Why does the viewfinder show no images or poor-quality images?
Some camera apps may not work correctly when another camera app is running. Exit the current app before starting
another.
You may not be able to use another camera app that uses the built-in camera while using the gesture function.
The viewfinder may show some noise, for example horizontal streaks, when you are viewing a rapid-moving object.
This is normal and does not indicate a malfunction.
If the problem persists, restart your VAIO computer.
