Author Biography:
Dr. János Schanda is professor at the University Veszprém and Head of the Department of Image Processing and Neurocomputing. His main interest is in colorimetry of visual display units (VDUs), colour rendering and colour appearance. He was for more then 10 years the Technical Director of the CIE (International Commission on Illumination). He published many papers on colorimetry, the metrology of LEDs and VDUs. He is the author of the chapter of colorimetry in the recently published book on Applied Photometry published by the Optical Society of America. He is at present chairman of several fundamental technical committees of the CIE, such as the committees re-writing the basic publications on colorimetry and colour rendering and is raporteur for improved colorimetry.
