Solving Picture Problems
If you’re not satisfied with some of the pictures you get from
the PhotoPC 3100Z, you may need to adjust the camera
settings. Read the suggestions below.
Your pictures display poor image quality on the screen or
when you print them out.
◗ PhotoPC 3100Z captures images in 24-bit color
(16.7 million colors). Your pictures will not display
maximum image quality if your monitor or computer’s
video controller doesn’t support this color depth. You
may need to upgrade your system to achieve the best
possible image quality.
◗ If your pictures look better on the screen than when you
print them out, you may need to upgrade your printer.
An EPSON Stylus
 ink jet printer, for example,
provides excellent image quality. Also see your printer
manual to change your print settings, if necessary.
◗ If you used drag and drop to insert your pictures, they
may appear grainy. Try importing them into your
documents instead.
When you preview images on your computer, they look
distorted.
◗ If you are using an STB ® Velocity 128 video card and
have a screen resolution of 800 × 600 or 640 × 480, you
may notice this phenomenon. Slowing down the
acceleration on your video card may solve this problem:
Click
Start , point to Settings , click Control Panel ,
then double-click System . On the Performance tab,
click the Graphics button. Select a slower acceleration
and click OK . See your Windows documentation or
help system for more information.
The colors in your picture don’t look right.
◗ When you take pictures under certain artificial lighting
conditions, the colors may be slightly distorted. You can
adjust your camera’s white balance setting to correct the
colors while you are taking photos (see Chapter 5).
