Abstract: A method for processing a three-dimensional holographic image includes obtaining depth images from depth data of a three-dimensional object, dividing each of the depth images into a predetermined number of sub-images, obtaining interference patterns of computer-generated hologram (CGH) patches corresponding to each of the sub-images by performing a Fourier transform to calculate an interference pattern in a CGH plane for object data included in each of the sub-images, and generating a CGH for the three-dimensional object using the obtained interference patterns of the CGH patches.

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.
