Abstract:
A holographic display device and method of generating a hologram using redundancy of 3D video are disclosed. A storage unit stores the hologram of a previous 3D image frame. A control unit generates an update map indicating an update required 3D point among 3D points included in a current 3D image frame based on the current 3D image frame and the previous 3D image frame and modifies the update map to further include information indicating the update of a 3D point related to the update required.
