Abstract (in Japanese) (See Japanese page) 
(in English) The pixels in image sensors and displays are placed at lattice positions.
The images handled by these devices are finally `seen' by our eyes, which perceive the jaggy at the edge.
Conventional approaches for this problem, such as increasing resolution and smoothing, cannot completely solve this problem, which is a critical factor for more clear images, since the jaggies are composed of a pair of certain pixels.
In this paper, we propose an idea for this problem using the nonperiodic pixel placement which based on bit reversal, and compare the characteristic of jaggy with traditional square lattice pixel placement.
This new pixel placement can also eliminate striped nonuniform distribution which occurs with stretch vertically or holizontally.
