    • When a scanning start position set signal is input in an area image sensor, the content is transferred to a vertical scanning circuit, and the scan start position is set. Image of a desired row is read by horizontal scanning. Then, one shift signal for vertical scanning is input, the position of scanning is shifted by one row, and horizontal scanning is performed. Thus image of the next row is read. By repeating this operation, a desired strip-shaped image is read. The shape of the object is determined and when a portion is determined to have complicated shape, the image data is input by means of a lens having long focal length, and image data of other portions are input by means of a lens having short focal length. By putting together a plurality of input image data, image data as a whole is generated.
    • 当在区域图像传感器中输入扫描开始位置设置信号时,将内容传送到垂直扫描电路,并设置扫描开始位置。 通过水平扫描读取所需行的图像。 然后,输入用于垂直扫描的一个移位信号,扫描的位置移位一行,并进行水平扫描。 因此,读取下一行的图像。 通过重复该操作,读取期望的条形图像。 确定物体的形状,并且当确定部分具有复杂形状时,通过具有长焦距的透镜输入图像数据,并且借助于具有短焦距的透镜输入其他部分的图像数据 。 通过合成多个输入图像数据,生成整体的图像数据。

    • On one side of a liquid crystal layer, a first electrode is provided, and, on the other side of the liquid crystal layer, a second electrode, composed of a plurality of individual electrodes, and a third electrode are provided. The second and third electrodes have holes that are increasingly small away from the liquid crystal layer. When the potential at the third electrode is set equal to or lower than the potential at the second electrode, the liquid crystal layer acts as a convex lens; when the potential at the third electrode is set higher than the potential at the second electrode, the liquid crystal layer acts as a concave lens. The range in which the focal length can be varied depends on the diameters of the holes, and giving the holes of the different electrodes varying diameters helps widen the range. Moreover, conductors can be laid to reach the electrodes at the outer edges thereof so as not to directly face the liquid crystal layer. This helps eliminate the influence of the conductors on the electric field distribution in the liquid crystal layer.
    • 在液晶层的一侧,设置第一电极,并且在液晶层的另一侧设置有由多个单独电极构成的第二电极和第三电极。 第二和第三电极具有远离液晶层的孔越来越小。 当第三电极处的电位设定为等于或低于第二电极处的电位时,液晶层用作凸透镜; 当第三电极处的电位被设定为高于第二电极处的电位时,液晶层用作凹透镜。 焦距可以变化的范围取决于孔的直径,并且给不同电极的孔改变直径有助于扩大范围。 此外,可以铺设导体以在其外边缘处到达电极,以便不直接面对液晶层。 这有助于消除导体对液晶层中电场分布的影响。
