8.1.1 Setting the Gain
The camera’s gain is determined by the value of the All parameter. The parameter is adjusted in
[dB] on a scale ranging from zero to a maximum value. The minimum regular value depends on
whether vertical binning is enabled (see Table 30). The maximum allowed setting depends on
whether the camera is set for a pixel format that yields an effective pixel bit depth of 8 bit per pixel
(Mono 8, RGB 8, BGR 8, Bayer BG 8, Bayer GB 8,YCbCr422_8) or of 12 bit (Mono 12, Mono 12 p,
Bayer BG 12, Bayer GB 12, Bayer BG 12 p, Bayer GB 12 p).
Table 30 shows the minimum and maximum settable gain [dB] for each camera model.
Model
This section (Section 8.1) describes how gain can be adjusted "manually", i.e., by
setting the value of the gain All parameter.
The camera also has a Gain Auto function that can automatically adjust the gain.
"Manual" adjustment of the gain All parameter will only work, if the Gain
Auto function is disabled. If the Gain Auto function is enabled the gain All
parameter will merely be in a "read only" state.
For more information about auto functions in general, see Section 8.11 on
page 209.
For more information about the Gain Auto function, see Section 8.11.4 on
page 217.
