What do you mean "not stable" ?

Isn't it there at every loop iteration? At every iteration the previous image will be replaced by a new one.

I mean when i play this vi , many time the display image does not show correctly (Sometime show color , sometime show grayscale, sometime show edge detection....)

Did you play my vi? if you play my vi. you will understand "not stable" that i mean.

No, I did not play your VI. I don't have a USB camera nor the USB VI's installed on my machine. Probably your camera is not able to keep up with your loop. Slow the loop down with delays or go with a firewire camera. They are much more reliable.
