How to sharpen text and remove shadows?

To sharpen the text and remove the shadows, please follow the steps below:

  1. Start scanning. After proceeding to the next step, the page processing screen will appear.
  2. There will be two images on the screen: 
    The top image is the detected document boundary with 4 corners. (Orange border box)
    The bottom image is the cropped and enhanced result that will be eventually saved as your document.
  3. There are three automatic modes for you to choose from: "Photo", "Color", and "B & W" (Black and White).
    You can manually select another mode if it doesn't look right. (It will result in the bottom image.)
  4. To sharpen text and remove shadows, you must select the "Color" mode or the"B & W" mode.
