Scanning modes

The digitized images can contain up to 4000 dpi (dots per

inch) of image information. Color is achieved with a tri-color

CCD in combination with a cold cathode fluorescent light

source. Two modes are available:

• 8-bit mode: Each dot can be represented by an 8-bit RGB

code per color, resulting in 256 levels of gray, or 16.7 million

colors. The original is scanned at 12-bits per channel, and the

results are optimized to 8-bits per channel to produce a 24-bit

RGB image.

• 12-bit mode: Each dot can be represented by a 12-bit code

per color, resulting in 4096 levels of gray or 68.7 billion RGB

colors.
