Dynamic images such as computer graphics animation, moving things captured by video camera are always composed of several images as frames. This paper proposes one of the mathematical formulations for such animations. The key idea of our formulation is that each of the pixels representing an image is regarded as a kind of potentials in vector fields. Based on the vector calculus in classical physics, any static and dynamic images can be represented by the Poisson- and Helmholtz- type partial differential equations, respectively. This makes it possible to handle any images as analytical and continuous quantity even though these are given in terms of the discrete ones.Further, it is clarified that the animation technology is closely related with the simulation one. In the present paper, we carry out one of the simulations for magnetodynamic fields in ferro-magnetic material to show the relationship between the animation and simulation methodologies. As a result, it is demonstrated that our animation methodology reproduces the simulated magnetodynamic fields. Thus, it is found that our approach has versatile capability for analyzing the electric and electronic devices.
