A dog thought a cat was making a joke
but he was just kitten!
Kinetoscope cameraIn 1897, Thomas A. Edison received a U.S. patent for his kinetoscope camera, a device for producing moving pictures (No.589,168). In the patent, he described its purpose was “to produce pictures representing objects in motion throughout an extended period of time which may be utilized to exhibit the scene including such moving objects in a perfect and natural manner by means of a suitable exhibiting apparatus” by photography to expose a “sensitized tape-like film” with perforated edges. Edison determined that a speed of 30 pictures per second with the persistence of vision produced the effect of viewing the subject motion. While capturing each image, this rate was sufficient to move the film, yet allow a period of rest while each picture was exposed.« |
