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. 
 
Images look noisy 
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 extremly long exposure time, the images 
can become noisy. 
Check gain settings. Using a very low or 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. 
Bits that do not change value 
If data bits seem to be stuck or do not change, check that the camera is not 
saturated by preventing light from entering. Run test pattern to verify camera 
operation insert. Check all cable connections, especially right at the connector; 
poor connections or broken wires will cause randomly changing bits or stuck bits.
