androidx.camera.core

The camera interface is used to control the flow of data to use cases, control the camera via the CameraControl, and publish the state of the camera via CameraInfo.

The CameraControl provides various asynchronous operations like zoom, focus and metering which affects output of all UseCases currently bound to that camera.

An interface for filtering cameras.

An interface for retrieving camera information.

An interface which can be implemented to provide the configuration for CameraX.

An interface which contains the camera exposure related information.

Extendable builders are used to add externally defined options that can be passed to the implementation being built.

Interface for analyzing images.

Listener containing callbacks for image file I/O events.

Metadata for an image.

An image proxy which has a similar interface as android.media.Image.

A interface implemented by the application to provide a Surface for Preview.

Listener that receives updates of the TransformationInfo associated with the SurfaceRequest.

An interface which contains the zoom related information from a camera.

The aspect ratio of the use case.

A set of requirements and priorities used to select a camera or return a filtered set of cameras.

A configuration for adding implementation and user-specific behavior to CameraX.

A MeteringPointFactory that can convert a View (x, y) into a MeteringPoint which can then be used to construct a FocusMeteringAction to start a focus and metering action.

A configuration used to trigger a focus and/or metering action.

Result of the CameraControl#startFocusAndMetering(FocusMeteringAction).

A use case providing CPU accessible images for an app to perform image analysis on.

A use case for taking a picture.

A is used to specify a region which can then be converted to sensor coordinate system for focus and metering purpose.

A factory to create a MeteringPoint.

A use case that provides a camera preview stream for displaying on-screen.

A MeteringPointFactory that can create MeteringPoint by surface oriented x, y on an area defined by (0, 0) - (width, height).

A completable, single-use request of a Surface.

The camera flash torch state.

The use case which all other use cases are built on top of.

Represents a collection of UseCase.

The field of view of one or many UseCases.

An exception thrown when unable to retrieve information about a camera.

CameraUnavailableException is thrown when a camera device could not be queried or opened or if the connection to an opened camera device is no longer valid.

An exception thrown to indicate an error has occurred during image capture or while saving the captured image.

InitializationException is thrown when a failure occurs during an initialization process.

Denotes that the annotated method uses an experimental API that configures CameraX to limit the available cameras applications can use in order to optimize the initialization latency.

Denotes that the annotated method uses an experimental API that customizes camera filters to select a specific camera.

Denotes that the annotated method uses an experimental API that swaps the default threading implementation with a user-defined threading implementation.

Denotes that the annotated method uses the experimental ExposureCompensation APIs that can control the exposure compensation of the camera.

Denotes that the annotated method uses the experimental ImageProxy#getImage() method.

Denotes that the annotated method uses the experimental method CameraXConfig.Builder#setMinimumLoggingLevel(int) for specifying the minimum logging level to use inside CameraX.

Denotes that the annotated classes and methods uses the experimental feature which provides a grouping mechanism for UseCases.
