The conventional image systems have been developed in order to enhance the quality of the image representation. Jaggy appearing at the edge of a slant line are, however, easily perceived by human eyes, which often severely defect the ‘perceived’ image quality, because of the spatial perceive characteristics of our eye system. Although the size of the jaggy can be reduced by reducing the pixel size, it is hard to completely eliminate the perceived jaggy by using the conventional lattice pixel placement, since our eye system is sensitive enough to perceive such jaggy.
In this paper, we describe the basic concept of the pseudorandom pixel placement to reduce the jaggy effect, and discuss the relation of jaggy reduction effect and the pixel structure characteristics, in terms of the fill factor and the number of pixel types.
