| Abstract |
This paper reports a comparative study on evaluating the performance of
six display characterization models applied to mobile displays of four Apple
iPhones belonging to three different models (3GS, 4 and 4S). The character-
ization models evaluated include three PLCC (Piecewise Linear interpolation
assuming Constant Chromaticity coordinates) models, the PLVC (Piecewise
Linear interpolation assuming Variation in Chromaticity) model, Tamura-
Tsumura-Miyake masking model with one principle component (MM) and
modified masking model with two principle components (MMM). The results
showed that PLCC3, MM and MMM models are among the best models for
all tested iPhone displays. Our study also revealed that different models are
ranked differently on two iPhones of the same model (iPhone 4), which suggests
that the intra-model consistency may be an issue for smart phone displays. |
