10.9.4 Gain Auto
Gain Auto is the "automatic" counterpart to manually setting the Gain Raw parameter. When the
gain auto function is operational, the camera will automatically adjust the Gain Raw parameter
value within set limits until a target average gray value for the pixel data from the related Auto
Function AOI is reached.
The gain auto function can be operated in the "once" and continuous" modes of operation.
If the related Auto Function AOI does not overlap the Image AOI (see the "Auto Function AOI"
section) the pixel data from the Auto Function AOI will not be used to control the gain. Instead, the
current manual setting for the Gain Raw parameter value will control the gain.
The gain auto function and the exposure auto function can be used at the same time. In this case,
however, you must also set the auto function profile feature.
For more information about the "manual" gain settings, see Section 10.1 on page 157.
For more information about the auto function profile Section 10.9.6 on page 205.
The limits within which the camera will adjust the Gain Raw parameter are defined by the Auto Gain
Raw Upper Limit and the Auto Gain Raw Lower Limit parameters. The minimum and maximum
allowed settings for the Auto Gain Raw Upper Limit and Auto Gain Raw Lower Limit parameters
depend on the current pixel data format, on the current settings for binning, and on whether or not
the parameter limits for manually setting the gain feature are disabled.
The Auto Target Value parameter defines the target average gray value that the gain auto function
will attempt to achieve when it is automatically adjusting the Gain Raw value. The target average
gray value can range from 0 (black) to 255 (white) when the camera is set for an 8 bit pixel format,
from 0 (black) to 1023 (white) when the camera is set for a 10 bit pixel format, or from 0 (black) to
4095 (white) when the camera is set for a 12 bit pixel format.
