What is an eye-tracking function?
Eye-tracking is a function that displays a 3D image that corresponds to a viewer’s viewing position, thus improving the quality of the 3D image. An eye-tracking integral 3D display with this function is composed of a camera that tracks the viewer’s viewing position, an integral 3D display, and a high-performance computer to generate an elemental image array.
First, the image captured with a camera is analyzed and the viewer’s viewing position is calculated. Next, the computer generates an elemental image array that corresponds to the viewing position. Last, the integral 3D display displays a 3D image.
As compared with normal integral 3D displays, eye-tracking integral 3D displays are able to broaden the depth range and the viewing zone. Broadening of the depth range can be realized by using a lens array with a long focal length and displaying light rays with a high density in a narrow range. However, in this case, the viewing zone will narrow. Nevertheless, a 3D image displayed from the viewer’s viewing position allows for the securing of a wide viewing zone.
