This study predicts the Helmholtz–Kohlrausch effect of natural images under various ambient lighting conditions. The proposed prediction equation was obtained by incorporating the experimental values of International Display Workshop (IDW) 19 into the previous values obtained by IDW’18 to improve the accuracy of previous prediction equation.
