Abstract:
Disclosed are a method and an apparatus for hologram printing using a mask. According to an embodiment of the present invention, a hologram printing method comprises: generating a hologram fringe pattern; dividing the hologram fringe pattern in units of hogels; generating divided hogels; masking a part of the generated hogels; and recording the masked hogels in a hologram medium.
