What should I do if captured images flicker?
This problem occurs when you use the built-in camera under fluorescent lights and is due to
a mismatch between the lighting output frequency and the shutter speed.
To reduce flicker noise, change the direction of your VAIO computer so that you can adjust
the direction of the built-in camera. Some apps offer adjustable parameters, such as
brightness or power frequencies, to eliminate flicker noise.
What should I do if captured images contain dropped frames and audio interruptions?
The effect settings on your app may cause dropped frames. Refer to the help file included
with the app for more information.
There may be more app running than your VAIO computer can handle. Exit the apps that
you are not currently using.
This problem may occur while your VAIO computer is running on the power saving plan,
which reduces the CPU performance. See
to check the current power
plan.
What should I do if the touch screen does not work correctly? (Touch screen equipped models)
Turn off your VAIO computer, and then turn it on again.
Electromagnetic waves may cause the touch screen to work incorrectly. Try these
suggestions.
Move your VAIO computer away from a fluorescent light or a motor that emits electromagnetic waves.
Connect the AC adapter directly to an AC outlet or use other outlets if you are using a power strip.
Remove any USB device or cable connected to your VAIO computer, if any.
If your AC adapter has a 3-pin plug, make sure it is properly grounded.
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.
