GL841 USB 2.0 2-in-1 Scanner Controller
The range is CCD or CIS minimum shift out time to 2096k pixels time , which can be adjusted by 1
pixel time increment.

Analog Front End Timing
External 16 bits Front-End for Wolfson WM8192, WM8199……etc.

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.
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 resolution) and dark shading by pixel (16 bits resolution),
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,white G2,dark G3,white 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 bits) 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.
