Abstract:
1. An image reader for reading an original image formed on a surface of a recording medium comprising: an illumination unit configured to illuminate the surface with a white light source, a light receiving unit comprising color image sensors each configured to receive light reflected from the surface to form a monochromatic image; an image processing synthesis unit configured to process monochromatic images from the light receiving unit to form a synthesized image; an operation unit configured to designate a specific color; and a control unit configured to control the image processing synthesis unit to exclude, from the synthesized image processing, the monochromatic image from a respective one of the color image sensors that corresponds to the specific color designated in the operation unit; wherein the color image sensors comprise a red image sensor, a green image sensor, and a blue image sensor; and wherein the image processing synthesis unit is further configured to process the monochromatic images received from the light receiving unit with a binary-coded processing.
