Exposure Alignment specifies how the exposure is executed in relationship to the sensor
capabilities and current frame trigger.
< DFNC Beginner >
Exposure is synchronous to the internal timing of the sensor. The readout is concurrent to
the exposure for the fastest possible frame rate. When a valid trigger is received and the
ExposureTime is shorter than the readout period, the ExposureStart event is latched in
the previous frame's readout. That is; the ExposureStartEvent is delayed and is initiated
when the actual exposure starts such that the exposure ends and readout begins as soon
as the previous readout has completed.
Specifies the delay in microseconds (µs) to apply after the FrameStart event before
starting the
ExposureStart event.
< DFNC Beginner >
Sets the exposure time (in microseconds) when the Exposure Mode feature is set to
Timed.
< Beginner >
Actual Exposure Time performed by sensor due to its design, based on the requested
Exposure Time.
< Beginner >
Selects which gain is controlled when adjusting
gain features.
< Beginner >
SensorAll Apply a gain adjustment within the sensor to the entire image. The first half of the gain
range is applied in the analog domain and the second half is digital.
DigitalAll Apply a digital gain adjustment to the entire image. This independent gain factor is
applied to the image after the sensor.
Sets the selected gain as an amplification factor applied to the image. User adjusts the
Gain feature or the GainRaw feature.
< Beginner >
Raw Gain value that is set in camera (Model Specific for range and step values).
< Guru>
Selects which Black Level to adjust using the
Black Level features.
< Beginner >
AnalogAll Sensor Dark Offset
Controls the black level as an absolute physical value. This represents a DC offset applied
to the video signal, in DN (digital number) units. The Black Level Selector feature
specifies the channel to adjust.
