title: Increasing camera capture resolution in OpenCV
body: <p>In my C/C++ program, I'm using <a href="http://opencvlibrary.sourceforge.net/" rel="noreferrer">OpenCV</a> to capture images from my webcam. The camera (<a href="http://en.wikipedia.org/wiki/Quickcam" rel="noreferrer">Logitech QuickCam IM</a>) can capture at resolutions <strong>320x240</strong>, <strong>640x480</strong> and <strong>1280x960</strong>. But, for some strange reason, OpenCV gives me images of resolution <strong>320x240</strong> only. Calls to change the resolution using <strong>cvSetCaptureProperty()</strong> with other resolution values just don't work. How do I capture images with the other resolutions possible with my webcam?</p>
