    Pine wilt disease is spreading out in Japanese pine forest. Control efforts have been taken on the infested trees which become the source of infection in the next year. Infested trees are scattered around large forest areas, which makes it difficult to identify and treat them. We developed a special technique of 3D-measurement using aerial photography. The positions of the infested trees are identified and measured from a stereo pair of aerial photographs, ground navigation system in the forest, and the automatic flight system of the unmanned helicopter. The total system to control pint wilt disease can be effective to the other forest diseases.

    Auditory modality contributes significantly to the perceptual and emotional reality of events in the external world. The mapping between the physical properties of sounds and auditory percepts is not straightforward. The discrepancies, or illusions, are not mere errors in processing. Rather, they reflect adaptive information processing strategies for the brain to interpret what is occurring where in the external world (i.e., auditory scene analysis) efficiently and appropriately, and thus an essential element of the reality. Another element of the reality is physiological responses of the autonomic nervous system and the endocrine system in response to emotional values of sounds, such as pleasantness or unpleasantness. The emotional responses to sounds represent adaptive functions for the brain to adjust body states in accordance with current situations. The emotional responses provide useful ways to evaluate the reality of sounds objectively.

  • «Invited Lecture»Video parameters of Super Hi-Vision and their psychophysical effects
    Yukihiro NISHIDA
    Session ID: 11-03-03
    Published: November 10, 2011

    NHK has invested considerable effort in researching and developing an extremely high resolution video system called Super Hi-Vision that can provide an increased sense of presence as well as the sense of realness to viewers. It has been designed with the optimum video parameters for two-dimensional motion images on the basis of the psychophysical characteristics of human vision. This paper describes the video parameter values of Super Hi-Vision, including spatial and temporal resolutions and tone and colour reproduction, and the importance of Super Hi-Vision as a future television system.

    The ability of embodied interaction is the important aspect of high presence telecommunication systems. However, anisotropism of the communication media is one of the serious problems of such systems. In order to alleviate this problem, a system should capture the bodily actions involuntarily conducted by a user and properly reproduce the actions at the remote site. In order to challenge this issue, the authors have been studying a telecommunication systems that use robots as communication media. This paper introduces three examples of such studies.

  • «Invited Lecture»10 Years of 4K Image Technologies
    -Recent Developments in Ultra Realistic Image Systems-
    Kunio YAMADA
    Session ID: 11-03-05
    Published: November 10, 2011

    Ten years have passed since JVC's development of the 4K projector in 2001. Since then, ultra high resolution image technologies, with 4K or more resolution, have made great progress and have been widely spread. Projectors have been improved. 4K cameras have been developed. Furthermore, the 4K technologies have been applied for glass-less 3D displays. This paper denotes 10 years of progress of the 4K technologies and their recent achievements.

    We discussed the importance of enhancing the sensation of reality, that is, the feeling that the observer is holding one or more real objects in his or her hand. Some approaches, which strengthen the sensation of reality, are introduced: such as a high quality multi-view 3D display, a multi-view image interpolation technique, a head tracking system to expand the viewing and a force feedback type 3D display.
