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
Yes, I seemed to have understood the requirements from the first post, I have a degree, I'm confused about what part of the project you're actually done, or capable to doing. Restating the requirements doesn't address what, if any, parts of the project you plan on working on, or where your design is.
You plan to do this with an 8051, any particular reason for that? You have an interface for the PAL/NTSC based cameras? You have something controlling the lights?
i want to implement it with 8051 , we are going to use relays for turning on/off lights . the only help i need is that how come i can determine whether room is empty or not and also do i need to use image processing and how to interface a camera (which has already been installed ) to microcontroller
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.
