I remember that some of my colleagues had really tough time figuring out what is the sampling rate of a rolling shutter camera since camera producers never ever shown the value! We are not talking about the frame rate of camera if you are missing understanding. The reason was quite understandable, because the sampling rate of camera does not have a major impact to the quality of the picture and thus there is no need to display it to typical users. The trouble thing is, all of camera hardware are having different sampling rates and there is no standard sampling rate at all!
Now, we are not just using rolling shutter cameras for taking pictures but we wish to use them for communication. The first but indispensable parameter to know before we start is the sampling mechanism and the sampling rate of the camera. Undoubtedly, the rolling shutter camera has its pixel-rolling mechanism, and its hidden sampling rate (defined by the number of pixel rows sampled per second) must be experimentally explored firstly.
