I need to write an array of 1 double precision number and 2 integers to a text file. I used the flatten to text but I get the file like this. @$ěHĚjŻ˛@8 @‰Č @$öOU#ĐT@< @‰Č @

Turns out instead of delaying, I should have taken more pictures because the camera needed time to adjust to the new exposure. Putting it in a while loop for a few iterations and using the last image solved this. Thanks for your help Cheers

Oh ok. Thanks I didn't know that. This is a snippet of one. Individually they work fine but again it's the same thing with same random errors.

No it doesn't provide allow to change it to VI . I would like to take the pictures with as little delay as possible. I just put 2 seconds to try it. I tried what you said but it didn't work. And everytime it is a random error: I have attached the errors here In Error1, the picture is just white. No image. In Error2, the one with the lowest exposure has the brightest image. Any ideas?

I need to take three pictures with different exposure values. I used vision acquisition for this. I tried using the finite acquisition but I could not find a way to set a different exposure value for different pictures. I used the single acquisition 3 times in a flat sequence with 2 seconds of gap. When I take a test picture with vision acquisition it looks fine but when I run it in the program, they are not at all the same. Sometimes two pictures are the same, sometimes it is just white and sometimes the higher exposure value is brighter than the lower one. Help please

Oh okay thank you. I coded the VI according to the formula. Thanks so much

Ignore the previous comment. I figured that one out, but when I check the values of L with that here http://www.easyrgb.com/index.php?X=CALC#Result . They dont match.

From a jpg image I need to extract pixel by pixel the R G and B values. Can someone help me with this? Also is it possible to extract exposure values from a jpeg image?

Hello Greg Sorry again but in this one does the L out a out and b out what are they doing? are they storing the image somewhere. usually when I right click and click on help they give a description but there was nothing on this one. It does the work fine though when I connect it to an image display. Is there a way to get pixel by pixel value of luminance and store it in a text file?

How do I get the camera Input I/O I copied this from an example but where is this in the functions palette. And how do I add a zoom out to the display? Start1.vi

Oh okay. Thanks a lot

Thank you so much. Can you recommend me a good place to find basic tutorials for vision. I have just started using this 3 days ago for my and I couldn´t figure out how to modify this for my program. I need to automatically take pictures every 10 minutes with a user defined exposure and convert them from RGB to LAB. Can you please help me out with this?

or could you send be the code/vi if you ahve it?
