Abstract

Because the retinal cone mosaic samples an image only at discrete locations, our continuous visual percept must arise from a spatial reconstruction process. How this process combines information from the three cone types is presently unclear. To investigate, we asked whether luminance information can modify the visual system's reconstruction of signals from the S cones. In Experiment 1, we used a matching paradigm to measure the effect of luminance information on filling-in at the foveal tritanopic area. In Experiment 2, we asked whether luminance information can modify the splotchy low-frequency alias seen when an observer views fine S cone gratings.
