Acquiring and saving images
19
To adjust the numerical value of the sharpen filter parameter, use the mouse to
move the slide control to the right or left. Whether the contours of the image
appear to be sharper or softer when you apply the sharpen filter, depends on the
position of the
Sharpen filter parameter
slide control.
Increasing sharpness will accentuate edges, but also brings out more image
noise. Reducing the sharpness makes the image softer. Entering a value of 0 will
result in the sharpen filter having no effect at all.
Please note that when you use the sharpen filter you not only alter the monitor
display, but the actual image information as well. This means that when you are
planning on quantitatively evaluating your images later, you should not use the
sharpen filter. Your software provides you with commands with which you can
subsequently process an image's sharpness at any time.
The
Sharpen Filter Settings
button is only available if the sharpen filter has been
activated.

finalizing your image acquisition. The TWAIN dialog box closes. You can now
save the image as an image file.

image. Only a black image will appear in the image buffer. As an alternative, you
