6.12.3 MISRECOGNITION OF AUTO COLOR SELECTION WHEN
SCANNING ORIGINALS
In Auto Color Selection (ACS) mode, 2 processes are carried out, namely
(1) Chromatic Color Recognition and (2) Size Recognition, to determine
whether the scanned original is full color or black-and-white.
In (1) Chromatic Color Recognition, each pixel is assessed for whether it has a chromatic color
or not according to its RGB deviation.
