Spatio-Temporal Response of Color Vision Based on Parallel Pathway

Abstract

Characteristics of vision, whose are spatio-temporal frequency response, spatio-temporal transient phenomena, phase correlation between two eyes to brightness channel and chromatiness channel of vision, and movement perception of chromaticness channel, were measured by psychophysical experiment. We found that experiment results can be explained well by parallel pathway of color vision. Especially, the phase of temporal dominant system in r-g channel has inphase to r-component of spatial dominant system and counterphase to g-component.
