13 Exposure Time
Maximum: 2096k pixels time
Adjustment step: 1 pixel time.
For transparency scanning, the exposure time can be up to 2096k pixels time.
14 Scan Width control for Horizontal Line
a. Supports start and end pixels assignment in setting scan width.
b. Scanning width= end pixels - start pixels
Maximum length: 128K pixels.
Minimum length: 1 pixel.
15 Support built-in USB 2.0 Controller
2-in-1 USB2.0 controller + scanner controller.
16 SDRAM Timing
Supports 16M Bits (1M*16), 64M Bits (4M*16), 128M Bits (8M*16), 256M Bits (16M*16) and 512 M Bits
(32M*16) SDRAM as image buffer and calibration buffer.
17 Horizontal Resolution Adjustable for DPI Function
A. Digital deletion type:
Software adjustable resolutions range from 9600 to 1 dpi with 1 dpi decrement.
B. Digital average type:
Supports 1/2, 1/3, 1/4, 1/5, 1/6, 1/8, 1/10, 1/12, 1/15 digital average function.
For example, options for 1200dpi scanner are:
1200dpi, 600dpi, 400dpi, 300dpi, 240dpi, 200dpi, 150dpi,120dpi, 100dpi, 80dpi by average function.
C. Support stagger CCD:
Supports 1/2, 1/4, 1/8 resolutions, such as NEC Toshiba and Sony stagger CCD.
18 Vertical Resolution Adjustable for DPI Function
The resolution of motor moving is 16 bits wide and is flexibly controlled by motor tables.
The resolution can be up to 4800 dpi for 1200 dpi scanners, 9600 dpi for 2400 dpi scanners and 19200 dpi for
4800 dpi scanners.
Note: The resolution of vertical direction of quarter step can up to four times resolution.
19 Five Acceleration/Deceleration Tables
The acceleration/deceleration tables are stored in internal SRAM and can be downloaded by S/W.
And the resolution is 16 bits in pixel-time. The number of table steps is from 1 to 1020 steps for arbitrary
curves. There are five tables for motor moving. Three tables are for scanning and the others are for fast
moving. The forward and backward steps can be programmed by S/W separately.
Note:
“
Fast move
”
means move back to home position or move forward to scan window in any position.
