A Boolean value indicating whether the capture output currently supports automatically combining image data on a dual camera device.
- iOS 10.2–13.0Deprecated
On devices equipped with a dual camera, image fusion combines samples from both cameras to produce a higher quality image.
To capture a photo with image fusion, set the
auto property of your photo settings object. If a device does not support image fusion, setting the
auto property has no effect (that is, the resolved
dual setting will always be false).
This property supports Key-value observing.
