Abstract

The pixels in the conventional image systems are located in lattice places, that cause the jaggy in the image, which often cause the severe defect in the image quality. The conventional approaches to overcome this jaggy problem are such as the increased number of pixels and anti-aliasing, however, the number of pixels is limited by the physical pixel size and the quantity of the image information, while the anti-aliasing intrinsically causes the blurred image. The authors have been proposing and evaluating the image systems with pseudorandom pixel placement to decrease the effect of the jaggy. In this report, we propose the jaggy evaluation method using discrete Fourier transform, as well as the evaluation of the jaggy elimination by pseudorandom pixel placement.
