项目摘要

A novel image synthesis technology learning to the image information processing system of insect's compound eye has been studied. An individual lens of the insect's compound eye does not make the image of one per one, but synthesize s one image with a lot of micro lenses. We succeeded in the artificial achievement of this system. By adding the semiconductor electric conversion devices to this new image formation system, the achievement of a super-thin, micro video input device of l-mm or less in total thickness will become possible.The micro lens plate used in the experiment was manufactured with quartz and plastic in super-precision. Some angle difference was given to the superposed two lens plates. Disk-like Moire pattern is seen in shape to reflect the original periodic structure. When a certain gap was given to the two lens plates, this disk pattern works like an optical lens, and has a function of the image synthesis. Several thousand micro lenses are included in this disk pattern, and it is the same as the image synthesis technology of insect's compound eye.The followings are newly obtained.1. The lens plate gap necessary for synthesizing the image is not a fixed value of twice the focus distance of a micro lens, but depends on the distance between the object and the lens plates, and between the observer (camera) and the lens plates. We can apply this to the focus adjusting.2. The position of the image changes when the observer moves to the vertical direction from the optical axis. That is, the image moves downward when the camera moves to left. There is a possibility of applying to the reproduction of three dimensional information of the object.

针对昆虫复眼图像信息处理系统，研究了一种新的图像合成技术。昆虫复眼的单个透镜并不成像，而是用许多微透镜合成一个图像。我们成功地人工实现了这一系统。通过将半导体电转换器件添加到这种新的图像形成系统中，实现总厚度为1 mm或更小的超薄微型视频输入装置将成为可能。实验中使用的微型透镜板由石英和塑料超精密制造。叠加的两块透镜板之间存在一定的角度差。在形状上可以看到类似锯齿状的莫尔图案，以反映原始的周期性结构。当两个透镜板具有一定间隙时，该盘状图案像光学透镜一样工作，并且具有图像合成的功能。该圆盘图案包含数千个微透镜，与昆虫复眼的图像合成技术相同。合成图像所需的透镜板间隙不是微透镜的焦距的两倍的固定值，而是取决于物体和透镜板之间的距离以及观察者（照相机）和透镜板之间的距离。我们可以将其应用于焦点调整。当观察者从光轴向垂直方向移动时，图像的位置发生变化。也就是说，当相机向左移动时，图像向下移动。有可能应用于对象的三维信息的再现。
