Apparatus and method for generating hologram based on human visual system modeling

A method for generating a hologram image corresponding to a three-dimensional object, comprising:

• focusing light emitted from the three-dimensional object;
• detecting the light;
• determining a confusion circle size threshold value corresponding to information of a sensor detecting the light and information of a lens focusing the light;
• determining a position of a plurality of planes passing through the three-dimensional object based on the confusion circle size threshold value;
• obtaining object information of the three-dimensional object of each of the plurality of planes;
• and
• generating a hologram image of the three-dimensional object based on the object information.

An apparatus for generating a hologram based on human visual system modeling, comprising:

• a lens configured to focus light emitted from a three-dimensional object:
• a sensor configured to detect the light;
• an object information obtaining unit configured to determine a confusion circle size threshold value corresponding to information of the sensor and information of the lens, determine a position of the three-dimensional object closest to the lens as a position of a first plane, determine a first focal length of the lens corresponding to the position of the first plane, determine a position of at least one second plane that is different from the first plane based on the first focal length and the confusion circle size threshold value, and obtain object information of the three-dimensional object of each of the first plane and the at least one second plane;
• and
• a hologram image generating unit configured to generate a hologram image of the three-dimensional object based on the object information.
