摘要

针对近眼显示系统存在数据传输带宽过高的问题,构建多尺度金字塔模型实现人眼视觉区域的多分辨率显示,将人眼视觉区域空间变化率的特性应用到数据传输的过程中;根据多尺度金字塔模型设计面向近眼显示系统的微显示控制器,实现了对视频图像的编解码处理,并在分辨率为1600×1600×3的全彩高清硅基有机发光二极管(OLED)微显示器上验证控制器的可行性。实验结果表明,基于多尺度金字塔的多分辨率图像传输算法符合人眼的直观感受,较好地去除了下采样过程中出现的边界线效应,有效降低了数据的传输带宽,能够满足近眼显示领域对微显示器实时渲染性能的要求。

Abstract

With an aim to overcome the problem of excessive data transmission bandwidth in near-eye display systems, this study proposes a multiscale pyramid model to realize multi-resolution display in the human visual region. We apply the characteristics of the spatial change rate of the human visual region to the data transmission process. Based on a multi-scale pyramid model, a microdisplay controller for the near-eye display system is designed, realizing the encoding and decoding processes of the video image. The feasibility of this controller is verified on a 1600×1600×3 full-color high-definition OLED-on-silicon microdisplay. Experimental results show that the multi-resolution image fusion algorithm based on a multi-scale pyramid meets the visual perception requirements of human eyes and solves the boundary line effect appearing in the subsampling process, effectively reducing the data transmission bandwidth. The proposed algorithm satisfies the requirements for the real-time rendering performance of the microdisplay in the near-eye display field.
