HOLOGRAM TRANSCODING APPARATUS AND THE METHOD THEREOF

摘要

PURPOSE: A hologram transcoding device and a method thereof are provided to control the number of divided segments according to resolution of a fringe pattern, thereby playing an hologram with the same resolution. CONSTITUTION: A recording medium stores a fringe pattern for playing a hologram. A Fast Fourier Transform unit(30) divides the fringe pattern into a segment having a fixed size and performs Fast Fourier Transform about the fringe pattern recorded in the divided segment. An adding unit adds the fringe pattern of segments which the Fast Fourier Transform is performed. A phase shifting unit shifts the fringe pattern changed by the Fast Fourier Transform unit.
