ExposureAutoControl
ExposureAutoAdjustTol [Integer] R/W
Tolerance in variation from ExposureAutoTarget in which the auto expo-
sure algorithm will not respond. It can be used to limit exposure setting
changes to only larger variations in scene lighting.
ExposureAutoAlg [Enum] R/W
The following algorithms can be used to calculate auto exposure:
ExposureAutoMax [Integer] R/W
The upper bound to the exposure setting in auto exposure mode. This is useful
in situations where frame rate is important. This value would normally be set to
something less than (as a rough estimate)1x10
6
/(desired frame rate).
ExposureAutoMin [Integer] R/W
The lower bound to the exposure setting in auto exposure mode.
ExposureAutoOutliers [Integer] R/W
The total pixels from top of the distribution that are ignored by the auto expo-
sure algorithm.
ExposureAutoRate [Integer] R/W
The rate at which the auto exposure function changes the exposure set-
ting.100% is auto exposure adjustments running at full speed, and 50% is half
speed.
ExposureAutoTarget [Integer] R/W
The general lightness or darkness of the auto exposure feature; specifically the
target mean histogram level of the image—0 being black, 100 being white.
Range: [0–50] Default: 5 Unit: Percent
Mean [Default] The arithmetic mean of the histogram of the cur-
rent image is compared to ExposureAutoTarget,
and the next image adjusted in exposure time to meet this
target. Bright areas are allowed to saturate
FitRange The histogram of the current image is measured, and the
exposure time of the next image is adjusted so bright
areas are not saturated
Range: [Camera dependent] Default: 500000 Unit: µs
Range: [Camera dependent] Default: Camera dependent Unit: µs
Range: [0–1000] Default: 0 Unit: 0.01% i.e. 1000 = 10%
Range: [1–100] Default: 100 Unit: Percent
Range: [0–100] Default: 50 Unit: Percent
