The word animation comes from Japan. Osamu Tezuka applied the sense of lens in movies to cartoons, which gave them a lens. Nowadays, Japanese animation draws on many expressions of cartoons, so animation can be understood as dynamic cartoons, while the earliest cartoons in the United States are humorous and satirical cartoons, and later animators have a great influence. So the United States defines animation as an animated film. From the performance differences between American and Japanese animation, it can be seen that Japanese animation often changes the lens to describe the plot, while American animation characters are performing.
