I am new to using IMAQ vision, but I am comfortable with Matlab image processing tools. I would like to crop an image using IMAQ vision around a certain region that is automatically determined before in the program. I would also like to know if there is a way to crop an image in half also. I believe if one of the questions is answered then both will be. Thank you in advance.
You'll have to use the IMAQ ROIToMask function. The trickiest part is the definition of the Region of Interest (ROI descriptor)(located in the Region-of-Interest IMAQ subpalette), but by experimenting a bit, you should rapidly get the expected result. CC

If I understand correctly, you just want to extract a part of the image. Conveniently enough, the IMAQ Extract vi does that for you. Use the optional rectangle to specify the area of interest, and set the X and Y step size to 1.
