1. A method of modulating a depth of a hologram, the method comprising:
obtaining hologram data;
determining a scale factor based on an actual hardware specification of a holographic display to display a three-dimensional (3D) hologram image in a space by using the hologram data; and
modulating depth information of the hologram data based on the scale factor,
wherein the modulating of the depth information of the hologram data comprises modulating the depth information of the hologram data by using a neural network trained to correct depth distortion due to a difference between an assumed hardware specification assumed when generating the hologram data and the actual hardware specification of the holographic display.
