D. Original reading control
• The light reflected off the original goes to the CCD sensor through the lens.
• The CCD sensor outputs an electric signal (analog) corresponding to the amount of light.
• The CCD sensor includes three separate photo receivers corresponding to each color R, G and B.
• The R, G and B analog signals are individually converted to a digital signal (A/D convert) in the CCD board
(CCDB).
• The A/D convert is controlled by the image processing board (IPB).
