Troubleshooting > Built-in Camera n168 N 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. On models with Media Gallery, you cannot use another camera application that uses the built-in camera while using the gesture function of Media Gallery. 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 computer. Why is the video input from the built-in camera suspended for a few seconds? The video input may be suspended for a few seconds if: ❑ a shortcut key with the Fn key is used. ❑ the CPU load increases. This is normal and does not indicate a malfunction. 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. ❑ The area on and around the built-in camera is dirty. Clean the area. See Care and Maintenance Information (page 140).

Troubleshooting > Built-in Camera n169 N 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. This problem may occur while your computer is running on the power saving plan, which reduces the CPU performance. See Selecting a Power Plan (page 130) to check the current power plan. What should I do if movie playback shows dropped frames while my computer is running on battery power? The battery pack is running out of power. Connect your computer to an AC outlet. What should I do if captured images flicker? This problem occurs when you use the camera under fluorescent lights due to a mismatch between the lighting output frequency and the shutter speed. To reduce flicker noise, change the direction of the camera or the brightness of camera images. In some software applications, you can set an appropriate value to one of the camera properties (e.g. light source, flicker, etc.) to eliminate flicker noise.
