This project i am doing only for learning linxu and its API and how hardware interface done in linux.

Please help me to understand, how to start and where to start.

Most linuxes today use the UVC driver to control webcams. You might want to take a look at the UVC driver documentation in the linux kernel source code: Documentation/video4linux/uvcvideo.txt. Most userspace tools will use the v4l2 interface i.e. /dev/videoX device.

Here's an example I found with a quick search: **broken link removed**

For a more detailed code I recomment you download and look at the source code of one of the open source webcam projects i.e. Fswebcam.
