The aim of this research is to derive illuminant-independent type of HDR imaging modules which can optimally multispectrally
reconstruct of every color concerned in high-dynamic-range of original images for preferable cross-media
color reproduction applications. Each module, based on either of broadband and multispectral approach, would be
incorporated models of perceptual HDR tone-mapping, device characterization. In this study, an xvYCC format of HDR
digital camera was used to capture HDR scene images for test. A tone-mapping module was derived based on a multiscale
representation of the human visual system and used equations similar to a photoreceptor adaptation equation,
proposed by Michaelis-Menten. Additionally, an adaptive bilateral type of gamut mapping algorithm, using approach of
a multiple conversing-points (previously derived), was incorporated with or without adaptive Un-sharp Masking (USM)
to carry out the optimization of HDR image rendering. An LCD with standard color space of Adobe RGB (D65) was
used as a soft-proofing platform to display/represent HDR original RGB images, and also evaluate both renditionquality
and prediction-performance of modules derived. Also, another LCD with standard color space of sRGB was
used to test gamut-mapping algorithms, used to be integrated with tone-mapping module derived.
