GL646USB
Scanning type: line by turns
R
G
B
You can control R, G or B exposure time separately.
For example, above case B exposure time is three times of R; G exposure time is two times of R.
6.15. Scan Width control
Scan width control for horizontal line
a. Support start pixel address, end pixel address and dummy pixel number setting
b.
Maximum length: 64k pixels.
Minimum length: 1 pixel
6.16. Support built-in USB(1.1) , external USB(2.0) and external IEEE1394 Interface
Support 4-type operation.
Three in one: USB1.1 + AFE + scanner controller
Two in one:
A. AFE + scanner controller + (external) USB2.0
B. AFE + scanner controller + (external) IEEE 1394
C. USB1.1 + scanner controller + (external) AFE
Note: Instead of our build-in AFE, you can use other external AFE.
6.17. DRAM Timing
Support 4Mx1 or x2 Bits EDO DRAM (16 x 256K) image buffer and calibration buffer timing.
You can select single or double DRAM for scanner. DRAM speed is 35ns and above for 24MHz system clock,28ns
and above for 32MHz system clock.
6.18. Horizontal Resolution Adjustable for DPI Function
A. Digital deletion type :
The resolution from 1 DPI to 1200 DPI , can be adjusted by 1 DPI increment by S/W.
B. Digital average type :
Support 1/2,1/3,1/4,1/5,1/6,1/8,1/10,1/12,1/15 digital average function.
For example, 1200dpi scanner: 600dpi, 400dpi, 300dpi, 240dpi, 200dpi,150dpi, 120dpi, 100dpi, 80dpi
average function.
C. CCD DPI process :
Support 1/2,1/3 and 1/4 resolution.
For example, 1200dpi scanner: output 600dpi, 400dpi and 300dpi process.
6.19. Vertical Resolution Adjustable for DPI Function
