● RED digital gain
It can change the RED digital gain when outputting Camera Link signal and RGB 8bit signal for the monitor.
Variable range is approximately 0.01 to 4-fold when assuming 0x40 as reference 1-fold in a fixed-point system.
Also, the sampling value (the average value of 15 points when
Gain is invalid) of each RGB output is displayed on OSD.
Example: When it is needed to multiply the RED digital gain by 1.25,
Enter the argument [H'50] to the communication command H'37.
● GREEN digital gain
It can change the GREEN digital gain when outputting Camera Link signal and RGB 8bit signal for the monitor.
Variable range is the same as that of RED digital gain.
● BLUE digital gain
It can change the BLUE digital gain when outputting Camera Link signal and RGB 8bit signal for the monitor.
Variable range is the same as that of RED digital gain.
● ON/OFF of the digital gain
It can confirm the status of digital gain of each RGB color. When this command is set to ON, any one of RED digital gain,
GREEN digital gain and BLUE digital gain is in valid status. If it needs to set the Digital gain to invalid status, change the
digital gain value of each color to H'40 or turn the one push white balance OFF.

(Note) Vsub voltage is appropriately adjusted before shipment, and therefore the setting value should not be changed
without a special reason. If the value is changed by mistake, it can be reset to the factory default by executing
"(6-5) Read out of factory default".
[Explanation] Vsub voltage
Vsub voltage is the bias voltage (substrate voltage) that serves to control the blooming effect (resulting in blur or running
image at a saturating area) that arises from excessive light getting into CCD.
If a high Vsub voltage is set, the blooming effect can be reduced, although an excessively high voltage leads to a narrower
operation range of CCD because it is associated with a decrease in the saturating voltage of the CCD output.
It is appropriately set before shipment because the optimum Vsub voltage varies by CCD.
