Adjusting Contrast and
Brightness
Often in scanned images, colors may be too light or dark to show
details clearly. Use the contrast and brightness adjustments in the
Copier menu to improve the quality of the scanned image. See chap-
ter 2, “The CrownCopy Menu” section, for more information on these
options.
Brightness
Brightness is the perceived quality of radiance or luminosity of a
visual object. Increasing brightness (moving the setting in the L direc-
tion) makes light and dark areas in the image appear lighter.
