Image inputting apparatus |
摘要 |
In an optical system, when a binary image is to be read, a first reducing projection lens is located onto an optical axis and focuses an image of the original at a first magnification (relatively high magnification), and a mirror divides the entire image into three divided images which will be then projected onto three CCDs, respectively. On the other hand, when a multivalued image is to be read, a second reducing projection lens is located onto the optical axis and focuses an image of the original at a second magnification (relatively low magnification) which is lower than the first magnification, and the entire image is projected onto one of the three CCDs.
