Answer:

12 images and this is called frame rate

Answer 2

12 images per second need to be projected on the screen in order to see a moving picture.

• The video which we see in mobile,tv, movie theatres are actually the long chains of still pictures which are showed very rapidly,so that our eyes get an illusion of motion happening in the screen.

• Our eyes can feel the proper motion if 12 pictures are shown per second but the video quality will be very choppy.

• If we increase the frame rate from 12 we will constantly get a smoother motion on the screen.

• Typically 24 fps and 60fps are the standard frame rate amounts which we are currently using in the major entertainment industries.
