Claim One:
1. An apparatus for displaying a holographic three-dimensional (3D) image, the apparatus comprising: a memory configured to store instructions; and a processor configured to execute the stored instructions to implement: an image segmenter configured to segment an original image of an object into a plurality of segments, and adjust a number of the segments per unit volume or the number of the segments per unit area according to a property of a light representing the original image; a calculator configured to calculate diffraction fringe pattern information for displaying each of the plurality of segments as a 3D holographic image; and a light modulator configured to form a diffraction fringe pattern according to the diffraction fringe pattern information and generate the 3D holographic image corresponding to the original image by modulating a light incident on the diffraction fringe pattern, wherein the image segmenter is further configured to pre-store information about a reference number of the segments related to a region of the original image represented by a light having a visible wavelength, and set the number of the segments per unit volume or the number of the segments per unit area in a region of the original image represented by a light having an invisible wavelength to be less than the reference number.
