Image Updation Issue in Image Display Pallete in LabVIEW

[Prakash_Mahar]

Hi,
One of my Vision application, I am using multi-loop architecture where two loops are sharing data by local variable. Data is an array of three images, which are getting updated within 300 ms, and getting shifted in a circular Queue.
 We found a discrepancy of image palette update after a long run of application. Please suggest? Is there any issue with Image palette of LabVIEW? I am using LabVIEW 2009. 

Awaiting for your response.

Could you explain what kind of "discrepancy" you are seeing? That's a very generic term!

 You talk about "image" and sometimes "palette". What exactly updates incorrectly and how?

How long is a "long run". Seconds? Minutes? hours? days? months?

How are you "shifting images in a circular queue"? Are you simply toggling between different images or is there also a shift involved?

If you look at the task manager when running the program, how is memory use over time? (constant, increasing, etc)

Maybe you should show us a simplified example of your code.

Hi altenbach,

thanks for your immediate response.

Following are the details...

1. Descripency : Only Last Image was showing there in Image pallete. No new image update even camera capturing is happening.

2. Image Pallete mean to say: Labview Image display control

3. Image not updation problem occured once After 8 to 10 hours, but not all the time.

4. Please check the code schemetic

5. There is no memory leak
