Access Device Camera in Unity

Question

I need to get the Android Camera parameters like focal & exposure from Unity.

I'm using the Tango AR Camera in my Project and using the Unity AndroidJavaClass I can get the Camera class, get number of cameras, and open a camera for more options. However, when I call the Camera.open() method the app camera stops showing the feed, probably since the open() method disconnect the camera from the Tango AR Camera.

Can the Camera shared/accessed both from my code only to get cam. parameters?

Thanks.

You shouldn't use the Tango API and Android Camera API together. Tango occupies the camera hardware, which means that the Camera.open would not get a handle of the camera.

To get intrinsics, you might want to go through the Tango API.

TangoCameraIntrinsics intrinsics = new TangoCameraIntrinsics();    
VideoOverlayProvider.GetIntrinsics(TangoEnums.TangoCameraId.TANGO_CAMERA_COLOR, intrinsics);

TangoARScreen is doing something similar, see here.
