چکیده
The current CIE colour rendering index (CRI) has been widely used to test the quality of light sources over 30 years. However, this method is outdated and problematic, especially for evaluating white light emitting diode (LED) sources. A psychophysical experiment was conducted to evaluate the quality of three D65 simulators. The results were also compared with the CRI and the other method, known as CQS. Furthermore, both indices were modified based on CAM02-UCS, and some improvements were found.

The Concept of Colour Rendering Revisited
The currently used colour rendering index is based on an outdated colour space and chromatic adaptation formula. The perceived and calculated colour rendering of new light sources shows discrepancies. This becomes acute with the introduction of LED sources and increased use of coloured samples produced by ink-jet printers and colour-photocopy. Recent colour appearance models enable an advanced ...
متن کاملLED-based metameric light sources: Rendering the colours of objects and other colour quality criteria
Solid-state white light sources based on multiple light emitting diodes (LEDs) have three features that make them radically different from other sources of electrically generated light. These are the narrowband spectra of the individual LEDs, the possibility of controlling the light output of the individual LEDs and the limited stability of the LED’s colour. These features make it possible to a...
متن کاملColour Appearance Modelling for Self-luminous Colours
An experimental setup and procedure for the evaluation of selfluminous colours viewed against both dark and luminous backgrounds is presented. Physical and visual data of self-luminous colours is gathered in order to develop a Colour Appearance Model for self-luminous colours under different viewing conditions. This model is needed for the evaluation of light sources.
متن کاملColour Appearance Descriptors for Image Browsing and Retrieval
In this paper, we focus on the development of whole-scene colour appearance descriptors for classification to be used in browsing applications. The descriptors can classify a whole-scene image into various categories of semantically-based colour appearance. Colour appearance is an important feature and has been extensively used in image-analysis, retrieval and classification. By using pre-exist...
متن کاملA Comparison between CIECAM97s and its Revised Colour Appearance Models for Apearance Attributes of Fabrics
: The CIECAM97s and its revision, as a colour appearance model, were applied for a series of fabrics with different colours and depths to explain their colour appearance coordinates in similar viewing conditions. The results show that due to some modifications which expand the scale, the modified model has improved capadilities in calculating chroma. Besides, the calculations were simpler for t...
