چکیده

The primary goal of a colour characterization model is to establish a mapping from digital input values di (i=R,G,B) to tristimulus values such as XYZ. A good characterization model should be fast, use a small amount of data, and allow for backward mapping from tristimulus to di. This paper demonstrates implementations of three different colour characterization models, each tested on seven display devices. The characterization models implemented in this study are a 3D LUT, a linear model [2], and the masking model introduced by Tamura et al. in 2002 [6]. The devices include two CRT Monitors, three LCD Monitors, and two LCD Projectors. Several characteristics of the display devices are presented in relation to data collection and characterization modeling. These include the long phosphor stabilization time on CRT monitors and the shifting chromaticity of mixed colours on LCD displays. The results of this study indicate that a simple linear model is the most effective for all devices used in the study, despite the common belief that it is sometimes inappropriate for LCD monitors. A simple extension to the linear model is presented, and it is demonstrated that this extension improves white prediction without causing significant errors for other colours.

Introduction & Objective: The use of computers and monitors (displays) has been developed due to their increasing capabilities. The presence of electromagnetic fields, infrared and ul-traviolet radiations has been proven around the display, which all of them have adverse ef-fects on human health. Therefore, this study was conducted to survey and compare the mentioned variables around the disp...

Tone Mapping Operators on Small Screen Devices: An Evaluation Study

In the last decade, an increasing number of techniques have been developed to reproduce high dynamic range imagery on traditional displays. These techniques, known as Tone Mapping Operators (TMOs), have been compared and ranked in different ways according to several image characteristics. However, none of these algorithms has been developed specifically for small screen devices (SSD). In this p...

Optimal Linear RGB-to-XYZ Mapping for Color Display Calibration

Color display calibration, in part, involves mapping input RGB values to corresponding output values in a standardized color space such as CIE XYZ. A linear model for RGB-to-XYZ mapping is based on a 3-by-3 linear transformation matrix T mapping data from (linearized) RGB to XYZ. Such a mapping is often determined by least squares regression on the difference between predicted and measured XYZ ...
