Problems solved by technology

However, this is not easy to achieve because autostereoscopic displays showing two viewpoints as well as multi-viewpoint displays have the aforementioned contradictory characteristics
[0006] In addition, a multi-view display can provide a wider viewing angle than an autostereoscopic display that displays two viewpoints, however, this results in a 3D image that can only be viewed without distortion within a limited viewing angle and certain distances
Multi-view display also does not allow 3D images to be viewed satisfactorily when the user tilts his head or lays down at a certain angle to view the display
These viewing limitations would be a significant disadvantage compared to existing 2D displays and therefore, as 3D displays, multi-view displays would encounter difficulties in commercialization

Embodiment Construction

[0035] One or more embodiments illustrated in the drawings will now be set forth in detail, wherein like reference numerals refer to like elements throughout. In this regard, embodiments of the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Accordingly, the embodiments are merely described below, by referring to the figures, to explain aspects of the present invention.

[0036] Embodiments may relate to an image display system and method that can track the position of the user's left eye / right eye to determine viewpoint information of an image viewed by the user. In one or more embodiments, active sub-pixel rendering is used based on the determined viewpoint information to provide A 3D image with no or limited chroma-luminance interference or distortion with a three-dimensional (3D) effect. By performing sub-pixel rendering instead of just pixel rendering, the number of displayed views is increased...

Abstract

Provided are a high density multi-view image display system and method based on active sub-pixel rendering. The image display system may perform a rendering with respect to a viewpoint image in a pixel unit, using a viewpoint varying based on a position of left / right eyes of a user.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2009-0105855 filed with the Korean Intellectual Property Office on November 4, 2009, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] One or more embodiments relate to a high-density multi-view image display system and method using active sub-pixel rendering. Background technique [0003] In order to effectively implement a three-dimensional (3D) image, images having viewpoints different from each other may generally need to be viewed by a user's left / right eye, respectively. In order to achieve this 3D image without the use of filters (e.g. without the user having to wear a filter to view the 3D image), the 3D image may need to be spatially divided based on viewpoint, which is known as an autostereoscopic display . The viewpoint may represent a viewing direction of generated light from which a specific view of a 3D image may be seen, so that i...
