Evaluation of Device Color Gamut Description Algorithms
Applied Mechanics and Materials, 2015A well performed gamut boundary description (GBD) algorithm is the foundation of color gamut mapping and it is also a guarantee for color management to acquire a good results. In order to get a more accurate color gamut boundary and have a intuitive view of what can be reproduced by the device, several GBDs have been presented in the past, since there ...

Research on Gamut Visualization Method of the Color Output Device
Journal of Display Technology, 2016Different color output devices generally possess different color gamut. The visual description of color gamut on an output device is very significant for understanding the performance of the equipment and predicting color image output effect. Based on the layer cutting method on the lightness axes’ chromaticity coordinate, this paper provides a new way

Matrixing, number of color channels, and color gamut of camera devices
SPIE Proceedings, 2007In this paper we investigate the relationship between matrixing methods, the number of filters adopted and the size of the color gamut of a digital camera. The color gamut is estimated using a method based on the inversion of the processing pipeline of the imaging device.

Color gamut boundary optimization of wide gamut display devices
SPIE Proceedings, 2011High-end monitors based on LCD technology increasingly address wide color gamut implementations featuring precise color calibration within a variety of different color spaces such as extended sRGB or AdobeRGB. Combining a Look- Up-Table method with linear interpolation in RGB component space using 3x3 matrix multiplication provides optimized means ...

A new device color gamut boundary description algorithm based on irregular segmentation
Color Research & Application, 2016AbstractThe description of device color gamut is very important for color gamut mapping, which plays an important role in cross‐media color reproduction. To get a more accurate color gamut boundary, several gamut boundary description (GBD) methods have been presented in the past; however, many problems still exist in the current algorithm (e.g ...

Wide gamut device-independent colour image interchange
International Broadcasting Convention - IBC '94, 1994The article discusses some aspects of colour reproduction in CRT cameras and displays, photography and offset printing. It explains how colour data can be coded in calibrated, nonlinear RGB values in order to take advantage of accurate colour interchange, and how colours outside the gamut of RGB primaries can be conveyed using an extension of RGB ...

29.6: Research on Gamut Expansion Mapping Method Based on Laser Display Device
SID Symposium Digest of Technical Papers, 2019Because the trichromatic coordinates of the laser display devices used in the wide gamut and are greatly different from the exiting television (TV) signals. Therefore when the TV signals is input to drive the laser display device, color distortion and color deviation may occur to influence the subjective experience.

Organic light emitting diodes (OLEDs) are considered to be among the best flat panel display technologies owing to their wide viewing angles, high-speed response, high resolution, and simple structure. OLEDs exhibit a wide color gamut exceeding 100 % of the national television system committee (NTSC) sRGB gamut ratio.

Mapping the Broad CMY Subtractive Primary Color Gamut Using a Dual-Active Electrochromic Device
ACS Applied Materials & Interfaces, 2014Although synthetic efforts have been fruitful in coarse color control, variations to an electrochromic polymer (ECP) backbone are less likely to allow for the fine control necessary to access the variations and shades of color needed in display applications. Through the use of thin films of cyan, magenta, and yellow ECPs, non-emissive subtractive color
