Abstract
The image systems have been developing toward the purpose of representing 'clear' images. The regular lattice pixel placement in the conentional image systems intrinsically have the problem of jaggies on diagonal line that may result in severely decrease the image clarity. The authors have been proposing and discussing the image systems with the psudoramdomly placed pixel for eliminating the jaggies in images. The clarity of the represented images by the psudorandom pixel placement deeply depends on the pixel configuration parameters, and the optimization of these parameters are not clarified. In this paper, it is described that the subjective experiments for optimizing three pixel configuration parameters; the size of luminescent area, the area displacement within the pixel, and the light diffusion from the area.
