CHAPTER 2 FUNCTIONS & OPERATION
3) Automatic Brightness Adjustment
This adjustment automatically controls the
brightness of the scanned image according to the
density of the document’s background in the
simple binary mode.
The brightness is adjusted by assessing the
brightness line by line, and adjusting the level for
the next line to be scanned.
This process is known as ABC (Auto
Back-ground Control).
When the number of pixels of specified
brightness in a line exceeds the predetermined
value for the document size, the brightest output
is transformed gradually, line by line.
Fig. 2-516 shows the difference in output
when reading a text document with a colored
background.
