Aim a video camera at it.

Unless you use a second camera what you ask isn't possible. Unless you mean a simple screenshot still image: hold the power key down and then press the home key to take a single photo of the screen image.

Search for screen recorder on the App Store and try what comes up. There's a lot of trash on there so it might take a while to find a good one.
