Abstract: An apparatus and method for processing a holographic image. The apparatus calculates a first calculation result with respect to an image for the left eye and a first calculation result with respect to an image for the right eye and stores the results at different memory addresses of a storage. Thereafter, the apparatus calculates values of a waveform of light to be modulated by a spatial light modulator by performing a second calculation that uses all of the first calculation results stored in the storage. An image window of the image for the left eye and an image window of the image for the right eye are spatially separated from each other by the apparatus in a viewing window of a hologram image reproduced via the spatial light modulator.

Abstract: 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.
