| Abstract(in English) | To perceive shape from shading, we need the information about the direction of illumination. It has been reported that we perceive shape from shading with the "light from above assumption". However we often face the situations in which light comes from bottom or other directions. In these situations, we must extract the information about the direction of illumination from the visual image for perceiving shape from shading. In this research, we investigated how we estimate the direction of illumination from the visual information. The results showed that the information about the direction of illumination was extracted from the surrounding visual stimuli and the effect decreased with the distance. In addition when the explicit visual information about the direction of illumination was available, the "light-from-above assumption"still worked. These facts indicate that the information about the direction of illumination indicated by visual stimulus is effective in a local area for the perception of shape from shading. |
