Calibration
Under most circumstances, calibration is performed automati-
cally at intervals when no media are inserted in the scanner. If
film has been left in the scanner for a long period of time, you
may need to remove the film and click the Calibrate button to
recalibrate the scanner.
If you are using the MA-20 (S), remove the media from the
adapter before clicking Calibrate. If you are using the SA-21/
SA-20 or SA-30, the film while automatically be ejected during
calibration and feed back into the scanner when calibration is
complete. In the case of the IA-20 (S), you will be prompted to
rewind the film before calibration begins.
Interpolation Method (LS-2000/COOLSCAN III only)
Your scanner can scan at 2,700 ppi and at any resolution below
this value that can be produced by dividing 2,700 by a whole
number (1,350 ppi, 900 ppi, 675 dpi, etc.). At other resolutions,
pixels must be calculated by computer algorithm to make up
the specified number of pixels per inch. The interpolation method
is the algorithm used in generating these extra pixels.
The following interpolation methods are available:
Method
Description
None
No interpolation is performed. Note that
this may result in the output size for the
scanned image being larger than that specified
in the Crop palette.
Bilinear
Extra pixels are generated using a bilinear
algorithm.
Neighbor
Extra pixels are generated using a “nearest
neighbor” algorithm.
