[Function]
Control exposure period of sensor IC for R, G and B
independently.

ShutterEnd： Set end timing of exposure for RGB common
End timing[us]=ShutterEnd ×35
ShutterWidth_R,G,B ：
Set exposure period of RGB individually
Exposure period[us]= ShutterWidth_R,G,B ×35

[Remark]
1)This function is supposed to be used when you use an external
illumination (continuous-wave mode) with this product. When you
use illumination(LED) control signal from CIS, illumination(LED)
control function to adjust exposure period is recommended without
using this function.
2)Set the value of "ShutterEnd,ShutterWidth" fulfilling with the
following formula. (When setting Electric shutter ON, you need to
control each exposure period of RGB according to your
application.)
①Electric shutter ON (ShutterEnable='1')
A≦ShutterEnd ≦Line cycle (usec)×35 −6
A=620@600dpi, 358@300dpi, 262@200dpi, 214@150dpi
②Electric shutter OFF (ShutterEnable='0')
130≦ ShutterEnd ≦Line cycle (usec)×35 −6
※When you set the value of "ShutterEnd" is less than "①A" or "②130",
some defective images are output.
※When you set the value of "ShutterEnd" greater than "Line cycle x35-
6", a sync signal might be ignored and the number of the output line
may not correspond to the line cycle. When you use external trigger
mode, keep a margin between the value of "ShutterEnd" and Line cycle.
3)Set the value of "ShutterWidth_R,G,B" filfilling with the following
formula.
1≦ ShutterWidth_R,G,B ≦ ShutterEnd −1
4)
Electronic Shutter settings affect sensor outputs. When changing
Electronic Shutter settings, recommend to generate Dark /White
correction data again.
