We're trying to setup a camera station in one of our anatomy labs at work. What we want to be able to do is have the camera connected to a Windows PC and use the camera for both video chat and high-res still image capture. Preferably it would be able to perform both functions simultaneously. This would all for us to be sharing video of tissue with a remote physician and when he asked for a still we could alt+tab over and get a good high-res image from the same camera. A point and shoot type camera would be preferable but would just like to know about my options so I can estimate cost.
