  • Patent number: 9007667
    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.

  • Patent number: 8988743
    Abstract: According to one embodiment, a document detecting apparatus includes a light-emitting element, a photoelectric conversion element, a light-emission controller and a detection processor. The light-emitting element projects light onto a detection position of a document. The light-emitting element is not used for reading an image of the document. The photoelectric conversion element converts light projected onto the detection position into an electric signal and outputs the electric signal. The light-emission controller changes the light quantity of the light emitted by the light-emitting element during a predetermined interval. The detection processor detects the presence or absence of the document at the detection position of the document based on whether a value of the output electric signal during the predetermined interval changes in correspondence to the change of the light quantity caused by the light-emission controller.
