パネルディスカッション 第１部：パワーユーザーと色処理専門家の連携で拓く新世界 分光情報を用いる色彩画像処理とその応用 三宅 洋一 千葉大学工学部情報画像工学科 The 1st Symposium of the 'Color' of Digital Imaging in Medicine Panel Discussion Part 1 : Cooperation of Power Users in Medicine and Specialists of Color Technologies for Pioneering a New Frontier Development of a Multispectral Imaging System and its Possible Applications Yoichi MIYAKE Department of Information and Image Sciences, Chiba University Overview Because conventional photographic films and CCDs record colorimetric values of only three primary colors, red, green and blue (RGB), they do not meet the requirements of such fields as art and medicine, in which extremely precise reproduction of colors is critical. Simultaneously, various media used for digital imaging have developed independently and the data compatibility among them, especially the stable reproduction of colors, is now being recognized again, with such concept as 'Device Independent Color Reproduction' (DICR), 'Color Management' and 'Color Portability' being introduced. To these problems, multispectral imaging, which makes it possible to record the spectral reflectance of objects for accurate color reproduction, will give an important solution. Fig. 1 shows a model of color reproduction of the object which has the spectral reflectance O(x, y, lambda) illuminated by the light source which has the spectral radiant distribution E(lambda), and clarifies that the measurement of spectral reflectance settles the basis to design the accurate reproduction of colors in this model. In this presentation, various latest researches based on the model are introduced. |
