We have been developing an extra-high quality electronic imaging system. The ultimate objective of this system is to reproduce or convey high-order sensations (HOS) invoked by original objects. Some of important HOS are the sense of elegance, refinement, dignity, and profundity. These senses are strongly more related to the reproduction of black and gradient than the reproduction of color.

The extra-high quality electronic imaging system is used in dark environment so that very low luminance of black (nearly zero) can be reproduced and observers can concentrate on the displayed images. In this situation, the reproduction of black and gradient is much more important factor than conventional.

In this paper, firstly the problem of conventional systems will be discussed. Secondly, how to treat the reproduction of black and gradient in the extra-high quality system will be described. Thirdly, practical experiments using a digital camera and the extra-high quality system will be done.

More about this publication?
  • Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
