Camera Image has different FOV than (little bit Zoomed in) what we see on screen.

Here is my question.
The camera image we get from TryAcquireLatestCpuImage(out XRCpuImage image ) has a wider field of view than what we actually see on the phone screen. They are a little zoomed out. I want to get the exact image of what we really on the screen exactly like the screenshot. Can Anyone help me?

You can do the following steps to see what I am trying to get.

  • Start a New AR project (Do nothing, leave it as default)
  • Start the app and take a screenshot.
  • Do not move the phone and open the camera and take a photo at the same place.
  • Compare two photos and you will see the screenshot from the AR app(what we actually see when we start the AR app) is a little bit zoomed in!
  • TryAcquireLatestCpuImage(out XRCpuImage image ) give me the one same with photo taken by phone’s default camera app

I don’t know why it is zoomed in but I want the Image that we actually see on the AR app screen. Please Help me! Thank you in advance.
