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, 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 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 Built-in Camera
(page 90) .
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.
