By operating on a binary black and white image with on ordered dither method, it appears, to our visual senses, to become clearer because of a pseudo halftone. This is because when we don't notice of all the details of the images, instead we see from a more global stand point. We investigated our one-dimensional visual information processing model. We presented a theory and experimented results for a layered model which extended external world, retina and brain. This paper represent the restoration image of the pulse density modulation of two-dimensional visual information processing model and we be able to estimate the subjective good and bad of the pulse density modulated image by approximated degree, further we are clear the validity of this model.
