Interface: CameraDevice

Represents a camera device discovered by the Camera.getAvailableCameraDevices() function

Properties​

formats​

• formats: CameraDeviceFormat[]

All available formats for this camera device. Use this to find the best format for your use case and set it to the Camera's Camera's .format property.

See the Camera Formats documentation for more information about Camera Formats.

Defined in​

CameraDevice.ts:203

hardwareLevel​

• hardwareLevel: "legacy" | "limited" | "full"

The hardware level of the Camera.

  • On Android, some older devices are running at a legacy or limited level which means they are running in a backwards compatible mode.
  • On iOS, all devices are full.

Defined in​

CameraDevice.ts:223

hasFlash​

• hasFlash: boolean

Specifies whether this camera supports enabling flash for photo capture.

Defined in​

CameraDevice.ts:149

hasTorch​

• hasTorch: boolean

Specifies whether this camera supports continuously enabling the flash to act like a torch (flash with video capture)

Defined in​

CameraDevice.ts:153

id​

• id: string

The native ID of the camera device instance.

Defined in​

CameraDevice.ts:122

isMultiCam​

• isMultiCam: boolean

A property indicating whether the device is a virtual multi-camera consisting of multiple combined physical cameras.

Examples:

  • The Dual Camera, which supports seamlessly switching between a wide and telephoto camera while zooming and generating depth data from the disparities between the different points of view of the physical cameras.
  • The TrueDepth Camera, which generates depth data from disparities between a YUV camera and an Infrared camera pointed in the same direction.

Defined in​

CameraDevice.ts:165

maxExposure​

• maxExposure: number

The maximum Exposure-Bias value this format supports. When setting the exposure to this value, the image is almost completely bright (over-exposed).

Defined in​

CameraDevice.ts:197

maxZoom​

• maxZoom: number

Maximum available zoom factor (e.g. 128)

Defined in​

CameraDevice.ts:173

minExposure​

• minExposure: number

The minimum Exposure-Bias value this format supports. When setting the exposure to this value, the image is almost completely dark (under-exposed).

Defined in​

CameraDevice.ts:193

minFocusDistance​

• minFocusDistance: number

The minimum distance this device can properly focus to (in centimeters/cm) or 0 if unknown.

Defined in​

CameraDevice.ts:157

minZoom​

• minZoom: number

Minimum available zoom factor (e.g. 1)

Defined in​

CameraDevice.ts:169

name​

• name: string

A friendly localized name describing the camera.

Defined in​

CameraDevice.ts:145

neutralZoom​

• neutralZoom: number

The zoom factor where the camera is "neutral".

  • For single-physical cameras this property is always 1.0.
  • For multi cameras this property is a value between minZoom and maxZoom, where the camera is in wide-angle mode and hasn't switched to the ultra-wide-angle ("fish-eye") or telephoto camera yet.

Use this value as an initial value for the zoom property if you implement custom zoom. (e.g. reanimated shared value should be initially set to this value)

Example

const device = ...

const zoom = useSharedValue(device.neutralZoom) // <-- initial value so it doesn't start at ultra-wide
const cameraProps = useAnimatedProps(() => ({
  zoom: zoom.value
}))

Defined in​

CameraDevice.ts:189

physicalDevices​

• physicalDevices: PhysicalCameraDeviceType[]

The physical devices this CameraDevice consists of.

  • If this camera device is a logical camera (combination of multiple physical cameras, e.g. "Triple Camera"), there are multiple cameras in this array.
  • If this camera device is a physical camera (e.g. "wide-angle-camera"), there is only a single element in this array.

You can check if the camera is a logical multi-camera by using the isMultiCam property.

Defined in​

CameraDevice.ts:131

position​

• position: CameraPosition

Specifies the physical position of this camera.

  • back: The Camera Device is located on the back of the phone. These devices can be used for capturing what's in front of the user.
  • front: The Camera Device is located on the front of the phone. These devices can be used for selfies or FaceTime.
  • external: The Camera Device is an external device. These devices can be either:

Defined in​

CameraDevice.ts:141

sensorOrientation​

• sensorOrientation: Orientation

Represents the sensor's orientation relative to the phone. For most phones this will be landscape, as Camera sensors are usually always rotated by 90 degrees (i.e. width and height are flipped).

Defined in​

CameraDevice.ts:228

supportsFocus​

• supportsFocus: boolean

Specifies whether this device supports focusing (Camera.focus(...))

Defined in​

CameraDevice.ts:217

supportsLowLightBoost​

• supportsLowLightBoost: boolean

Whether this camera device supports low light boost.

Defined in​

CameraDevice.ts:207

supportsRawCapture​

• supportsRawCapture: boolean

Whether this camera supports taking photos in RAW format
