Color Rendering Properties of LED Light Sources
A laboratory human factors experiment was conducted to understand the color rendering properties of various LED-based reading lights. Human subjects rated their preference for a given scene illuminated by a test light source compared to an identical scene illuminated by a reference light source. In another experiment the same subjects viewed and rated the scenes individually when illuminated by...
متن کاملImproving Edge Based Color Constancy for Multiple Light Sources
Color constancy algorithms are used for making illuminant independent images. Illuminant independency is achieved in most of algorithms by uniform light source assumption. But this condition may violate in most of real world images which introduces performance failure in computer vision applications like object tracking and object recognition. Local color correction for up to two light sources ...
متن کاملColor Correction for Tone Reproduction
High dynamic range images require tone reproduction to match the range of values to the capabilities of the display. For computational reasons as well as absence of fully calibrated imagery, rudimentary color reproduction is often added as a postprocessing step rather than integrated into the tone reproduction algorithm. However, in the general case this currently requires manual parameter tuni...
متن کاملSix-primary color projection display for expanded color gamut reproduction
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...
متن کاملBase models for color halftone reproduction
One of the main challenges for the characterization of printing systems consists, for a given substrate, in establishing the relationship between surface coverages of the selected set of inks and the spectral reflectances of the printed ink halftones. Knowledge of print halftone spectral reflectances enables deducing their colors. Models enabling the prediction of spectral reflectances as a fun...
