Department of Image Sciences






‘Image Science’ ? It is a very important research field for realizing our ideal future through images.

Since we receive many parts of information through eyes, imaging has been playing an important role for communication tools. In addition, imaging technology has been developing from a photograph and a printing such as a recording and/or a large quantity reproduction technology for a long time. These technologies are very important and are applied widely in a current information-oriented society, even if it is an invisible part inside an electric circuit board.

Generally, recording, storage, transmission, and displaying are fundamental components of image systems. Light sources and image processing are also essential. Image recording is equivalent to two-dimensional light detection, which may be provided by photochemical reactions or photoelectric conversions. Recording is related to alterations of many kinds of physical and chemical properties of substances by detected signals or by light energy itself. Optical fiber system is an important one for high-speed transfer of image information. Displaying is concerned with reconstruction of image with light and color regulations, using dyes, pigments, toners, fluorescence, LED, laser light, liquid crystals, etc. Although recent progress of digital technology has created a revolution in the field of image science, the elements of image system are common in both analog and digital ones. At the same time, continuous development of new materials and devices with originalities is required toward the future of image science and technology.

These image technologies are supported by fundamental sciences such as chemistry, physics, mechanics, electronics, and optics, and by frontiers of engineering. We have important academic experiences concerning with innovation and application technology on imaging materials as well as imaging processing technology as the only one state university in Japan. Image Science makes every endeavor to serve as a leading source of scientific research in imaging field. Our department, Department of Image Science, aims to promote joint research among the image science and other high technologies and to produce sophisticated scientists and researchers who have comprehensive perspective and can challenge scientific, industrial, economic, and social problems.

The Department of Image Science has three subjacent research fields, Image Chemistry, Image Applied Physics, and Image Displaying. The fields closely cooperate to improve image science and technology effectively. In the Image Chemistry field, chemical procedures are applied to create new devices and materials for image science and technology. It gives the examples in this field, which are light recording materials such as photosensitive organic ones, photo-lithography, preparation and application of functional materials in the forms of thin films, mono-disperse particles, nano-particles and nano-wires, electric papers, and display devices including organic EL, organic field emission, and electrochromic one, and so on. The Image Applied Physics field focuses physical and chemical interactions between substances and light or other radiations to create and improve technical elements in image science and technologies on the basis of both fundamental and applied researches. The division is dealing laser physics and technologies, photo-electronic imaging devices, optical fiber systems, holograms for 3D recording, detection of radiations including heavy particle lays and sensor devices for instance. To show real and beautiful images, the Image Displaying field investigates novel image systems and their ingredients, such as full-color hard copy systems, rewritable papers, and paper-like displays. In addition, human sensitivities are attempted to involve in image analysis and evaluation procedures to realize image expressions comfortable for us.
