CHAPTER 2 FUNCTIONS & OPERATION
b. Smoothing
method
The image resolution conversion by
averaging is called “smoothing.”
Smoothing metohd conversion enables the
data to be smoothly transformed much better
than that by thinning-out method, resulting in
reducing the occurrence of Moire patterns.
Smoothing is especially usefull for low-resolution
photographs, but the time required for the
processing is longer than that for thinning-out.
Smoothing is not performed in binary mode
since Moire patterns are not usually a problem.
For grayscale mode, smoothing is always
performed because the number of scanned
documents is not decreased even by smoothing.
For color mode, Smoothing can be selected
by the user. When the optical resolution of the
reading unit is 600 dpi (or 300 dpi), smoothing to
600 dpi (or 300 dpi) is not carried out.
When the resolution is set to 600 or 400 dpi
on the personal computer, the reading unit reads
the documents at 600 dpi. When 300 dpi or less
is selected, the unit reads the documents at 300
dpi. Subsequently, the data of 600 dpi (or 300
dpi) resolution are calculated according to the
selected resolution. The calculation is as follows.
•
The reading unit reads the document at 600 or
300 dpi.
A B C D E F · · ·
•
The data are calculated according to the
selected resolution. An example of conversion
from 300 dpi to 150 dpi is as follows:
(A+B)/2 (C+D)/2 (E+F)/2 · · ·
