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.
