When we see a binary black and white image, it appears, to our visual sense, to become clearer because of a pseudo halftone. We presented a theory and experimental results for layered model, which extend external world, retina and brain of the visual model, the equivalence approximation method. This paper propose the fixed equivalence approximation method, which modify the equivalence approximation method, it is difficult to find window size. We obtain experimentally the reconstructed images, the measure of approximation of density four division method, ordered dither method, simple two value method and least mean error method. The measure of approximation presents the objective estimation scale to coincide with the subjective estimation of the four modulation images by the fixed equivalence approximation method with the fixed window size and fixed approximation. We present the image estimation method, which is no significant difference between equivalence approximation method and fixed equivalence approximation method.
