I need advice from someone with knowledge of current web cams and web cams soon to be developed. For a project I'm working on I need the highest resolution consumer grade webcam available. I know that Hewlett-Packard (I think) recently came out with a three megapixel webcam. I've done a search for four megapixel cameras, and I have come up with a few made by foreign companies. Do you know if any of the major web camera manufacturers will come out with 4 megapixel cameras anytime soon? If not, are there any alternatives? I want something like a web camera because you can take a still image and have it immediately saved on the hard drive. I know that some SLR and other professional cameras can be operated from a PC with specialized software, but that is a prohibitively expensive solution for me. If anyone knows any kind of solution along these lines please let me know.
