Built-in Camera
Why does the viewfinder show no images or poor-quality images?
❑ The built-in camera cannot be shared by more than one software application. Exit the current application before launching
another.
❑ The viewfinder may show some noise, for example horizontal streaks, if you view a rapid-moving object. This is normal
and does not indicate a malfunction.
❑ If the problem persists, restart your computer.
Why are captured images poor in quality?
❑ The images captured under the fluorescent light may show reflections of light.
❑ A dark portion in captured images may appear as a noise.
❑ If the lens protection cover is dirty, you cannot take a clear shot. Clean the cover. See Handling the Built-in Camera
(page 147) .
What should I do if captured images contain dropped frames and audio interruptions?
❑ The effect settings on your software application may cause dropped frames. See the help file included with your software
application for more information.
❑ There may be more software applications running than your computer can handle. Exit the applications that you are not
currently using.
❑ The power management function of your computer may be active. Check the CPU performance.
