iammuchhonoredtoetothefrontspeakers;thisismycurrenttheme-animation 早在1831年，法国人josephantoineplateau把画好的图片按照顺序放在一部机器的圆盘上，圆盘可以在机器的带动下转动。这部机器还有一个观察窗，用来观看活动图片效果。在机器的带动下，圆盘低速旋转。圆盘上的图片也随着圆盘旋转。从观察窗看过去，图片似乎动了起来，形成动的画面，这就是原始动画的雏形。

1909年，美国人winsormray用一万张图片表现一段动画故事，这是迄今为止世界上公认的第一部象样的动画短片。从此以后，动画片的创作和制作水平日趋成熟，人们已经开始有意识的制作表现各种内容的动画片
