Interpolation: PowerColor provides the following interpolation modes:
– Bi-Cubic: weighted average of a region of pixels around the target pixel
(default mode). This type of interpolation provides high quality for con-
tinuous tone images when scaled to a resolution higher than that of the
scanner.
– Bi-linear: weighted average of adjacent pixels. This setting provides high
quality with better performance than Bi-Cubic, but may cause unwant-
ed patterns in some images.
– Nearest neighbor: interpolation by pixel replication (should only be
used for line art).
– Maximum Optical Resolution: This feature allows PowerColor to set a
maximum optical scanning resolution for certain film types. Any reso-
lution above this value will be interpolated. This is very helpful when
scanning noisy or grainy originals that need to be enlarged beyond the
quality of the original.
Note:
The preferences you select, as well as all
window positions and contents, are saved by
PowerColor when the application is closed. The
next time you launch PowerColor, they will be
restored.
Note:
Changes made in the preference window
do not require the PowerColor application to be
restarted to take effect.
