Abstract
Disclosed herein is an apparatus for reproducing a hologram image. The apparatus may include a holographic display module for reproducing a digital hologram, a background display module for reproducing a background image, and a combiner for selecting the background image in consideration of the depth map of the digital hologram and reproducing a hologram image synthesized by combining the selected background image with the digital hologram.
Claims17
An apparatus for reproducing a hologram image, comprising:
- a holographic display module configured to reproduce a digital hologram;
- a background display module, including a background display, and configured to reproduce a background image;
- and
- a combiner configured to select the background image based on a depth map of the digital hologram and reproduce a hologram image that is synthesized by combining the selected background image with the digital hologram,
- wherein the background display is configured to move forwards and backwards along an optical path, and a depth of the background image is adjusted based on a location of the background display,
- wherein, when a display plane of the holographic display module corresponds to an XY-plane, the holographic display module is configured to emit a digital hologram in a z-axis direction,
- wherein the background display module is configured to emit light in the z-axis direction, and
- wherein a background image is displayed in the z-axis direction through the combiner.

A method for reproducing a hologram image, comprising:
- reproducing, by a holographic display module, a digital hologram;
- reproducing, by a background display module which includes a background display, a background image;
- and
- selecting, by a combiner, the background image based on a depth map of the digital hologram and reproducing, by the combiner, a hologram image that is synthesized by combining the selected background image with the digital hologram,
- wherein the background display is configured to move forwards and backwards along an optical path, and a depth of the background image is adjusted based on a location of the background display,
- wherein, when a display plane of the holographic display module corresponds to an XY-plane, the holographic display module is configured to emit a digital hologram in a z-axis direction,
- wherein the background display module is configured to emit light in the z-axis direction, and
- wherein a background image is displayed in the z-axis direction through the combiner.
