Image-acquisition-and-display device architecture without directional singularity using pseudorandom pixel placement

Abstract

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.
