ExposureTime Property
Applies To
Vision Sequences
Description
Sets the electronic exposure time for a camera.
Usage
VGet Sequence.ExposureTime, var
VSet Sequence.ExposureTime, value
- Sequence
- Name of a sequence or string variable containing a sequence name.
- var
- Long expression for the new value of the property.
- value
- Long integer expression for the new value of the property.
Values
Long value in microseconds.
Default: 0 (microsecond)
| Camera | Default |
|---|---|
| NET 1044 BU | 26000 microseconds |
| NET 4133 BU / CU | 26000 microseconds |
| NET 1500 BU / CU | 26000 microseconds |
| acA640-100gm | 8000 microseconds |
| acA640-120gm | 8000 microseconds |
| acA1300-60gm | 5000 microseconds |
| acA1600-20gm / gc | 10000 microseconds |
| acA1600-60gm / gc | 10000 microseconds |
| acA2500-14gm / gc | 35000 microseconds |
| acA2500-20gm / gc | 5000 microseconds |
| acA3800-10gm / gc | 35000 microseconds |
| acA5472-5gm | 10000 microseconds |
| acA5472-5gc | 100000 microseconds |
Remarks
When RuntimeAcquire is “1-Stationary” and ExposureTime is 0, the exposure time is set to default value.
When RuntimeAcquire is “1-Stationary” and ExposureTime is grater than 0, the camera acquires images in the specified exposure time. When the sequence runs, the camera sensor is exposed for the ExposureTime, and then the image is acquired.
