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).
