Three-dimensional auto-focusing display method and system thereof

A three-dimensional (3D) auto-focusing display method, comprising:

• providing an image;
• executing an eye-tracking step on the image to obtain focal point coordinates (x1, y1) of viewers of the image;
• mapping the focal point coordinates (x1, y1) of viewers to a coordinate location of a display to obtain display coordinates (x2, y2) for defining the coordinate location of the display corresponding to a depth diagram of the image;
• determining a region where the image is located by using the display coordinates (x2, y2) as an input parameter and by use of the depth diagram of the image;
• determining whether the image is three-dimensional (3D) stereoscopic images according to the region where the image is located, and executing a depth map step to revise the 3D image based on the image and a plurality of depth data of the region to reflect the display coordinates (x2, y2) as a focused image;
• and
• outputting the revised focused image to the display to display 3D stereoscopic images on the display.
