ジャーナル フリーColor appearance of object colors in a complex visual field is studied by a nonlinear color-appearance model of Nayatani et al. The experimental results by McCann et al. using a Color Mondrian are analyzed by the model. The analyses clarified that the experimental results are estimated well by introducing an incomplete adaptation mechanism to the nonlinear color-appearance model.抄録全体を表示PDF形式でダウンロード (929K) -

ジャーナル フリーAn experiment was conducted on the degradation of visibility when affected by glare light sources near the visual line, to examine the effects of glare light source size and eccentricity, and background luminance on the equivalent veiling luminance. In this experiment, a circular glare light source of diameter 3 to 27 minutes was presented near the visual line of an observer. Landolt rings were employed as test objects on a screen panel. When the size of the glare light source was relatively small, the rate of degradation in visibility depended on not only the luminous intensity of the light but also its size.抄録全体を表示PDF形式でダウンロード (417K) -

ジャーナル フリーComfortableness in various spaces is recently gaining priority. For comfortable lighting in a desk work area, visual comfort in the environment as well as good visual performance are required during a long desk work with visual tasks such as reading and writing documents. Preferable illuminance and luminance on surrounding surfaces in relation to the task (on the desk) illuminance should be determined appropriately. Since general lighting is usually used as office lighting, the previous paper clarified the preferred wall illuminance and luminance in relation to desk illuminance. On the other hand, task-ambient lighting has been proposed to save energy. In this paper, the following items are clarified with respect to the task-ambient lighting.
(1) Preferred ambient illuminance in relation to task illuminance
(2)Preferred wall illuminance in relation to task illuminance
Further, with the use of task-ambient lighting based on the results above, even with energy-saving ambient illuminance, the ratio of consumed wattage per worker between general lighting and task-ambient lighting, is obtained through a simple calculation; the result reveald that the power saving amount to as much as 40-55%.抄録全体を表示PDF形式でダウンロード (1140K)
