# Class: Camera
|
|
||||||
|
|
||||||
[Camera](../modules/camera.md).Camera
|
|
||||||
|
|
||||||
### A powerful `<Camera>` component.
|
|
||||||
|
|
||||||
The `<Camera>` component's most important (and therefore _required_) properties are:
|
|
||||||
|
|
||||||
* `device`: Specifies the [CameraDevice](../modules/cameradevice.md) to use. Get a [CameraDevice](../modules/cameradevice.md) by using the [useCameraDevices](../modules/hooks_usecameradevices.md#usecameradevices) hook, or manually by using the [Camera.getAvailableCameraDevices](camera.camera-1.md#getavailablecameradevices) function.
|
|
||||||
* `isActive`: A boolean value that specifies whether the Camera should actively stream video frames or not. This can be compared to a Video component, where `isActive` specifies whether the video is paused or not. If you fully unmount the `<Camera>` component instead of using `isActive={false}`, the Camera will take a bit longer to start again.
|
|
||||||
|
|
||||||
**`example`**
|
|
||||||
```jsx
|
|
||||||
function App() {
|
|
||||||
const devices = useCameraDevices('wide-angle-camera')
|
|
||||||
const device = devices.back
|
|
||||||
|
|
||||||
if (device == null) return <LoadingView />
|
|
||||||
return (
|
|
||||||
<Camera
|
|
||||||
style={StyleSheet.absoluteFill}
|
|
||||||
device={device}
|
|
||||||
isActive={true}
|
|
||||||
/>
|
|
||||||
)
|
|
||||||
}
|
|
||||||
```

## Properties
|
|
||||||
|
|
||||||
### context
|
|
||||||
|
|
||||||
• **context**: *any*
|
|
||||||
|
|
||||||
If using the new style context, re-declare this in your class to be the
|
|
||||||
`React.ContextType` of your `static contextType`.
|
|
||||||
Should be used with type annotation or static contextType.
|
|
||||||
|
|
||||||
```ts
|
|
||||||
static contextType = MyContext
|
|
||||||
// For TS pre-3.7:
|
|
||||||
context!: React.ContextType<typeof MyContext>
|
|
||||||
// For TS 3.7 and above:
|
|
||||||
declare context: React.ContextType<typeof MyContext>
|
|
||||||
```

## Methods
|
|
||||||
|
|
||||||
### UNSAFE\_componentWillMount
|
|
||||||
|
|
||||||
▸ `Optional`**UNSAFE_componentWillMount**(): *void*
|
|
||||||
|
|
||||||
Called immediately before mounting occurs, and before `Component#render`.
|
|
||||||
Avoid introducing any side-effects or subscriptions in this method.
|
|
||||||
|
|
||||||
This method will not stop working in React 17.
|
|
||||||
|
|
||||||
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
|
|
||||||
prevents this from being invoked.
|
|
||||||
|
|
||||||
**`deprecated`** 16.3, use componentDidMount or the constructor instead
|
|
||||||
|
|
||||||

### UNSAFE\_componentWillReceiveProps
|
|
||||||
|
|
||||||
▸ `Optional`**UNSAFE_componentWillReceiveProps**(`nextProps`: *Readonly*<CameraFormatProps & CameraScannerPropsNever & [*CameraDeviceProps*](../modules/camera.md#cameradeviceprops) & [*CameraDynamicProps*](../modules/camera.md#cameradynamicprops) & [*CameraEventProps*](../modules/camera.md#cameraeventprops) & ViewProps\> \| *Readonly*<CameraFormatProps & *Pick*<CameraScannerPropsNever, never\> & { `onCodeScanned`: (`codes`: *Readonly*<{ `bounds`: { `height`: *number* ; `maxX`: *number* ; `maxY`: *number* ; `minX`: *number* ; `minY`: *number* ; `width`: *number* } ; `code?`: *undefined* \| *string* ; `type`: [*CodeType*](../modules/code.md#codetype) }\>[]) => *void* ; `scannableCodes`: [*CodeType*](../modules/code.md#codetype)[] } & [*CameraDeviceProps*](../modules/camera.md#cameradeviceprops) & [*CameraDynamicProps*](../modules/camera.md#cameradynamicprops) & [*CameraEventProps*](../modules/camera.md#cameraeventprops) & ViewProps\> \| *Readonly*<*Pick*<CameraFormatProps, never\> & { `colorSpace?`: *undefined* \| *hlg-bt2020* \| *p3-d65* \| *srgb* \| *yuv* ; `format?`: *undefined* \| *Readonly*<{ `autoFocusSystem`: [*AutoFocusSystem*](../modules/cameradevice.md#autofocussystem) ; `colorSpaces`: [*ColorSpace*](../modules/cameradevice.md#colorspace)[] ; `fieldOfView`: *number* ; `frameRateRanges`: *Readonly*<{ `maxFrameRate`: *number* ; `minFrameRate`: *number* }\>[] ; `isHighestPhotoQualitySupported?`: *undefined* \| *boolean* ; `maxISO`: *number* ; `maxZoom`: *number* ; `minISO`: *number* ; `photoHeight`: *number* ; `photoWidth`: *number* ; `supportsPhotoHDR`: *boolean* ; `supportsVideoHDR`: *boolean* ; `videoHeight?`: *undefined* \| *number* ; `videoStabilizationModes`: [*VideoStabilizationMode*](../modules/cameradevice.md#videostabilizationmode)[] ; `videoWidth?`: *undefined* \| *number* }\> ; `fps?`: *undefined* \| *number* ; `hdr?`: *undefined* \| *boolean* ; `lowLightBoost?`: *undefined* \| *boolean* ; `preset?`: *undefined* } & CameraScannerPropsNever & [*CameraDeviceProps*](../modules/camera.md#cameradeviceprops) & [*CameraDynamicProps*](../modules/camera.md#cameradynamicprops) & [*CameraEventProps*](../modules/camera.md#cameraeventprops) & ViewProps\> \| *Readonly*<*Pick*<CameraFormatProps, never\> & { `colorSpace?`: *undefined* \| *hlg-bt2020* \| *p3-d65* \| *srgb* \| *yuv* ; `format?`: *undefined* \| *Readonly*<{ `autoFocusSystem`: [*AutoFocusSystem*](../modules/cameradevice.md#autofocussystem) ; `colorSpaces`: [*ColorSpace*](../modules/cameradevice.md#colorspace)[] ; `fieldOfView`: *number* ; `frameRateRanges`: *Readonly*<{ `maxFrameRate`: *number* ; `minFrameRate`: *number* }\>[] ; `isHighestPhotoQualitySupported?`: *undefined* \| *boolean* ; `maxISO`: *number* ; `maxZoom`: *number* ; `minISO`: *number* ; `photoHeight`: *number* ; `photoWidth`: *number* ; `supportsPhotoHDR`: *boolean* ; `supportsVideoHDR`: *boolean* ; `videoHeight?`: *undefined* \| *number* ; `videoStabilizationModes`: [*VideoStabilizationMode*](../modules/cameradevice.md#videostabilizationmode)[] ; `videoWidth?`: *undefined* \| *number* }\> ; `fps?`: *undefined* \| *number* ; `hdr?`: *undefined* \| *boolean* ; `lowLightBoost?`: *undefined* \| *boolean* ; `preset?`: *undefined* } & *Pick*<CameraScannerPropsNever, never\> & { `onCodeScanned`: (`codes`: *Readonly*<{ `bounds`: { `height`: *number* ; `maxX`: *number* ; `maxY`: *number* ; `minX`: *number* ; `minY`: *number* ; `width`: *number* } ; `code?`: *undefined* \| *string* ; `type`: [*CodeType*](../modules/code.md#codetype) }\>[]) => *void* ; `scannableCodes`: [*CodeType*](../modules/code.md#codetype)[] } & [*CameraDeviceProps*](../modules/camera.md#cameradeviceprops) & [*CameraDynamicProps*](../modules/camera.md#cameradynamicprops) & [*CameraEventProps*](../modules/camera.md#cameraeventprops) & ViewProps\>, `nextContext`: *any*): *void*
|
|
||||||
|
|
||||||
Called when the component may be receiving new props.
|
|
||||||
React may call this even if props have not changed, so be sure to compare new and existing
|
|
||||||
props if you only want to handle changes.
|
|
||||||
|
|
||||||
Calling `Component#setState` generally does not trigger this method.
|
|
||||||
|
|
||||||
This method will not stop working in React 17.
|
|
||||||
|
|
||||||
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
|
|
||||||
prevents this from being invoked.
|
|
||||||
|
|
||||||
**`deprecated`** 16.3, use static getDerivedStateFromProps instead
|
|
||||||

React may call this even if props have not changed, so be sure to compare new and existing
|
|
||||||
props if you only want to handle changes.
|
|
||||||
|
|
||||||
Calling `Component#setState` generally does not trigger this method.
|
|
||||||
|
|
||||||
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
|
|
||||||
prevents this from being invoked.
|
|
||||||
|
|
||||||
**`deprecated`** 16.3, use static getDerivedStateFromProps instead; will stop working in React 17

|
||||||
|
|
||||||
Runs before React applies the result of `render` to the document, and
|
|
||||||
returns an object to be given to componentDidUpdate. Useful for saving
|
|
||||||
things such as scroll position before `render` causes changes to it.
|
|
||||||
|
|
||||||
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated
|
|
||||||
lifecycle events from running.

Called to determine whether the change in props and state should trigger a re-render.
|
|
||||||
|
|
||||||
`Component` always returns true.
|
|
||||||
`PureComponent` implements a shallow comparison on props and state and returns true if any
|
|
||||||
props or states have changed.
|
|
||||||
|
|
||||||
If false is returned, `Component#render`, `componentWillUpdate`
|
|

# Class: Camera
|
|
||||||
|
|
||||||
[index](../modules/index.md).Camera
|
|
||||||
|
|
||||||
### A powerful `<Camera>` component.
|
|
||||||
|
|
||||||
The `<Camera>` component's most important (and therefore _required_) properties are:
|
|
||||||
|
|
||||||
* `device`: Specifies the [CameraDevice](../modules/index.md#cameradevice) to use. Get a [CameraDevice](../modules/index.md#cameradevice) by using the [useCameraDevices](../modules/index.md#usecameradevices) hook, or manually by using the [Camera.getAvailableCameraDevices](index.camera.md#getavailablecameradevices) function.
|
|
||||||
* `isActive`: A boolean value that specifies whether the Camera should actively stream video frames or not. This can be compared to a Video component, where `isActive` specifies whether the video is paused or not. If you fully unmount the `<Camera>` component instead of using `isActive={false}`, the Camera will take a bit longer to start again.
|
|
||||||
|
|
||||||
**`example`**
|
|
||||||
```jsx
|
|
||||||
function App() {
|
|
||||||
const devices = useCameraDevices('wide-angle-camera')
|
|
||||||
const device = devices.back
|
|
||||||
|
|
||||||
if (device == null) return <LoadingView />
|
|
||||||
return (
|
|
||||||
<Camera
|
|
||||||
style={StyleSheet.absoluteFill}
|
|
||||||
device={device}
|
|
||||||
isActive={true}
|
|
||||||
/>
|
|
||||||
)
|
|
||||||
}
|
|
||||||
```

## Properties
|
|

|
|
||||||
### context
|
|
||||||
|
|
||||||
• **context**: *any*
|
|
||||||
|
|
||||||
If using the new style context, re-declare this in your class to be the
|
|
||||||
`React.ContextType` of your `static contextType`.
|
|
||||||
Should be used with type annotation or static contextType.
|
|
||||||
|
|
||||||
```ts
|
|
||||||
static contextType = MyContext
|
|
||||||
// For TS pre-3.7:
|
|
||||||
context!: React.ContextType<typeof MyContext>
|
|
||||||
// For TS 3.7 and above:
|
|
||||||
declare context: React.ContextType<typeof MyContext>
|
|
||||||
```

Avoid introducing any side-effects or subscriptions in this method.
|
|
||||||
|
|
||||||
This method will not stop working in React 17.

|

|
|
||||||
Called when the component may be receiving new props.
|
|
||||||
React may call this even if props have not changed, so be sure to compare new and existing
|
|
||||||
props if you only want to handle changes.
|
|
||||||
|
|
||||||
Calling `Component#setState` generally does not trigger this method.
|
|
||||||
|
|
||||||
This method will not stop working in React 17.
|
|

|
|
||||||
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
|
|
||||||
prevents this from being invoked.
|
|
||||||
|
|

**`deprecated`** 16.3, use static getDerivedStateFromProps instead

|
|
||||||
|
|
||||||
Called when the component may be receiving new props.
|
|
||||||
React may call this even if props have not changed, so be sure to compare new and existing
|
|
||||||
props if you only want to handle changes.
|
|
||||||
|
|
||||||
Calling `Component#setState` generally does not trigger this method.
|
|
||||||
|
|
||||||
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
|
|
||||||
prevents this from being invoked.
|
|
||||||
|
|
||||||
**`deprecated`** 16.3, use static getDerivedStateFromProps instead; will stop working in React 17

Runs before React applies the result of `render` to the document, and
|
|
||||||
returns an object to be given to componentDidUpdate. Useful for saving
|
|
||||||
things such as scroll position before `render` causes changes to it.
|
|
||||||
|
|
||||||
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated
|
|
||||||
lifecycle events from running.

Called to determine whether the change in props and state should trigger a re-render.
|
|
||||||
|
|
||||||
`Component` always returns true.
|
|
||||||
`PureComponent` implements a shallow comparison on props and state and returns true if any
|
|

props or states have changed.
|
|
||||||
|
|
||||||
If false is returned, `Component#render`, `componentWillUpdate`
|
|

|
|
||||||
Ƭ **VideoStabilizationMode**: *off* \| *standard* \| *cinematic* \| *cinematic-extended* \| *auto*
|
|
||||||
|
|
||||||
Indicates a format's supported video stabilization mode
|
|
||||||
|
|
||||||
* `"off"`: Indicates that video should not be stabilized
|
|
||||||
* `"standard"`: Indicates that video should be stabilized using the standard video stabilization algorithm introduced with iOS 5.0. Standard video stabilization has a reduced field of view. Enabling video stabilization may introduce additional latency into the video capture pipeline
|
|
||||||
* `"cinematic"`: Indicates that video should be stabilized using the cinematic stabilization algorithm for more dramatic results. Cinematic video stabilization has a reduced field of view compared to standard video stabilization. Enabling cinematic video stabilization introduces much more latency into the video capture pipeline than standard video stabilization and consumes significantly more system memory. Use narrow or identical min and max frame durations in conjunction with this mode
|
|
||||||
* `"cinematic-extended"`: Indicates that the video should be stabilized using the extended cinematic stabilization algorithm. Enabling extended cinematic stabilization introduces longer latency into the video capture pipeline compared to the AVCaptureVideoStabilizationModeCinematic and consumes more memory, but yields improved stability. It is recommended to use identical or similar min and max frame durations in conjunction with this mode (iOS 13.0+)
|
|
||||||
* `"auto"`: Indicates that the most appropriate video stabilization mode for the device and format should be chosen automatically

||||||
Indicates a format's supported video stabilization mode
|
|
||||||
|
|
||||||
* `"off"`: Indicates that video should not be stabilized
|
|
||||||
* `"standard"`: Indicates that video should be stabilized using the standard video stabilization algorithm introduced with iOS 5.0. Standard video stabilization has a reduced field of view. Enabling video stabilization may introduce additional latency into the video capture pipeline
|
|
||||||
* `"cinematic"`: Indicates that video should be stabilized using the cinematic stabilization algorithm for more dramatic results. Cinematic video stabilization has a reduced field of view compared to standard video stabilization. Enabling cinematic video stabilization introduces much more latency into the video capture pipeline than standard video stabilization and consumes significantly more system memory. Use narrow or identical min and max frame durations in conjunction with this mode
|
|
||||||
* `"cinematic-extended"`: Indicates that the video should be stabilized using the extended cinematic stabilization algorithm. Enabling extended cinematic stabilization introduces longer latency into the video capture pipeline compared to the AVCaptureVideoStabilizationModeCinematic and consumes more memory, but yields improved stability. It is recommended to use identical or similar min and max frame durations in conjunction with this mode (iOS 13.0+)
|
|
||||||
* `"auto"`: Indicates that the most appropriate video stabilization mode for the device and format should be chosen automatically

|
||||||
|
|
||||||
Compares two devices by the following criteria:
|
|
||||||
* `wide-angle-camera`s are ranked higher than others
|
|
||||||
* Devices with more physical cameras are ranked higher than ones with less. (e.g. "Triple Camera" > "Wide-Angle Camera")
|
|
||||||
|
|
||||||
> Note that this makes the `sort()` function descending, so the first element (`[0]`) is the "best" device.
|
|
||||||
|
|
||||||
**`example`**
|
|
||||||
```js
|
|
||||||
const devices = camera.devices.sort(sortDevices)
|
|
||||||
const bestDevice = devices[0]
|
|
