Abstract

The recognition limit of brightness difference in the visual system of human has not been studied system-atically. In this paper, endeavor to calculate surround adapted Weber-Fechner fractions based on the crispening effect was added to the traditional Weber-Fechner fractions. It is found that surround adapted fractions have reduced to 1/3 of the traditional fractions. As compared with Breitmeyer's experiments, the presented result is a reasonable one. It can be used as some guide to design the digital display system when a designer needs to decide bit count of digital signal in considering of the limit of brightness level, and as the inspection tool of display manufacturing of brightness smear, defect, and so on.
