PROBLEM TO BE SOLVED: To create an animation and display reproduction thereof by calculating the hologram at a high speed in creating a computer formed hologram. SOLUTION: Movements of individual objects after a timeΔt of three- dimensional data of an input object are detected by an object position information control means 902. The movements of each detected object are classified into groups of the same movement by a movement classification means 903. Interference fringes of light projected on the hologram surface after the timeΔt are formed for each group of the classified movements by a hologram pattern image processing means 904. The interference fringes of individual objects are formed by parallel displacement and rotation processing of a basic pattern. The formed interference fringes of each classification are stored in different buffers in a frame buffer 905. After all the movement groups have been processed, contents of each buffer is integrated in one buffer, and the interference fringes of the object after a time ofΔt are formed without the hologram re-calculated from the beginning. |
