Description

This Technical Report is concerned with the evaluation of colour differences between two similar images where the output media and the output viewing conditions are similar for both images. It is based on previously published work by CIE and other experts in this field. The report begins by reviewing the factors affecting the evaluation of these colour differences. Various methodologies are described to evaluate colour differences using both visual and instrumental methods. A series of reference colour digital images are presented. A method for statistically analysing average colour differences is described. All the activities of the Technical Committee in charge of this report are finally summarized and recommendations are made to apply either CIELAB or CIEDE2000 for evaluating colour differences for a pair of images displayed in the same medium side by side under the same illumination conditions.

The publication is written in English, with a short summary in French and German. It consists of 50 pages with 22 figures and 7 tables.

Description

This new edition of the International Lighting Vocabulary (ILV) is the result of intensive work carried out by the Divisions of the CIE to update, and supplement where necessary, the contents of the previous edition (1987). Many new terms have been added, to reflect changes in technologies and practices, existing terms have been updated as necessary, and obsolete terms have been removed.

The aim of this edition of the International Lighting Vocabulary is to promote international standardization in the use of quantities, units, symbols and terminology related to the science and art of light and lighting, colour and vision, photobiology and image technology.

This vocabulary provides the definitions and essential information necessary for the understanding and correct usage of the terms included. It does not give extensive detail or explanations of the application of these terms; such information, relevant for experts in each specialized field, is available in the Technical Reports and Standards produced by the CIE.

For this new edition it was decided to restructure the vocabulary to a fully alphabetical arrangement (based on the English terms), without any division into sections or sub-sections. This decision was taken in order to simplify the ILV and aid its use.

The Standard comprises 203 pages and presents the definitions of 1448 terms related to light and lighting.
