Abstract: An approach is provided for efficient autostereoscopic support by using a display controller for controlling a display screen of a display system. In one example, the display controller includes the following hardware components: an image receiver configured to receive image data from a source, wherein the image data includes a first image and a second image; a first window controller configured to receive the first image from the image receiver and to scale the first image according to parameters of the display screen in order to generate a scaled first image; a second window controller configured to receive the second image from the image receiver and to scale the second image according to the parameters of the display screen in order to generate a scaled second image; and a blender component configured to interleave the scaled first image with the scaled second image in order to generate a stereoscopic composited image.
