Abstract
In the present invention, by receiving three-dimensional spatial data for a three-dimensional object, calculating a size of an elemental fringe pattern for each depth and a maximum size of the elemental fringe pattern for the three-dimensional spatial data, dividing the entire resolution of an entire predetermined hologram into a plurality of segments based on the number of divisions of the horizontal direction and the vertical direction, expanding resolution for each segment based on a maximum size for the elemental fringe pattern size, calculating a plurality of segment unit holograms for each of the segments, and accumulating overlapping regions between the plurality of segment unit holograms to produce the entire hologram for the entire resolution, it is possible to provide a hologram generating apparatus and method which may generate a hologram having a higher resolution at a faster speed than the conventional one.
