Paper Abstract

The purpose of this study can be divided into two descriptions. First, we investigated perceived brightness contrast to varied surround luminance levels from dark to over-bright conditions by measuring psychophysical data using magnitude estimation. As a result, the perceived brightness contrast increases until surround changes from dark to average, it decreases from average to over-bright. Second, so obtained experimental results are compared with brightness contrast estimates of CIECAM028 and MobileCAM9 and we refined a surround factor c and brightness correlate Q of CIECAM02. Consequently, the refined results appear matched to brightness contrast. A Pearson correlation between the refined CIECAM02 prediction and the visual results was 0.95.
