Abstract

Images on the retina change rapidly during saccades. The visual system integrates clear images before and after saccades to produce a stable perception of the outside scene. It is said that during saccades the visual system is suppressed to eliminates the smeared images, which may disturb integration of the retinal images.¹⁾ It has not been well understood how the visual system eliminate the smeared images. Luminance and chromatic channels in the visual system seem to play different roles to perceive the outside scene.²⁾ If the saccadic suppression is useful to integrate images, luminance and chromatic channels may be suppressed differently during saccades. In this report, we measured spectral sensitivity functions by the increment threshold method during saccades and fixation in order to clarify the effects of saccadic suppression on luminance and chromatic channels.^3),4)
