Scan Barcode Off Screen

Issue: When you scan a barcode displayed on a flat-screen TV, a mobile phone, LCD or LED screens, 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.
