WebFeb 21, 2006 · It was observed that at high luminances the temporal resolution of object identification remained unchanged at a wide range of contrasts and sizes. However, the temporal resolution was reduced at low contrasts, small sizes, and low luminances. Further, for facial stimuli processing, speed was found to be lower than for character information. WebMay 1, 2005 · Therefore, at high luminance, all cells are active for a high level of visual acuity. At low luminances, only cells sensitive to that level of luminances are active, and because they are distributed randomly, the retinal mosaic is coarser; thus, a lower level of visual acuity is achieved ( 12 ).
