Sample Size Options; Using The Pixel Display - Microtek ScanMaker IIG User Manual

Sample Size Options

This determines the expanse of color information to be made
available. For instance, if you choose 5 x 5 as your sample
area, this means your RGB values will represent color
information for a 5-pixel by 5-pixel area. If you choose 1 x 1,
the color information pertains to a single pixel — the one in
the middle of the Pixel Display.
The 1 x 1 sample size means
the RGB numbers represent the
color value of a single pixel —
the one in the middle of the
Pixel Display.
The 5 x 5 sample size means
the RGB numbers represent
the average value of a 5-pixel
by 5-pixel area. This would
include the whole of the Pixel
Display (which is 5 pixels long
and 5 pixels wide).

Using the Pixel Display

The Pixel Display helps you see how color pixels are orga-
nized and distributed. The display can then help you make an
informed judgment on how best to modify image characteris-
tics such as shadows and highlights, and also allow you to
verify any changes that are made.
