Issue:
When you scan a barcode from a screen on a monitor, a TV or a mobile phone, the image contains roughly parallel dark and light bands superimposed, called the moiré pattern. The interfering pattern makes decoding the barcode very challenging.
Solution:
Dynamsoft Barcode Reader SDK provides an image processing step to remove the moiré texture and would quickly decode the barcode.
