Why does the viewfinder show no images or poor-quality images?

• Some camera software may not work correctly when another camera software is running. Exit the current software before starting another.

• You may not be able to use another camera software 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.
