| Abstract(in English) | We investigated the effects of blur adaptation on the transfer characteristics of a spatial vision. We measured and compared the percentage of correct answers for Snellen letter blurred by an ametropy-simulated filter in each adaptive state. As a result, it was found that the percent correct is significantly improved when the identical blur filter is applied to the stimuli for adaptation. This indicates that the inverse filter of eye optics which causes the retinal image blur is acquired by the blur adaptation in the visual system so as to decrease the perceived blur. Such compensation effect occurs also against the blur filter with non-linear phase characteristics. We therefore concluded that the classical local contrast adaptation is unlikely as a neuronal mechanism underlying the blur compensation effect. |
