an image displayed on a monitor.

Preview Area

The right side of the FilmGet FAU main window, which is used to
display preview images. Click the [Preview] button to initiate a
preview scan of the objects on the scanner platen. The image
displayed in the preview area has not yet been acquired by the
application program from which FilmGet FAU was started.
Resolution

coarseness of an image is expressed as the number of dots per inch
(dpi). See 'dpi.'
RGB
The acronym for the primary colors: red, green and blue. The scanner
passes light through the film, which is then detected by red, green
and blue sensors. Color printers, on the other hand, use the comple-
mentary colors to RGB, namely cyan, magenta, yellow and black
(CYMK) to express colors.

tions. Start the scanner self test from the [Device] menu.
