Binary reading
[A.3.3.2 CONTROL command / Control register A#1/B#1= B’xxxxxx0x’]
Following three parameters are available when binarizing the image. The 256 levels of the density at
each pixel is processed by Contrast and binarized by fixed Threshold (Density). When the White
level following is se ON, the white level of the CCD output follows the background of the document.
So this is useful for line art drawing but not for photograph.
