Can I screencapture just the black(dark) area?

[KnowNothing]

I been using _ScreenCapture_Capture to get an image on the screen but some times there are random defects (normally light white dots) in the background. Is there a way where I can take a screecapture of just the dark (black) pixels?

I use this code:

#include <ScreenCapture.au3>
For $INDEX = 1 To 10
_ScreenCapture_Capture(@ScriptDir & "\File" & $INDEX & ".JPG")
Sleep(1000)
Next

And all images is ok, _ScreenCapture_Capture work fine. Can you post your script to more help?

Sorry Andreik but that didn't help. I already have it _ScreenCapture_Capture'ing fine but it still has the random white dots (in the background of the image) that I want to get rid of.

Posting my script wound be pointless. Everything works fine but the white random dots in the background of the _ScreenCapture_Capture'ed image.

If _ScreenCapture_Capture cant just do the darker (black) pixels Can I use something like PixelChecksum on just the back (darker) pixels?

Still wondering about this.
