    • 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。
