8.3.2 Poor Quality Image
Use this chart if the image is poor quality, is completely white, or is completely black. If you get no
image at all when you attempt to capture an image with the frame grabber, use the chart that
appears in Section 8.3.1 on
page 209 .
Yes
Yes
No
Use the CCT+ to activate the factory configuration set
and then capture a few normal images.
Is the problem still present?
One of the camera’s settings was
significantly misadjusted. Review the
camera manual to make sure that you
are setting the camera correctly.
No
Use the Camera Configuration Tool Plus (CCT+) to set the camera for test image one.
Capture several images and carefully check the pixel values in each image. (Most frame
grabbers include software tools that allow you to see the individual values of each pixel
in the image and histograms that display distributions of the pixel values in the image.)
The pixel values in your captured test image should be exactly as described in
Section 6.4 on page 132 . Also, if you capture several test images, the pixel values
should be the same in all of the captured test images.
Are the test images OK?

Contact Basler technical support. The contact numbers appear on the front pages of this manual.
Before you call for support, be sure to make note of the camera settings and the frame grabber settings you are
using. You should also have a captured live image and a captured test image available. Basler technical support will
frequently request that you e-mail copies of these captured images.

Images are too
bright or too dark.
Images look noisy. Other image
problems.
Do the following:
Make sure that the lens cap has been
removed.
Check the lens aperture. If the images are
too dark, try opening the aperture. Try
closing the aperture if they are too bright.
Check the exposure time. If the images are
too dark, try increasing the exposure. Try
decreasing the exposure if they are too
bright.
Check your light source. If the images are
too dark, try increasing your light intensity.
Try decreasing the intensity if they are too
bright.
Check your gain setting. If the images are
too dark, try increasing the gain. Try
decreasing the gain if they are too bright.
Has the problem been corrected?
Do the following:
Make sure that you are using a DC light
source. Using an AC light source can make
images appear noisy.
Make sure that the camera has proper
ventilation. If the camera becomes
extremely hot, it may produce noisy images.
Check the exposure time. If you use an
extremely long exposure time, the images
can become noisy.
Check your gain setting. Using a very high
gain setting can cause noisy images.
Examine the objects that you are imaging.
Objects with characteristics such as
changing surface texture or reflectance will
produce images that appear noisy.
