11 CIRCUIT DESCRIPTION
11.1. Block Diagram-1 (Image Processing)
This scanner has 2 CISs (CIS (F), CIS (B)) to scan image signals for front and back sides respectively, in order to perform
duplex scanning. 
Both of them are available for duplex scanning in ADF mode. (When scanning on the Flatbed, only a CIS (F) is available.)
ASIC (F) (IC561) requires SDRAMs (IC527 to IC530) to memorize and output pre-processed or post-processed
image data for the front side. 
ASIC (B) (IC531) requires SDRAMs (IC533 to IC536) to memorize and output pre-processed or post-processed
image data for the back side. 
When a scanning starts, via CIS (F) RELAY Board, analog pixel signals scanned by CIS (F) are transmitted to 
AFEs (IC514 to IC517) on the MAIN Board.
At the same time, via CIS (B) RELAY Board, analog pixel signals scanned by CIS (B) are transmitted to AFEs
(IC518 to IC521) on the MAIN Board.
AFEs (IC514 to IC517) and AFEs (IC518 to IC521) converted the analog pixel signals to the digital.
The ASIC (F) (IC561) receives front image signals from AFEs (IC514 to IC517) on the MAIN Board, and then
pre-processes them.
And the ASIC (B) (IC531) receives back image signals from AFE (IC518 to IC521) on the MAIN Board, and then
pre-processes them.
(Pre-process means shading correction, line correction, and Dpi transformation.)
After finishing this, the ASICs (IC561 and IC531) post-process the data into binary or compressed data,
and send it to the PC via USB Interface.
(Post-process means binary processing (simple binary, auto binary, dither, error diffusion), color, or gray scale
image processing (MTF, Color Correction, Gamma Correction, and others).)
