It is used to select the metering area.
Fulling Metering: During metering, all
areas of an image have equal weight,
that is, all areas are involved in the
metering.
Spot Metering: During metering, the
central spot of an image has the highest
weight.
Partial Metering: During metering, the
middle area (1/2 of the total area) of an
image has the highest weight, and other
areas have the lowest weight.
The device automatically adjusts the shutter
time based on the ambient brightness. The
shutter time is less than or equal to the value
of this parameter.
The device automatically adjusts the gain
based on the external light. The gain is less
than or equal to the value of this parameter.
It is valid in manual mode and iris priority
mode. You can adjust the brightness of an
image by setting the iris. As the value
increases, the brightness increases (when
the shutter and gain remain the same).
However, the camera movement
automatically adjusts the shutter and gain in
this mode. Therefore, the brightness of an
image may not increase when you increase
the iris.
It is used to control the light admitted to the
lens.
The auto iris can be set to either of the
following states:
Auto
The iris is automatically adjusted to
control the light admitted to the lens.
Open fully
The iris is fully open.
It indicates the auto adjustment speed of the
iris. As the value increases, the speed
increases. Excessive speed may cause
instability.
This parameter is valid when the auto iris is
enabled.
