# isVirtualDeviceFusionSupported

A Boolean value that indicates whether the device supports virtual device image fusion.

## Declaration

```swift
var isVirtualDeviceFusionSupported: Bool { get }
```

## Discussion

Discussion When using a virtual capture device, the system can fuse the images from its constituent cameras to improve image quality. If the current configuration doesn’t support virtual device fusion, your capture requests always resolve isVirtualDeviceFusionEnabled to false. This property is key-value observable.
