Scan Source

not have to specify this menu. MyScan can automatically detect the scanner
type, and displays the type in this box.

Scan Mode

This menu specifies the mode that the image is to be scanned in.
The following pictures show some examples of the scan mode:
Gray 256 scales
True Color RGB*
Specifies 24 bit true color. In this scan mode, your scanner captures 24 bits
of color image information for every dot (pixel) in your resulting scanned
image. Therefore over 16 million colors are possible.
This image type uses the same color synthesis scheme used in computer
monitors and television. RGB simply stands for Red-Green-Blue; these are
the additive primary colors. Additive here refers to the addition, or mixing,
of light of different colors: mixing equal proportions of fully saturated red,
green, and blue light produces white light. This is the way that your color
television or color monitor produces white. Disk space required for saving
24-bit true color image is considerable. For instance, an A4-size 300-dpi true
color image may require 24 Megabytes (MB) of storage space.
256 Colors*
In this mode, only 256 colors are used to show the scanned color image. If
color is necessary, but high quality is not desired, choose this mode. Disk
space required is approximately 1/3 of that required to save 24-bit true
color images.
* These modes are available on SF4500C only.
