Defines the sensor height in active lines.
Specifies the camera frame rate in 0.1 fps steps.
Selects the exposure control operating mode.
The length of the exposure is controlled with the
"Exposure Time" feature. The exposure starts with
the trigger event.
Uses the width of the trigger signal pulse to control
the exposure duration. Use the Trigger Activation
feature to set the polarity of the trigger. The Trigger
Width setting is applicable with Trigger Selector =
Single Frame Trigger(Start). Available when using
Line1 or Line2 as trigger.
Note: the actual exposure time is 3 μs
longer than the trigger width. That is, the
pulse width is always 3 μs shorter than the
required exposure time.
Selects the sensor's exposure time mode.
Off For exposure times up to 50 000 µs.
For exposure times above 10 000 µs.
Specifies how the exposure is executed in relationship
to the sensor capabilities and current frame trigger.
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.
Sensor timing is reset to initiate exposure when a
valid trigger is received. Readout is sequential to
exposure, reducing the maximum achievable frame
rates. A trigger received during exposure or readout
is ignored since data would be lost by performing a
reset.
Specifies the delay in microseconds to apply after the
FrameStart event before starting the ExposureStart
event.
Sets the exposure time of the sensor in microseconds
(µs).
Measured Exposure Time in microseconds (µs).
Select the sensor shutter mode.
Select sensor global shutter mode.
Selects which gain and offset to control.
Analog Gain and offset applied to the sensor.
Apply a digital gain adjustment to the entire image.
This independent gain factor is applied to the image
after the sensor.
Video signal multiplier.
Selects which offset to control.
