtensionCharacteristics](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraExtensionCharacteristics) | Allows clients to query availability and supported resolutions of camera extensions. | | [CameraExtensionSession](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraExtensionSession) | A camera capture session that enables access to device-specific camera extensions, which often use multi-frame bursts and sophisticated post-process algorithms for image capture. | | [CameraManager](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraManager) | A system service manager for detecting, characterizing, and connecting to[CameraDevices](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraDevice). | | [CameraMetadata](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraMetadata) | The base class for camera controls and information. | | [CameraOfflineSession](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraOfflineSession) | A camera capture session that was switched to offline mode via successful call to[CameraCaptureSession.switchToOffline](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraCaptureSession#switchToOffline(kotlin.collections.MutableCollection,%20java.util.concurrent.Executor,%20android.hardware.camera2.CameraOfflineSession.CameraOfflineSessionCallback)). | | [CaptureFailure](https://developer.android.com/reference/kotlin/android/hardware/camera2/CaptureFailure) | A report of failed capture for a single image capture from the image sensor. | | [CaptureRequest](https://developer.android.com/reference/kotlin/android/hardware/camera2/CaptureRequest) | An immutable package of settings and outputs needed to capture a single image from the camera device. | | [CaptureResult](https://developer.android.com/reference/kotlin/android/hardware/camera2/CaptureResult) | The subset of the results of a single image capture from the image sensor. | | [DngCreator](https://developer.android.com/reference/kotlin/android/hardware/camera2/DngCreator) | The[DngCreator](https://developer.android.com/reference/kotlin/android/hardware/camera2/DngCreator)class provides functions to write raw pixel data as a DNG file. | | [MultiResolutionImageReader](https://developer.android.com/reference/kotlin/android/hardware/camera2/MultiResolutionImageReader) | The MultiResolutionImageReader class wraps a group of[ImageReaders](https://developer.android.com/reference/kotlin/android/media/ImageReader.html#)with the same format and different sizes, source camera Id, or camera sensor modes. | | [TotalCaptureResult](https://developer.android.com/reference/kotlin/android/hardware/camera2/TotalCaptureResult) | The total assembled results of a single image capture from the image sensor. | ## Exceptions |------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [CameraAccessException](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraAccessException) | `CameraAccessException`is thrown if a camera device could not be queried or opened by the[CameraManager](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraManager), or if the connection to an opened[CameraDevice](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraDevice)is no longer valid. |
