cameras in igor 7

Share icon

i am quite eager to use this, but would like to see an example how i might adjust parameters of a given camera. Is there some material about how to use this except from the help file?
at the moment it seems there is nothing i can do with a camera window but sit and watch...
I have libraries in .NET, ActiveX and directShow format. Are these needed to have better control of the camera?

The author of the new camera code is out of the office this week, but as far as I'm aware there isn't any additional documentation for this feature outside of the help for the NewCamera, GetCamera, and ModifyCamera operations. The Qt library that Igor is calling into was designed mostly for cell phone cameras, so many of the different commands that are theoretically supported aren't supported in practice because webcams don't support those features. But it's possible you do have a camera that might support some of the more advanced features. Your .NET, ActiveX, and DirectShow libraries would only be useful if you wanted to write an XOP to control your camera.

If you give specifics of what parameters you want to adjust and what camera hardware you are using, we might be able to provide more focused assistance.

If you are able to watch video you should be able to capture images. All camera control is provided under the ModifyCamera operation. You can execute:
DisplayHelpTopic "ModifyCamera"

for more details.

It is in general not practical/possible for us to provide specific examples because of the vast number of camera models and different versions of their drivers. Our camera operations are built on top of Qt camera API which tries to support (usually) built-in cameras or cameras supported under generic drivers. Note that although technologies such as DirectShow may provide access to controlling capture parameters, it turns out that very few camera drivers actually support these features.

If you are really looking for full feature support and you have the relevant libraries, you should write an XOP for your camera. You can contact support@wavemetrics.com for more specific help.

I have been able to get a camera image, I'll try to play if can modify exposure time etc.
