¡ Multi-value scanning
Function:
Usage:
03_IS430-BODY
Multi-value scanning can record 4, 6, or 8 bits of information for each dot on the
image.
The 4-bit multi-value data represents 16 different shades of gray, the 6-bit data rep-
resents 64 shades of gray, 8-bit data represents 256 different shades of gray.
Note that the multi-value scanning uses more memory and disk space. For example,
8-bit scanning needs 8 times space more than binary (1-bit) scanning of the same
scan area.
Uses multi-value scanning to scan an image with gray shading, such as a photo-
graph, to be printed or displayed on a gray scale device.
Select 4-bit, 6-bit, or 8-bit according to the gray level of your output device.
