I Want to do a project on Automatic Room Light Controller I just need help i have a cc camera and how can i interface it with microcontroller and check whether anyone is present in room if noone is present lights should be switched off
So you have done zero work yourself. You don't even know the interface(s) of that camera. Or if the camera can do image processing - if it can't then it should be obvious that: - you need to do the image processing - or find someone else to do it - or find other camera - or find other project - or give up
Why, does it have a particularly good method for interfacing cameras? Does it have a lot of memory for image storage, and processing? Is it particularly fast? Do you have some good programming and interface experience with it?
Suggest you google-up on video/camera capture methods/circuits on the internets.
