Effect of ambient light sourcea on the appearance of color image on CRT monitor

چکیده
Color images are usually viewed on CRT monitor screen under ambient light sources. The feeling for reproduced color on CRT monitor depends on white point of ambient light source and the CRT monitor screen'-3. Therefore, if the effect of ambient light source is not considered, then the reproduced color does not match the intrinsic color. This paper proposes a method to investigate the effect of ambient light source on color appearance of a CRT monitor which is positioned in a room illuminated by an experimental light source. The investigation for the effect of ambient light consists of two elements. One is the flare effect that the reflection on the CRT monitor screen which produced by the ambient light source. Another is the change of adaptation in white point. When the images are viewed on a CRT monitor screen under ambient light, the state of adaptation is affected by both the white point of the monitor and ambient light source. Therefore, these two effects were analyzed in the experiments.

Practical method for appearance match between soft copy and hard copy
CRT monitors are often used as a soft proofing device for the hard copy image output. However, what the user sees on the monitor does not match its output, even if the monitor and the output device are calibrated with CIE/XYZ or CIE/ L*a*b*. This is especially obvious when correlated color temperature (CCT) of CRT monitor’s white point significantly differs from ambient light. In a typical offi...
متن کاملAppearance Match between Soft Copy and Hard Copy under Mixed Chromatic Adaptation
Human visual system is partially adapted to the CRT monitor’s white point and partially to the ambient light, when comparing a soft-copy image with the reproduced hard-copy image. The visual experiments were performed on the effect of the ambient lighting under mixed chromatic adaptation. It was found that human visual system is 40% to 60% adapted to CRT monitor’s white point and the rest to th...

We investigated the eeects of ambient illumination on the color appearance of CRT which was positioned in a room illuminated by experimental illuminants, F2, F5, and F8. The luminance of these illuminants were controlled at three levels. The observers adjusted a color patch on the CRT to nd achromatic matching on a random color background. The chromaticity of the achromatic color was shifted to...

Texture and color appearance of froth is a discreet qualitative tool for evaluating the performance of flotation process. The structure of a froth developed on the flotation cell has a significant effect on the grade and recovery of copper concentrate. In this work, image analysis and neural networks have been implemented to model and control the performance of such a system. The result reveals...
متن کاملVisual Scaling of Image Quality for CRT displays
Two computer-controlled monitors with different peak luminances and faceplate reflectances, but with identical calculated contrast, were evaluated visually to determine which had higher perceived contrast and which was preferred. The results of the visual experiment indicated that photometric-based contrast measurements did not predict perceived contrast whereas monitor peak luminance was more ...
