Color Correction Problem of Image Displayed on Non-white Projection Screen
نویسندگان
چکیده
The use of projectors in various applications and environments has raised the need to adapt the displayed image to the viewing display environment. The displayed image under bright light may appear with washed colors and attenuated contrast. Similarly, the appearance of the displayed image may be affected by the reflectance and the geometry of the projection screen. Based on the model of the perceived image formation, we formulate the problem of the color correction using the constancy between the perceived image and its original one. We verify through formal and empirical validations that the proposed method significantly preserves the image’s color.

Real time computer graphics are limited in that they can only be displayed on projection screens and monitors. Monitors and projection screens cannot be used in live fire training or scenarios in which the displays could be physically damaged by trainees. To address this issue, we have developed projection systems using computer vision based color correction and image processing to project onto...

Recently, projector is one of the most common display devices not only for presentation at offices and classes, but for entertainment at home and theater. The use of mobile projector expands applications to meeting at fields and presentation on any spots. Accordingly, the projection is not always guaranteed on white screen, causing some color distortion. Several algorithms have been suggested t...
متن کاملColor constancy for visual compensation of projector displayed image
The color of a displayed image by a projector can be distorted by features of the device, the ambient light, the projection screen, and also the observer. This has raised the need to correct the image during the display to eliminate these effects and to ensure a constancy of the color appearances. In this paper, we propose models for controlling the appearance of the displayed image. We argue t...
متن کاملSequential color breakup measured with induced saccades
The commercial success of color sequential displays is limited by the fact that people perceive multiple color images during pursuit and saccadic eye movements. We conducted a psychophysical experiment to quantify visibility of these color artifacts for different saccadic speeds, display background brightness, and target size. An Infocus sequentialcolor projector was placed behind a projection ...
