Quality degradation of the scan in background

Dear all,
I have a problem with my scans on MadMapper (4.0.4).
I can scan without any problem, and it creates a PNG file, in quite good quality (enough to work on it). But when it is in "Background", in my workspace, the quality is way lower. The is a lot more of "dead pixels" (PNG fils and screenshot of my Madmapper in attachment).
Is it normal ?
Do I have solutions to keep the quality of the PNG ?
Thank's a lot !

That's an aliasing issue. If you zoom in you'll see all pixels.
MadMapper sets the pixel black where the photo camera pixel does not exactly match a projector pixel. There are tricks to clean the image in photoshop, I remember I saw a youtube video showing how. We should experiment some algorithmic to fill those gaps and get a cleaner image.
