Can I take the image feed from Analog Camera using OpenCV, in a similar manner as it is done using the Digital Camera?
As-In the concept of FPS, does that work similarly with the Analog Camera's?
One option I used in the past is a Video to USB Converter.
I didn't try it, but the camera interface should work directly with the OpenCV capture functionality.
Analog cameras have a fixed FPS. If I am not mistaken it is different for PAL and NTSC, try searching for it.
