Exposure control in IMAQdx

[chap]

Does anybody now how do I configure the exposure time from Labview?

I have a new Gig-e camera that works OK but the property nodes does not give this option.

I have everything needed (Imaq vision 8.2, Labview 8.2...)

thanks

Chaptsill,

You should be able to use the IMAQdx Enumerate Attributes.vi to make a list of all the attributes you are able to set for you camera.  Take a look at the screenshot.



Please let us know if you have any further questions or concerns related to this issue.

Regards,
Luke H

The available camera attributes are determined by the XML file as downloaded from the camera. In the case of a Prosilica camera, the exposure is controlled by the attribute: ExposureTimeAbs. In order to change the value, wire in the ActiveAttribute node with the string that represents the attribute you wish to change. Once you have selected the attribute, you may query the current value, min, max, increment, etc. You may also set the current value.



When specifying the ActiveAttribute as ExposureTimeAbs, you may use any variation on the string:
ExposureTimeAbs
FeatureControl::ExposureTimeAbs
CameraAttributes::FeatureControl::ExposureTimeAbs

Hope this helps,

JohannS

Hi jack!

Information about all the attributes can be found in the NI-IMAQdx  Function Reference Help.  It is included in the support when you install the IMAQdx driver.  It is located on your computer at Start >> Programs >> National Instruments >> Vision >> Documentation >> IMAQdx.  Once inside this folder, you should see the  NI-IMAQdx  Function Reference Help.  It has a help icon, too.  Have a great day!
