ABSTRACT:
A method of recording (preserving) and reproducing an image is disclosed. The x and y axes are assumed on the plane of an original image, the z axis (density axis) is assumed to be perpendicular to the x and y axes, and a space defined by the x, y, and z axes is divided into rectangular solid cells. The volume ratio below a density distribution curved surface of the volume of each rectangular solid is recorded. Upon reproduction, the curved surface is reproduced based on the volume ratios of the rectangular solids which the density distribution curved surface crosses, and those of rectangular solids adjacent thereto.
In a four-dimensional Euclidean space defined by an image plane (x,y), a density or brightness D, and time or a frame f, an image is expressed by a solid in this space. This space is divided into four-dimensional rectangular solids, and an amount proportional to the volume of the solid in each rectangular solid is recorded or transmitted. Upon reproduction, the solid is reproduced based on the volume amounts of the rectangular solids and those of rectangular solids adjacent thereto, thereby reproducing a dynamic image.
