Method for setting three-dimensional image display system

A method for setting a three-dimensional image display system including a display panel configured to display a parallax image including a right-eye image and a left-eye image, an optical panel configured to define a traveling direction of light for each of the right-eye image and the left-eye image, a reflective plate configured to reflect the right-eye image and the left-eye image with the traveling direction of light being defined, a first camera configured to capture a first image including an image of an area expected to include a face of a user of the three-dimensional image display system, a first controller configured to detect a position of at least one of eyes of the user as a first position based on the first image, a second controller configured to generate the parallax image including the right-eye image and the left-eye image based on a first distribution of a first parameter and the first position, a third controller configured to calculate a second distribution of the first parameter, and a first communicator configured to communicate with an external device, the external device including an external camera including a second camera configured to capture a second image and a second communicator configured to communicate directly or indirectly with the first communicator, the method comprising:

• moving the second camera to a position to allow the parallax image reflected from the reflective plate to be captured;
• detecting the position of the second camera as a second position based on the first image;
• sequentially displaying a plurality of test images on the display panel, and sequentially capturing the plurality of test images reflected from the reflective plate with the second camera to obtain a plurality of second images;
• calculating the second distribution based on the plurality of second images and the second position;
• and
• replacing the first distribution with the calculated second distribution.
