2. 13 ICE4 Advanced (Digital-ICE quad Advanced)
(
Host processing
)
"ICE4 Advanced" is generic name of Digital-ICE, Digital-ROC, Digital-GEM, and Revelation.
・
Digital-ICE
:
Detect defects (such as damages, dusts, dirt, etc), and restore the image data
that was deteriorated by these defects. Scanning is performed by visible
light of RGB and infrared light, then by getting the information on defects
from the infrared images, RGB image is restored based on such information.
This is available for Kodachrome but depending on images, slight blurs occur in
some cases.
・
Digital-ROC
:
Correct the color deterioration of films and color seepage
・
Digital-GEM
:
Control and smooth graininess of films.
・
Revelation
:
Change contrast per area, and optimize the dynamic range to get close to physical
appearance.
This is used to describe the details under the following conditions: against light;
insufficient light volume of speedlight; overexposure
2. 14 Resolution and resizing process
Maximum (optical) resolution : 4000dpi
The body (scanner) can perform pixel-skipping scanning in both main and sub scanning directions.
Pixel skipping Pitch:
1
~
1
/
44
(
corresponding to 4000dpi
~
90dpi
)
However, the scanner does not perform pixel skipping regarding odd-number Pitch except the
full Pitch.
The final scan is performed with relatively higher resolution than the resolution of the final output
image, and the driver software processes the averaging.

2.15 Thumbnail scan
・
SA-21, SA-30
The body (scanner) fixes the scan block unit, and the inner motor of SA feeds films to scan
images.
Resolution:
97dpi (Pitch 41
)
Averaging: ON (8-pixel average in the main scanning direction)
AF position: is set when outputting thumbnail or set to the latest AF address in the past (192
address when AF is not performed)
Thumbnail can be automatically performed by detecting the insertion of films.
