QHD (quadruple HD: 3840*2048 pixels) projector which displays ultra-high definition images closing to visual limitation

摘要

The authors proposed an ultra-high definition image format (QHD: Quadruple HD), which provides double the resolution of HDTV image format in both lengthwise and crosswise Based on this format, we developed QHD camera, which captures each color of RGB by single chip, and QHD projector, which displays each color of RGB by single chip. In this paper, we would like to describe the outline of QHD projector, and the outline and the result of a subjectivity evaluation experiment of the QHD image carried out using the still-frame picture.
