| Filters help you improve your scans by allowing you to sharpen images as well as remove excessive dots and distortion.
|
|
|
| The following options are available from the drop-down list:
|
| · | None-- Applies no filter in the scanned image.
|
| · | Average-- Determines the medium depth of an image and averages adjacent pixels to make images appear softer.
|
| · | Blur-- Dulls the edges within an image and decreases the contrast by making dark edges lighter and light edges darker.
|
| · | Blur More-- Adds additional blurring.
|
| · | 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-- Adds additional sharpening.
|
| · | Unsharpen-- Sharpens the edges in an image to remove the blurriness.
|
|
|
| This setting is not available when Black & White is selected as Scan Mode.
