average images with IMAQ add and IMAQ divide

[Arend]

I'm having trouble averaging images I obtain from a 1409 framegrabber.

I only works for 2 images when acquiring images, either 8 or 10 bit.

According to me it should work for either 64 10 bits images or 256 8 bits images.

Does anybody see any obvious mistakes in my program?

Hi,

I haven't been able to look at your code, but are you sure it hasn't got anything to do with overflow? (values > 255)?
Easiest way (if there is no time constraint), is to use the ImageToArray function. Convert then to I32, and you are able to add as many pictures as you want.
Afterwards divide and use the ArrayToImage function.
