Many researches concerning a visual acuity are reported. The Landolt ring is used as the typical index. The value of a visual acuity shows a variation according to the measurement condition. On the other hand, there are many researches about the spatial frequency response or MTF(Modulation Transfer Function) of eye. From the point of view whether the detail of the pattern can be identified, the MTF method is more general. However, a theoretical paper for a concrete pattern is not reported. It is necessary to establish a quantitative evaluation to identify an arbitrary pattern under the various conditions. In this paper, a cognitive limit of visual system is descrived from the theory and the experimental values. The pattern visible distance is derived from the wave-form analysis. It became clear that the experimental results which are made by visual angle method are presumed considerably well by the equivalent band-pass method. If the modulation transfer function is changed a little, a very big effect is exerted on the pattern visible distance.}, pages = {55--62}, title = {視覚系の認知限界}, volume = {17}, year = {1994} }
