My 640x480px camera is not enough and I need to increase the resolution. I'm planning to buy the Microsoft Lifecam Studio (1920x1080) but can I use the maximum resolution on the cam together with opencv? Is there any limit for the "videoDevice >>" when capturing frames from the webcam?
As soon as the frame is grabbed the system will only use the ROI, so my question is mostly about the frame grabbing. Can opencv grab frames that big?

edit 2: extra question
I've searched google about web cam with ROI, but I guess that ROI is a term used only when talking about opencv, because i Couldnt find anything.
Is there anyone that knows which cameras there is that has some kind of ROI - function built into the hardware so that the amount of data to grab is less for the software?
Thanks!
