Image reading apparatus for reading an image containing both a negative area and a positive area |
摘要 |
The image reading apparatus of this invention reads a desired image out of an original document with a CCD 1, edits a desired area of the thus read image with an edit processing part 4, and causes the edited area to be copied without being subjected to negative-positive inversion. The edit processing part 4 sets an optimum density severally for an area requiring negative-positive inversion and for an area not requiring negative-positive inversion. Thus, necessary information existing in the area of image and the area outside the image can be printed out without causing the formation of a completely black frame and density of the print can be optimized without discrimination between these areas.
