Built-in Camera
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 95) .
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.
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.
What should I do if my computer becomes unstable when it enters a power saving mode
while the built-in camera is in use?
If your computer automatically enters Sleep or Hibernate mode, change the corresponding power saving mode setting. To
change the setting, see
Using the Power Saving Modes (page 30) .
