With the advent of projection,
the viewer’s relationship with the image was no longer private,
as it had been with earlier peepshow devices
such as the Kinetoscope and the Mutoscope,
which was a similar machine
that reproduced motion by means of successive images on individual photographic cards
instead of on strips of celluloid.
随着投影仪的出现，观众与图象的关系不再像早先的西洋镜那样是私密的。
西洋镜装置（例如K和M，M是一个和K相似的机器，不过，M通过一张张的摄影卡上的连续图象来重现动作，而不是像K那样通过条状明胶。）
