I hava a problem that I have not been able to solve. I am processing a couple of images from an AVI file; I want to substract Image A from Image B. The output is an I16 bit image. The result looks good but I would like to improve it by adjusting the image contrast and/or brightnes before saving it. The problem is that the IMAQ BCGLookup VI only takes 8 bit images. My VI is running but when I change the values of the BCGLookup VI (Brighness, contrast or Gamma) my output image does not change.
Unfortunately, IMAQ BCG Lookup only supports 8-bit images at this time. What you can do is compute your owen user lookup table and call IMAQ User Lookup 2, or IMAQ MathLookup, which both work on 16-bit images.
