疑似的な不規則画素配置をもつ方向特異性のない撮像・表示素子構成の基礎検討 (論文小特集 画像の処理と符号化)

金沢大学大学院自然科学研究科情報システム金沢大学工学部Conventional image display devices and image acquisition devices consist of regularly located pixels. The pixels are located in a matrix for ease of implementation. Matrix placement of pixels intrinsically has directional singularity in the representation of images. The clarity of represented images is significantly dependent on the directions that objects in the image, such as lines, are facing. For example, horizontal lines are perfectly represented by matrix pixels, while the slanted lines have the jagged edges. We developed a pseudorandom pixel placement architecture that has no directional singularity in the representation of images, and we evaluated its characteristics and layout implementation
