www.DataSymbol.com Barcode Reading Software
How most barcode scanning programs work. A barcode program periodically calls the autofocus function. This happens regardless of what is in the frame, whether the image is blurred or not. This often leads to the decoding process slowing down significantly, since the camera can start focusing again, even if the frame is of good quality. If the barcode is of poor quality, the program is not able to recognize it quickly and starts trying to focus infinitely, thus hindering the decoding process. In the new 5.60 version of our DataSymbol SDK, we have added a new feature that allows you to assess the sharpness of any part of the frame. See for yourself how it works. When a frame is not sharp (red frame of the focus area), the program detects it and implements the focusing feature. If the image is sharp, focusing does not occur. What do we have as a result? No focusing when the image is sharp, and the barcode can be decoded. Quick scanning of the barcodes that are located within the same distance without the need to focus.
