Method and apparatus for transmitting hologram data in binocular holographic display

An apparatus for transmitting hologram data, the apparatus comprising:

• a memory storing one or more instructions;
• and
• one or more processors executing the one or more instructions stored in the memory,
• wherein the processor
• obtains left-eye gaze information and right-eye gaze information on a viewing window plane of a binocular holographic display based on pupil images of a user of the binocular holographic display;
• determines a left-eye hologram region and a right-eye hologram region on a hologram plane of the binocular holographic display based on the left-eye gaze information, the right-eye gaze information, and distance information between the viewing window plane and the hologram plane;
• and
• creates transmission hologram data corresponding to one binocular hologram region including an overlap hologram region, in which the left-eye hologram region and the right-eye hologram region overlap each other, based on input hologram data,
• wherein the processor determines a left-eye gaze reaching point and a right-eye gaze reaching point of the user on the hologram plane based on the left-eye gaze information, the right-eye gaze information, and the distance information between the viewing window plane and the hologram plane;
• and
• determines the left-eye hologram region based on the left-eye gaze reaching point and preset left-eye hologram resolution information and determines the right-eye hologram region based on the right-eye gaze reaching point and preset right-eye hologram resolution information.

A method for transmitting hologram data in a binocular holographic display, the method comprising:

• obtaining left-eye gaze information and right-eye gaze information on a viewing window plane of the binocular holographic display based on pupil images of a user of the binocular holographic display;
• determining a left-eye hologram region and a right-eye hologram region on a hologram plane of the binocular holographic display based on the left-eye gaze information, the right-eye gaze information, and distance information between the viewing window plane and the hologram plane;
• and
• creating transmission hologram data corresponding to one binocular hologram region including an overlap hologram region, in which the left-eye hologram region and the right-eye hologram region overlap each other, based on input hologram data,
• wherein the one binocular hologram region includes the overlap hologram region in which the left-eye hologram region and the right-eye hologram region overlap each other, a non-overlap hologram region of the left-eye hologram region, and a non-overlap hologram region of the right-eye hologram region,
• wherein the creating transmission hologram data comprises:
• creating hologram data corresponding to the overlap hologram region based on input hologram data for at least one of a left eye or a right eye;
• creating hologram data corresponding to the non-overlap hologram region of the left-eye hologram region based on input hologram data for the left eye;
• and
• creating hologram data corresponding to the non-overlap hologram region of the right-eye hologram region based on input hologram data for the right eye.
