Abstract: In a shadow process mode, a scanner reads out an original with a first exposure lamp in a first scanning operation. The readout image data is stored in an image memory via an I/O control unit. In the second scanning operation, the scanner reads out the original with a second exposure lamp having an illumination direction different from that of the first exposure lamp. The image data read out in the second scanning operation and the data stored in the image memory are subtracted for each pixel by a subtractor. The difference thereof is compared with a predetermined value in a comparator. The compared result is output to a selector, whereby a desired image data is provided to a printer processing unit via the I/O control unit.

Abstract: In reading out an original image divided into a plurality of regions, a scanner reads out image data having each divided region partially repeated for each adjacent divided region. The read out image data of each divided region is stored in a memory in correspondence with the original image and stored in a memory. A controller identifies an overlapping region of the stored image data, and joins each image data according to the identified result to generate an image data corresponding to the original image.
