Abstract (in Japanese) (See Japanese page) 
(in English) When jitter is attached to a regional screen beyond the visual spatial frequency response, banding (a transversal line) occurs. Therefore we confirmed the banding appearance when we gave screen as carrier with the single frequency, and jitter as side band by experiment. The following became clear with screen frequency 69cpd, jitter frequency 5.2cpd and sensitivity by 2AFC. a) The 2nd order harmonics or higher decreases the banding recognition rate. b) The contribution of cross term within carrier and side band is big, and strongly suggested the presence of nonlinearity before V1. As a result, moiré is regarded as the main factor of the banding.
