You might check and see how you paid for it and the length of the original warranty. Typically, something like a camera will have a one year manufacturer's warranty. I know that with certain restrictions, American Express will double the manufacturer's warranty if you you purchased the item using their card. Visa or MasterCard may do likewise.
For extended warranties in general, I use Clark Howard's philosophy, and opt out for anything electronic. The price for electronics is cut in half every year for similar technology, and the technology doubles. Put that extra money in a savings account for the replacement. My camera now has a small dent in the sliding cover, after a kid dropped it, and when turning off the camera, I have to give it a solid tap to close the door completely. I don't think the designers thought that people would actually carry their cameras in their pockets every where they went. I do, and it gets plenty of wear and tear.
As Kurt said, sending back for repair outside of warranty will probably cost you $60 for them to look at it. Even more for parts and or repair, and they might tell you that it isn't repairable. What kind of camera is it? an SLR, or pocket cam?
