This produces haze into the view, and color saturation is physically decreased. However, our previous psychophysical study revealed that people maintain normal colorfulness perception under haze vision. Here, in order to elucidate this saturation compensation mechanism in the brain, we investigated neural activities associated with colorfulness perception under haze vision induced by haze filters using fMRI. METHODS: Thirteen young healthy participants (age range: 21-38 years old) were included in the study. We used 5 different natural scene images with 4 saturation levels as stimuli. The experiment consisted of 5 haze blocks that participants viewed stimuli though haze filters and 5 control blocks without the filters. In both conditions, the participants evaluated the colorfulness of stimuli. RESULTS & CONCLUSIONS: Results showed that the participants differed in the ability to correct saturation under haze vision, and the individual differences in saturation correction was associated with activities in the supplementary motor cortex, the middle frontal gyrus, and the caudate. The current study is the first to identify the brain regions associated with saturation correction for haze vision., 14th annual Asia Pacific Conference on Vision}, title = {Cortical areas related to saturation correction for haze vision}, year = {2018} }
