Kinetoscope \Ki*ne"to*scope\, n.
   A machine, for the production of animated pictures, in which
   a film carrying successive instantaneous views of a moving
   scene travels uniformly through the field of a magnifying
   glass. The observer sees each picture, momentarily, through a
   slit in a revolving disk, and these glimpses, blended by
   persistence of vision, give the impression of continuous
   motion.
