    Abstract: A three-dimensional (3D) image providing method and apparatus is provided. The 3D image providing method includes detecting an eye location of a viewer and providing a 3D image based on the detected eye location, in which the providing of the 3D image includes determining an image pixel value corresponding to a display pixel of a display panel, determining a luminance weight corresponding to the display pixel based on a ray direction of a ray output from the display pixel and the detected eye location, applying the luminance weight to the image pixel value corresponding to the display pixel, and outputting, through the display pixel, the image pixel value with the luminance weight applied thereto.
