ExposureTime Property
Applies To
Vision Sequences
Description
Sets the electronic shutter time for a camera that is running in asynchronous reset mode.
Usage
VGet Sequence.ExposureTime, var
VSet Sequence.ExposureTime, value
Sequence Name of a sequence or string variable containing a sequence name.
var Long variable that will contain the value of the property.
value Long expression for the new value of the property.
Values
Long value in microseconds.
Default: 0 (microsecond)
Remarks
When RuntimeAcquire is Stationary and ExposureTime = 0, the camera acquires images in Next Frame
mode. When the sequence runs, the camera waits for the next valid frame, then acquires the image.
CameraGain and CameraOffset settings are used. Typical image acquire time is from 33 to 66 ms for
SC300 series.
When RuntimeAcquire is Stationary and ExposureTime is > 0, the camera acquires images in async reset
mode. When the sequence runs, the camera sensor is exposed for the ExposureTime, then the image is
acquired. CameraGain and CameraOffset settings are not used. Typical image acquire time is 33 ms +
Exposure time.
When RuntimeAcquire is Strobed, ExposureTime must be > 0, and the camera acquires images in async
reset mode. After the hardware trigger input is received, the camera sensor is exposed for the
ExposureTime, then the image is acquired. CameraGain and CameraOffset settings are not used. Typical
image acquire time is 33 ms + Exposure time.
