intensity

[calpe3003]

I am looking for examples or help on how to write a labview VI to produce an intensity histogram from a live/continuous image that I can manually scale/adjust to increase or decrease brightness.

You can use something like this

Thank you for the reply.... Is it possible to add this function to vision assistant?  vision assistant automatically identifies my camera but I am not sure how to do it with the imaq icons.. I was also hoping to be able to drag the lines on the actual histogram to select the intensity peak.

"I was also hoping to be able to drag the lines on the actual histogram to select the intensity peak."

This can be done using the "IMAQ Select Line" VI and then the "Light Intensity Histogram" VI (I can't be sure if these names are right, I'm not at my LabVIEW PC right now.

I am not very clear abt your question. Can you explain briefly?

I am new to labview and I am trying to write a vi to work with an IR camera I have.  I attached what I have so far in the previous post.  I am able to get an image but I am not sure what or how to wire up next to get a histogram graph that I can move two lines on it in order to select intensity peaks to adjust my image.

thanks
