Bibliography

IEC 61966-8:2001 is applicable to the characterization and assessment of multimedia colour scanners used in computer systems, multimedia and similar applications. It is drafted to make possible the characterization and objective performance assessment of multimedia colour scanners which can capture colour images and output colour information such as red, green and blue data from reflective originals. The measured results are intended to be used for the purpose of colour management in multimedia systems. Measurement conditions, possible methods of measurement and characterization are defined to make colour management possible.
