Resolution
The correct resolution will reproduce a clear image with good
details. The resolution is measured in dots per inch (dpi).
Note
An A4/Letter size color image scanned at 300 dpi at True Color
mode consumes approximately 25 MB of disk space. A higher
resolution (usually means over 600 dpi) is only recommended
when you need to scan a small area in True Color mode.
Adjusting the brightness and contrast
1. Brightness
Adjusts the lightness or darkness of an image. The higher the
value, the brighter the image.
2. Contrast
Adjusts the range between the darkest and the lightest shades
in the image. The higher the contrast, the larger the grayscale.
Enlarging previewed image (zoom)
Enlarge your previewed image to the maximum of the preview
window.
Note
This function only enlarges your preview image. This does not
enlarge the actual image.

The invert command reverses the brightness and the color in
the image. For color images, each pixel will be changed into its
complementary color when inverted.
