6.1.2 SELECTING A PROPER IMAGE TYPE
There are five types of image modes for you to make your target picture as vivid as possible. Depending on the
image complexity and paper quality of an original , a user may utilize these image modes to retouch a scanned
image to be as ideal as he/she prefers. Please see Figure 6-4 below and the detailed introductions of each
image mode followed.
Figure 6-4 Image Type
Each of the five image types is described as follows:
Line art
LineArt presents the image in black and white only and there are no intermediate shades of gray in
between. That means each pixel of the image is 100% black or 100% white. LineArt is the best choice of
image type if you want to scan text, pen or ink drawing. Since only 1-bit of black or white information is
required for each pixel*, the disk space required for saving lineArt image is only about 1/24 of that required
to save 24-bit true color images.

*Pixel: A combination of two words: picture and element, a pixel is a single dot on a computer display or in a
digital image.
