視覚特性を考慮したCRTラスタモアレパターンのシミュレーション : 情報入力,情報ディスプレイ

抄録

Market place of high resolution, wide screen color CRTs for home use TVs is expected to increase drastically. In these tubes, moire patterns generated by an interaction between raster scan beams and shadow mask apertures damage picture quality. A computer simulation of the raster moire patterns which appear on slotted mask CRTs are performed, taking into consideration the low pass filter characteristics and light difference threshold characteristics of human eyes. The simulated moire patterns coincided well with the visual observations. Also moire contrast was evaluate to find perceptivity of the moire patterns.
