摘要： PROBLEM TO BE SOLVED: To provide a color imaging/color display device for imaging reflected light of illuminating light and displaying its image at real time in color on a display of the display device, at a low cost by further simplifying configuration.
SOLUTION: This device uses an illuminating light source 12 for switching the light of fundamental colors in predetermined order to project the light, as an illuminating means, uses a solid imaging element 2 for black and white as an imaging means, and uses a backlight-type black-white liquid crystal display element 24 capable of changing the color of light of the backlight 24 to the same fundamental color synchronously with the color change of light of the light source, as the display of the display device 20. When the illuminating light source 12 emits light of a certain fundamental color, the color of the backlight 24 when an image signal by the solid imaging element 2 of an observation image (a photographed object image) by the light is displayed by the liquid crystal display element 22, turns into the fundamental color emitted from the light source.

摘要： PROBLEM TO BE SOLVED: To enable appropriate diffusion in two directions different from each other and project a bright projection image with less unevenness by using a relatively simple structure.SOLUTION: An anisotropic light diffusion layer 4 has a property of diffusing projection light PL and reflection light RL in an X direction, and an optical control layer 3 has a property of diffusing the reflection light RL in a Y direction. In this case, diffusion by the anisotropic light diffusion layer 4 is in a wider range. Thus, a view angle can be widened in the X direction, in particular in the longitudinal direction for an observer EY, in a properly diffused state by using a relatively simple structure. Moreover, because a light reflection layer 2 has light reflection parts PP on a plurality of prism parts 2a having a saw teeth shape in cross-section, a proper diffusion state can be secured and a bright projection image with uneven brightness or illuminance suppressed can be projected by folding back the projection light PL as the reflection light RL having a desired angle surely diffusing it.
摘要翻译：要解决的问题：为了使得能够在彼此不同的两个方向上进行适当的扩散，并且通过使用相对简单的结构投射具有较小不均匀性的明亮的投影图像。解决方案：各向异性光扩散层4具有在X方向上扩散投射光PL和反射光RL的性质，并且光学控制层3具有使反射光RL在Y方向上扩散的性质。在这种情况下，各向异性光扩散层4的扩散在更宽的范围内。因此，通过使用相对简单的结构，能够以适当的扩散状态在X方向，特别是纵观方向上对视角加宽。此外，因为光反射层2在具有锯齿形状的多个棱镜部分2a上具有光反射部分PP，所以可以确保适当的扩散状态，并且可以抑制亮度或照度不均的亮投影图像通过将投影光PL折回作为具有期望角度的反射光RL来确定地扩散它来投射。版权所有（C）2012，JPO＆INPIT
