动画形象是一部动画片的重要标志,随着时间的推移、动画片的不断更新,动画形象必须做出相应的变化,但其动画形象的延续一般具有动态的相对稳定性。比如米老鼠的形象,从1928年诞生至今已有86年的历史,其演变过程宛如环环相扣的锁链,相邻两个扣环之间的变化非常小,维持着米老鼠形象延续的稳定性。这种变化是不易被人们察觉的,因为人眼对刺激物上的变化只有刺激量达到一定强度或在一定范围内才有可能被觉察。这也说明人类的视觉感觉存在着差别阈限。差别阈限是指感觉所能觉察的刺激物的最小差异量。德国心理学家韦伯发现:人对刺激变化的感受性和刺激量的变化存在
Animated images are an important symbol of animated cartoons. As the cartoons continue to be updated over time, the animated images must be changed accordingly. However, the continuation of their animated images generally has a dynamic relative stability. For example, the image of Mickey Mouse has been in existence for 86 years since its establishment in 1928. Its evolution is like a chain of interlocking rings. The change between two adjacent buckles is very small, maintaining the steady image of Mickey Mouse Sex. This change is not easy to be perceived as the human eye on the stimulus changes only stimulate a certain amount of strength or within a certain range may be aware of. This also shows that there is a difference between human visual perception of the threshold. The threshold of difference is the minimum amount of discrepancy in the stimulus perceived. German psychologist Weber found: people feel the changes in stimulus and stimulus changes exist
