Embodiment Construction

[0019] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order not to obscure the invention.

[0020] Embodiments of the invention relate, among other things, to a display controller for controlling a display screen of a display system. The display controller includes an image receiver configured to receive image data from a source, where the image data includes a first image and a second image. The display controller includes a first window controller coupled to the image receiver and configured to receive a first image from the image receiver and scale the first image according to parameters of the display screen to generate a scaled first image. The display controller incl...

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.

Description

technical field [0001] The present invention relates generally to display systems, and more particularly to efficient autostereoscopic support using display controller windows. Background technique [0002] Autostereoscopic is a method of displaying stereoscopic images (eg, adding binocular perception of three-dimensional (3D) depth) without using special helmets or glasses on the part of the viewer. Single channel images are perceived by the viewer as being two-dimensional (2D). Autostereoscopic is also called "glasses-free 3D" or "glasses-free 3D" because you don't need to go to the helmet. There are two broad approaches currently used to accommodate motion parallax and wider viewing angles: (1) eye tracking and (2) so that the display does not need to sense multiple views of where the viewer's eyes are located. [0003] Examples of autostereoscopic display technologies include lenticular lenses, parallax barriers, volumetric displays, holographic and light field display...
