“…In this step, three views are decided by the values of every position (i, j) on the mapping table, because the decimal portion indicates the current view number by (7). In the sub-pixel multiplexing based on the weighted view-overlay step, each upscaled sub-pixel value of the three views are, respectively, multiplied by each weighted value in accordance with (2) and then summed to decide the final sub-pixel value, where each weighted value is calculated by the decimal fraction of the mapping table values as previously illustrated. It is noted that every sub-pixel is not interpolated throughout these two steps but only sub-pixels designated by the mapping table are interpolated to generate the final sub-pixel multiplexed image.…”

“…However, there are still technical issues to successfully commercialise the glasses‐free 3DTV in various markets including the commercial area. When it comes to the autostereoscopic 3D display, in most cases the lenticular lens is placed on the 4K LCD panel, mostly slanted to resolve the Moiré‐like black band and degradation of image resolution in only the horizontal direction [1, 2]. However, because of the slanted lenticular lens, one or more views are positioned onto a single sub‐pixel, which may result in an increase of crosstalk.…”

A sub-pixel multiplexing algorithm for generating multi-view images on an autostereoscopic three-dimensional (3D) display at high speed is proposed. Generally, sub-pixel multiplexing in an autostereoscopic 3DTV system is to assign R, G, B colour sub-pixels of multiple view images at the proper position on the display such that a proper view image can be seen in accordance with the viewer's position. The upscaled sub-pixel multiplexing algorithm proposed is composed of bilinear upscaling and a weighted view overlay. Even though upscaling multiple view images requires too much resources and increases system complexity, the proposed algorithm can significantly reduce complexity from an implementation point of view while providing high-quality 3D views. Specifically, the advantage of the proposed weighted view-overlay technique is that several overlaid view images decide the colour value of the sub-pixel, which results in increasing the subjective quality of view images. Through an experiment, it is confirmed that the image quality of generated multi-views with the proposed algorithms is notably better than the existing simple techniques.

“…This approach can adjust the viewing angle of the lenticular display by simply changing the mapping matrix. In order to address misalignment due to the subpixel mapping, a floating viewpoint image is synthesized by using stereo images and the corresponding depth maps [44].…”

Stereoscopic viewing of 3D content brings with it a variety of complex perceptual quality issues. For the percept of depth to be convincing, consistent, and comfortable, many parameters throughout the imaging pipeline must to be matched correctly. However, tradeoffs are inevitable for practical reasons, which may lead to various distortions. This paper reviews the issues from an engineering perspective, addressing in particular depth issues, multiview issues, display issues, viewer-specific issues, as well as possible measurements for the overall 3D quality of experience (QoE).

“…Furthermore, many researchers have been studying 3-D display implementation using LCDs for near-future applications, which require even higher frame rates and, thus, faster transition times. 2,3 To improve display quality and extend into new applications, new driving technologies have been developed. [4][5][6][7] Among them, the overdrive technology that was developed in the early 1990s contributed toward the success of the LCD television ͑TV͒ business by significantly reducing the response times.…”

New overdrive technology for liquid-crystal displays with a simple architecture

We propose a new technique to extract overdrive ͑OD͒ values that are indispensable to improve response characteristics of liquidcrystal displays. We show the relation among an OD value ͑D OD ͒, a previous frame data ͑D PF ͒, and a current frame data ͑D CF ͒ can be expressed very well by a third-order polynomial. To make the implementation of the OD technology to be simple, we propose to create a base line that is expressed by the third-order equation and to linearly shift it according to D PF . Our proposed method does not need the large size lookup tables ͑LUTs͒, whereas the conventional OD technology requests huge LUTs. Thus, our method can be easily implemented by very small circuits, which enables a low-cost solution. Only six measurements in our method are sufficient to obtain OD values of all the transition, whereas the conventional one wants 256 measurements. We investigate the best position of the base line and show how small the deviation from optimum values is. We prove that the proposed OD technology enables a low-cost implementation, high productivity, and high performance.
