Abstract
According to an embodiment, an image reader for reading an original image formed on a surface of a recording medium is disclosed. The image reader comprises an illumination unit configured to illuminate the surface with a white light source, a light receiving unit comprising a plurality of color image sensors each configured to receive light reflected from the surface to form a monochromatic image, and an image processing synthesis unit configured to process the monochromatic images from the light receiving unit to form a synthesized image. The image reader further comprises 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 the color image sensor that corresponds to the specific color designated in the operation unit.
