TWAIN Dialog Box 18 Chapter IV The TWAIN interface allows you to make important adjustments before scanning. For example, you can scan in different modes: Color, B/W or Grayscale; increase or decrease the resolution (dots per inch of an image), and adjust the brightness and/or contrast. The scale can also depend on what resolution you have your display set at, and the scan resolution. Brightness and Contrast Brightness is the amount of light that is concentrated onto a document while it is being scanned. Adjust the brightness by sliding the button located between the arrows either left or right. Turn the brightness down if characters are thick and dark, and up if characters are thin. Sharpen allows you to sharpen the edges within an image by making the edges in an image more distinct. The Sharpen filter also increases contrast by making dark edges darker and surrounding light edges lighter. Sharpen More: see Sharpen. 23 Chapter IV Descreen applies filtering to images that contain moiré patterns (or herringbone).
