ashwinkumar,
Welcome to the weird and wonderful world of Windows webcams in Linux!
Some people assume that because their webcam works perfectly in Windows, then it will also work in Linux. WRONG!
Some Windows webcams will work easily in Linux, some will work after a lot of effort and some will never work in Linux.
Someone called smileone using Debian Lenny appears to have got your webcam working here:

With any luck you should be able to get your webcam to work.
Give it a try but do not waste too much time on it. If all else fails, you may find it simpler to sell your existing webcam and buy a cheap Logitech webcam that is Linux compatible.
Do make sure that you check the Linux user feedback on any webcam before purchase.
