Abstract
A method of modulating a depth of a hologram, the method includes: obtaining hologram data; determining a scale factor based on a 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.
Claims18
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.
