Limited animation is a process of making animated cartoons that does not redraw entire frames but variably reuses common parts between frames. One of its major characteristics is stylized design in all forms and shapes, which in the early days was referred to as modern design. The short-subject and feature-length cartoons of Walt Disney from the 1930s and 1940s are widely acclaimed for depicting animated simulations of reality, with exquisite detail in every frame. This style of animation is time-consuming and expensive. "Limited" animation creates an image with abstract art, symbolism, and fewer drawings to create the same effect, at a much lower cost. This style of animation depends upon animators' skill in emulating change without additional drawings; improper use of limited animation is easily recognized as unnatural. It also encourages the animators to indulge in artistic styles that are not bound to real-world limits. The result is an artistic style that could not have developed if animation was solely devoted to producing simulations of reality. Without limited animation, such groundbreaking films as ''Yellow Submarine'', Chuck Jones' ''The Dot and the Line'', and many others could never have been produced. The process of limited animation aims to reduce the overall number of drawings. Film is projected at 24 frames per second. For movements in normal speed, most animation in general is done "on twos," meaning each drawing is displayed twice, for a total of 12 drawings per 24 frames per second. Faster movements may demand animation "on ones" with a new drawing in each frame, while characters that do not move may be done with a single drawing (a "hold") for a certain amount of time. It is said that the Disney average was about 18 drawings per second, pretending that all characters of a scene share the same sheet of paper. Limited animation mainly reduces the number of inbetweens, the drawings between the keyframes which define a movement, and can cause stuttering if inbetweens are poorly set up. Overall, the use of limited animation does not necessarily imply lower quality as it allows the use of many time-saving techniques that can improve the quality and flow of the keyframes and overall presentation of an animation. ==History== The use of budget-cutting and time-saving animation measures in animation dates back to the earliest commercial animation, including cycled animations, mirror-image and symmetrical drawings, still characters, and other labor-saving methods were employed. In general, the progression was from early productions in which every frame was drawn by hand, independent of each other drawing, toward more limited animation that made use of the same drawings in different ways. Winsor McCay, a man who put an unprecedented amount of detail into his animations, boasted that in his 1914 film ''Gertie the Dinosaur'' that everything moved, including the rocks and blades of grass in the background. In contrast, his 1918 film ''The Sinking of the Lusitania'' progressed to using cels over still backgrounds, while still maintaining a level of detail comparable to that of ''Gertie''. The 1942 ''Merrie Melodies'' short ''The Dover Boys'' was the first Warner Bros. cartoon to employ some techniques of what would become known as "limited animation",〔Chuck Jones: Extremes and In-betweens - A Life in Animation (PBS 2000)〕 but their use was sparse and pressure from Warner Bros. curtailed further use of these techniques. Limited animation as an artistic device and a style was pioneered in the animation studio UPA, which made the first serious effort to abandon the keyframe-heavy approach perfected by Disney. UPA's first effort at limited animation, ''Gerald McBoing-Boing'', won an Oscar, and it provided the impetus for this animation method to be accepted at the major Hollywood cartoon studios, including Warner Brothers and MGM. However, the real attraction of limited animation was the reduction in costs: because limited animation does not require as many drawings as fully keyframed animations, it is much less expensive to produce. The 1950s saw all of the major cartoon studios change their style to limited animation, to the point where painstaking detail in animation occurred only rarely. Limited animation techniques in America were used during the 1960s, 1970s and 1980s to produce a great number of inexpensive Saturday morning cartoons. Such TV series as ''Clutch Cargo'' are known for being produced on extremely low budgets, with camera tricks used in place of actual animation. Despite the low quality of the animation, the TV cartoon studios Hanna-Barbera, DePatie-Freleng Enterprises, Jay Ward and Filmation thrived during this period. The desire of the time to emulate full animation with limited animation led to many highly apparent visual issues. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Limited animation」の詳細全文を読む スポンサード リンク
