About Software

  1. With USB Video Class (UVC) protocol, data communication between the software and the scanner is allowed, including real-time reading of images and videos collected by the device controlling the device to take pictures and adjusting image parameters.
  2. The self-developed built-in algorithm module for image processing allows for curved page flattening and tilt adjustment based on laser lines. The software is also able to purify the background of a scanned document and allows for smart tilt adjustment, cropping, and finger recognition and clearing.
  3. The software adopts self-developed algorithms for changing image color modes.
  4. The software can generate PDF and TIFF files. With the OCR function, it can convert image files into Word, PDF, Excel, and TXT files for editing.
  5. The functions of different devices are different, which are subject to the actual functions of the purchased device.
