Hello, I am trying to use a high speed machine vision camera (AVT guppy PRO F503C) to analyze touch screen LCD user interface modules for pixel defects, foreign particles, scratches, etc... However, this process is hampered by a dark line of pixels which tracks down the screen continously during image acquistion (both grab and continous grab). I have had a little success adjusting the camera shutter value to minimize the visibility of this line, however, this has proved to be relatively inconsistent as the shutter value seems to differ from unit to unit. I am wondering if anyone has ever run into this issue and if there is any corrective action to eliminate or minimize the effects of this line (lighting, camera settings, etc..). Here is an image: Thanks, Chase Fearing Test Engineer Subzero / Wolf

Oh! I didn;t know I could do that! Here it is in 2010 format.

I don't know how you did that... awesome.

I have been having nightmares about this line ruining all my analysis', you saved me a lot of headaches, I deeply appreciate it.
