Monochrome Field Update Line Scan Camera Link Series
6.1.3 Auto FFC Procedure
After the target gain and offset levels have been set, the camera will correct the gain and offset value
automatically under the calibration setting.
The user has to set the FFC under their personal conditions. If the wrong procedure is executed, the
correction can be recovered from the beginning.
[Procedure]
1) Set the OFF on [FFC Mode] [81h: 0]
(This register is the trigger at 4)
2) Set the value on [Target FFC Offset] [8Ah: 5]
(Set the offset value (range: 0 to 255, recommended: 5)
3) Shield the light.
4) Set the Auto(offset) on [FFC Mode] [81h: 6]

5) Set the ON (only Offset) on [FFC Mode] [81h: 7]
(This setting is necessary to determine the target level for checking the actual video image at the
next step.)
6) Un-Cover the sensor
Please do not saturate the image.
Focus the camera on a smooth white clean object for calibration and set the parameters to the
actual condition.
Note:
If the case is “Auto Target”
jump to step 11
Auto Target is the function that sets the target gain level automatically.
The formula Target gain level = Maximum light receiving level
+ α is used to determine the target
gain level.
If the case is “Fixed Target Level”
