The ultimate aim of this study is to elucidate the mechanism inducing perceptual filling-in from the viewpoint of spatio-temporal frequency characteristics in vision. In our preliminary study (yokota, VSS 2005), we found that incomplete fixation distributes filling-in time. Furthermore, that we can see nothing by restraining eye movement artificially is well known. Therefore, we can consider that time to filling-in is influenced by eye movement. Although it has been recently reported that eye movement influences the filling-in occurrence (Matinez-Conde, neuron 2006), the relation between eye movement and the filling-in time has rarely been reported.
For this study, we measured the filling-in time for three subjects, for four surrounding textures, with simultaneous recording of eye movement. The results show that the filling-in time correlates the standard deviation of the distance from the eye position to the fixation point. Furthermore, we found relatively strong correlation between the filling-in time and the power of high frequency range between 50–200 [Hz] in the eye movement, though the correlation of the power of low frequency range between 10–50 [Hz] is not so high. Thus we suppose that filling-in is inhibited by small involuntary eye movement.
