1 GENERAL DESCRIPTION
Genesys Logic's single-chip GL841 (GeneScan™ series) is a high speed, high
performance, low cost and rich scalability controller for scanner. It successfully
integrates scanner function ASIC and USB 2.0 interface controller into one
single-chip. With its high performance design architecture, GL841 is not only
ready for supporting CIS or CCD image sensors (600dpi,1200dpi or 2400dpi
resolution) that are used in flatbed or transparency scanners, but is able to cowork with uni-polar or bi-polar stepping motors. Advanced features of GL841
include five motor acceleration/ deceleration curve tables for high speed motor
moving.
2 FEATURES

6.4 Fast scan for low DPI
Speed up CCD clocking rates allows speeding up scanning speed.
Such as Stagger CCD, you can speed up 2 times,4 times scanning time for low resolution as 600dpi
scanner: if 75dpi speed up 4 times then 1.620ms/4=0.405ms/line.
Scan speed is equal to 0.355s/page.
6.5 Scanning Type
Support three line in(parallel ) for CCD, one line in for CIS two types.

6.6 Image Sensor Timing
Can be programmed.
A. CCD : support 600,1200 or 2400 dpi CCD.
For example NEC, TOSHIBA, Sony ……etc.
B. CIS : support 600,1200 or 2400 dpi CIS.
For example Toshiba , Canon……etc.
6.7 Dummy Line
Support programmable dummy lines to resolve (overcome) Start/Stop problem.
You can insert dummy lines to reduce scanner stop and wait events (buffer full) or always non-stop.
A. Line base of dummy lines:
The range of dummy lines is 0 line ~ 15 lines.
B. Adjustable dummy line:
The range is CCD or CIS minimum shift out time to 2096k pixels time , which can be adjusted by
1 pixel time increment.
6.8 Analog Front End Timing
External 16 bits Front-End for Wolfson WM8192, WM8199 ……etc.
6.9 Image Type
Support color, fine gray, fine line art, fast gray and fast line art scan.
Support color filters selection for gray and line art scans. The filters include Red, Green and Blue.
Note: The scan style of fine line art, fine gray or color are the same. So fine gray or fine line art
scanning speed is slow.
Page 17

Version 1.6
17
The exposure time of fast line art or fast gray scan is shorter than fine line art or fine gray scan.
So, fast line art or fast gray scanning speed is high.
6.10 Bits Depth
16 x3 Bits true color , 16 bits gray level and one bit line art(Black & White).
Image data type : 16 bits , 8 bits and 1 bit data type.
6.11 Shading & Correction
a. White Shading & Dark Shading:
Internal white shading by pixel (16 bits resoluti on) and dark shading by pixel (16 bits re s olution),
can be enabled or disabled By S/W. The white shading curve is calculated by S/W.
Data arrangement: three line in mode: dark R1,white R1,dark G1,white G1,dark B1,white B1,
dark R2,white R2,dark G2,white G2,dark B2,white B2,
dark R3,white R3,dark G3,white G3,dark B3,white B3,……
one line in mode:dark R1,white data R1,dark R2,white R2,dark R3, white R3…
dark G1,white data G1,dark G2,w hi t e G2,d ar k G3, whi t e G3…
dark B1,white data B1,dark B2,white B2,dark B3,white B3…
White shading formula : 2000H x Target / (Wn-Dn) = White Gain data ----- for 8 times system
White shading formula : 4000H x Target / (Wn-Dn) = White Gain data ----- for 4 times system
For example : Target = 3FFFH Wn = 2FFFH Dn = 0040H and 8 times system operation
then White Gain = 2000H x 3FFFH / (2FFFH-0040H) = 2AE4H (1.34033 times)
b. Gamma Correction :
GAMMA correction table is calculated by S/W. The resolution is 16 bits gamma table.
Range: 0 to 64k (16 bi ts) input mapping to 0 to 255 (8 bits) output ;
Style : increment or decrement gamma curve style.
Note: If you bypass gamma correction , you can get 16 bits image data.
If you enable gamma correction , you can get 8 bits image data.
