摘要： Provided is a method for performing a Fourier transformation for generating a computer-generated holographic (CGH) image. The method includes generating first intermediate data by performing a first FFT calculation that relates to coordinates of a pupil of a user with respect to input image data; generating second intermediate data by calculating a light concentration effect correction term for correcting a light concentration effect occurring at the pupil of the user and multiplying the first intermediate data by the light concentration effect correction term; and performing a second FFT calculation that relates to the coordinates of the pupil of the user with respect to the second intermediate data.
