Can I create a photo from my Iphone video?

I have the Iphone 4, when I take a video it has a bunch of screen shots at the top when I go to play it back, is there any way to make one of those screen shots into a photo.

I just saw a commercial for an android and it can do it, does anyone know if this is possible on the Iphone?

Well i guess you could play the video and pause and screenshot the desired moment (pressing the home and power button and the same time)

When your watching the video, pause it then press the screen so nothing is on it, then take a screen shot by pressing the home button and hold button(on top) at the same time then it will go to your camera roll
