Abstract: A method and apparatus for generating a holographic image from a low resolution image transformed into a low resolution complex image that is interpolated into a high resolution image complex image. By transforming fewer pixels of the low resolution image, the amount of calculation may be reduced and the processing speed for generating the holographic image may be increased.

Abstract: Provided are an apparatus and method for performing a Fourier transform. A method of performing a Fourier transform may include generating intermediate data by performing a one-dimensional fast Fourier transform (1D FFT) on data in a column direction, storing the intermediate data in a cell array in the column direction, reading out the intermediate data from the cell array in a row direction; and generating final data by performing a 1D FFT on the read-out intermediate data.
