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.

“…1. The reduction of pixel size also decreases the size of jaggies, however, it is hard to completely eliminate the jaggies "perceived" by our eyes, since our eye system has a high sensitivity for perceiving the small steps forming jaggies, so called the Vernier accuracy [1,2].…”

Abstract:The pixels in the conventional image sensors are placed at lattice positions, and this causes the jaggies at the edge of the slant line we perceive, which is hard to resolve by pixel size reduction. The author has been proposing the method of reducing the jaggies effect by arranging the photo diode at pseudorandom positions, with keeping the lattice arrangement of pixel boundaries that are compatible with the conventional image sensor architecture. In this paper, the author discusses the design of CMOS image sensor with pseudorandom pixel placement, as well as the preliminary evaluation of the fabricated CMOS image sensor.
