Gain Control

[Analog All] can be used for gain control for both the monochrome and color camera. [Analog All]
(master gain) uses the sensor's internal gain function and consists of analog gain + digital gain.
Analog gain is used for lower gain, and analog gain + digital gain is used when the gain becomes
high. R and B can be configured individually as digital gain on the GO-5101C-PMCL.
 For details on how to configure the settings, see "Adjusting the Gain" (page 20).
The relationship between the gain setting value, gain amplification, and dB value is as follows. For
example, a gain amplification of x5.62 will be 15 dB.
