This document describes a method for analysing imaging systems quality in the area of cultural heritage imaging. The method described analyses multiple imaging systems quality characteristics from a single image of a specified test target. The specification states which characteristics are measured, how they are measured, and how the results of the analysis need to be presented. This specification applies to scanners and digital cameras used for digitization of cultural heritage material. NOTEÂ Â Â Â Â Â This document addresses imaging of reflective originals, a future part two will address imaging of transparent originals.

ISO/TR 19263-1:2017 specifies how to perform quality analysis of imaging systems (e.g. flatbed scanners, planetary scanners, or digital still cameras) used for digitization of reflective two-dimensional originals. Original materials include but are not limited to books, textual documents, drawings, prints, photographs, and paintings. Certain types of two-dimensional materials with complex surface geometry and or highly reflective surface elements require special illumination techniques that can fall outside the scope of this document. NOTE ISO/TS 19264‑2 will address transmissive materials.

⎯appraisal of the tone reproduction and colourfulness of prints and transparencies at illumination levels similar to those for practical use, including routine inspection;
⎯critical appraisal of transparencies that are viewed by projection, for comparison with prints, objects or other reproductions; and
⎯appraisal of images on colour monitors that are not viewed in comparison to any form of hardcopy.
This International Standard is not applicable to unprinted papers.

This part of ISO 5 specifies the geometric conditions for measuring ISO 5 standard diffuse and f/4,5 and f/1,6 projection transmittance densities. ISO 5 standard diffuse density is primarily applicable to measurements of photographic images to be viewed on a transparency illuminator, or viewing box, to be contact printed, or to be projected with a system employing diffuse illumination. ISO 5 standard projection density is primarily applicable to measurements of photographic images to be projected with systems employing optical condensers. Although primarily intended for the measurement of photographic images, the densitometric methods specified in this part of ISO 5 are often applied to optical filters and other transparent materials.

IEC 61966-9:2003 defines methods of measurement designed to make possible the objective performance assessment and characterization of the colour reproduction of digital cameras which can capture colour still and moving images, and output colour information corresponding to red - green - blue digital image data. The measured results are intended to be used for the purpose of colour management in multimedia systems, typically in the Internet. This bilingual version (2013-03) corresponds to the monolingual English version, published in 2003-11. This second edition cancels and replaces the first edition published in 2000. It includes the following significant technical changes:
- In the light of issuing IEC 61966-2-2, the relevant reference IEC 61966-2-1 in Annex C has been replaced by IEC 61966-2-2 together with sRGB by scRGB.
- The previous Annex C has been replaced by the new Annex C where the previous Figure C.1 has been deleted.
