A range of the reproducible color, i.e., color gamut, of the conventional display devices such as CRTs (cathode ray tubes) and LCDs (liquid crystal displays) is sometimes insufficient for reproducing the natural color of an object through color imaging systems. In this paper, a six-primary color display is developed to reproduce the expanded color gamut, by using two conventional RGB projectors...

As the application of AMOLED becomes more and popular, technologies are needed to implement color management gamut mapping. The paper proposes a mapping method adjust temperature. We add additional white achieve control temperature when implementing tuning flow. original is also separated into RGW/RWB/WGB perform multiply 3x3 matrix iterate its XYZ calculation respectively.

Six techniques for mapping the colors of an image into the gamut of printable colors were compared. Six pictorial scenes were used in two psychophysical experiments, one to test accurate reproduction and one to test preferred reproduction. A new contrast-enhancing algorithm was found to give more favorable reproductions than several gamut-mapping techniques described in the literature. This alg...

Masato Sakurai Rodney L. Heckaman Stacey E. Casella Mark D. Fairchild Takehiro Nakatsue Yoshihide Shimpuku Abstract — The effect of varying the color gamut of an extended-gamut LCD on color appearance and preference was measured psychometrically in two experiments at each of two separate laboratories over a representative set of 10 images each. The first experiment measured the effect of color ...

We present a new efficient hueand edge-preserving spatial color gamut mapping algorithm. The initial computation of the algorithm is to project all out-of-gamut colors to the destination gamut boundary towards the center of the gamut. Based on this spatially invariant hue-preserving clipping of the image, we construct a greyscale map indicating the amount of compression performed. This map can ...

This paper proposes a new approach for color transfer between two images. Our method is unique in its consideration of the scene illumination and the constraint that the mapped image must be within the color gamut of the target image. Specifically, our approach first performs a white-balance step on both images to remove color casts caused by different illuminations in the source and target ima...

An ink separation algorithm is introduced for printing with 6 to 9 inks. A spectral gamut mapping algorithm is also introduced that projects an input reflectance onto the manifold of the printer spectral gamut space The ink separation, which is finding the best ink combination to reproduce a given reflectance, is done by applying an interpolation between printer gamut points neighboring a proje...

We test a number of the leading computational color constancy algorithms using a comprehensive set of images. These were of 33 different scenes under 11 different sources representative of common illumination conditions. The algorithms studied include two gray world methods, a version of the Retinex method, several variants of Forsyth's gamut-mapping method, Cardei et al.'s neural net method, a...

ABSTARCT With the advent of digital images the problem of keeping picture visualization uniformity arises because each printing or scanning device has its own color chart. So, universal color profiles are made by ICC to bring uniformity in various types of devices. Keeping that color profile in mind various new color charts are created and calibrated with the help of standard IT8 test charts av...
