Glossary
Brightness — Brightness and Contrast Control uses a brightness
scale from -50 (darkest) to +50 (lightest). Changing the Brightness
value will effect all color pixels in the image uniformly making all colors
in the entire image darker or lighter according to the values selected.
Contrast — Brightness and Contrast Control uses a contrast scale
from -50 (subtle) to +50 (sharp). As Contrast values become more
positive, darks become darker, and lights become lighter in order to
create as much distinction as possible between lights and darks.
GUI — graphical user interface.
Color Table — a file downloaded to the scanner which contains the
information required for the scanner to output the desired color. Only
one table may be resident in the scanner. Multiple tables may be saved
as files on the host PC. Each scanner family has a unique file format.
Color tables cannot be shared across scanner platforms. Color tables
are stored using the file extension .ekct. Kodak provides default color
tables which are bundled and installed with the Scan Validation Tool.
For more information about these default tables (a description of each
and when you would you use it), see the Image Processing Guide for
your scanner. One or more of the default color tables should meet your
needs, if not, this tool may be used to create your own custom color
table. For Kodak service testing purposes a Kodak default color table
will be used.
SVT (Scan Validation Tool) — a diagnostic application provided by
Kodak to test your scanner to verify scanner functionality. For detailed
information about the SVT, see the Image Processing Guide for your
scanner.
JPEG — Joint Photographic Experts Group (compressed image
format).
NULL color table — a table used by the scanner in place of a color
table which does not modify the raw image data, and therefore, can be
used to create an uncorrected image.
RGB — Red, Green, Blue. Brightness and Contrast Control uses 24-bit
color images. Each pixel in the image has an 8-bit Red value (0 to 255),
an 8-bit Green value (0 to 255) and an 8-bit Blue value (0 to 255).
Uncorrected image — a color image created using a NULL color table
(raw image from the scanner).
