7.2.2 Setting the Gain
The camera’s gain is determined by the value of the Gain parameter. The regular parameter value
is adjusted on a scale ranging from zero to a maximum value. The minimum regular value depends
on whether vertical binning is enabled (see Table 44). The maximum allowed parameter value can
depend on whether the camera is set for a pixel format that yields an effective pixel bit depth of 8
bit per pixel (e.g. Mono 8, RGB 8, Bayer BG 8, YCbCr422_8), of 10 bit (e.g. Mono 10, Mono 10 p,
Bayer BG 10, Bayer BG 10 p) or of 12 bit (e.g. Mono 12, Mono 12 p, Bayer BG 12,
Bayer BG 12 p).
Table 44 shows the minimum and maximum settable gain for each camera model. The values
indicate regular settings, i.e. the parameter limits are not removed.
This section (Section 7.2) describes how gain can be adjusted "manually", i.e., by
setting the value of the Gain parameter.
The camera also has a Gain Auto function that can automatically adjust the gain.
"Manual" adjustment of the Gain parameter will only work, if the Gain Auto
function is disabled. If the Gain Auto function is enabled the Gain parameter will
merely be in a "read only" state.
For more information about auto functions in general, see Section 7.15 on
page 294. For more information about the Gain Auto function, see Section 7.15.4
on page 302.
Before setting the Gain parameter value the GainSelector parameter value must
be set. The GainSelector parameter specifies the type of gain that is controlled by
the Gain parameter.
The only available GainSelector parameter value is All. Accordingly, the Gain
parameter is of the type All.
