5.3 SELECTING A PROPER IMAGE

TYPE

Select image type through the mode from

the scanner user interface for your own purpose.

Each image type is described as follows:

Line art(Black and White)

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.

Lineart Image

*Pixel: A combination of two words: picture and element,

a pixel is a single dot on a computer display or in a

digital image.
