Abstract:
1. An image reading apparatus comprising: an illuminator adapted to illuminate an original, said illuminator including a plurality of white light emitting elements, and a plurality of colored light emitting elements adapted to emit lights of different colors and arranged in a manner associated with each of said respective white light emitting elements; a controller adapted to cause said colored light emitting elements to emit lights, so as to correct a color of light emitted from each of said white light emitting elements; and a reader adapted to read the original illuminated by said illuminator, wherein a particular one of said white light emitting elements is a white LED, wherein said controller is adapted to cause one or more of said colored light emitting elements that are more adjacent to said white LED than the others of said colored light emitting elements to emit light having a red component and a green component in response to said white LED emitting bluish white light, wherein said controller is adapted to cause one or more of said colored light emitting elements that are more adjacent to said white LED than the others of said colored light emitting elements to emit light having a blue component in response to said white LED emitting yellowish white light, wherein said plurality of white light emitting elements are arranged linearly in an array, wherein said plurality of colored light emitting elements are arranged linearly in an array parallel to and adjacent the linear array of white light emitting elements in a manner that each of a plurality of groups of colored light emitting elements is aligned with one white light emitting element, and wherein each of the groups of colored light emitting elements includes a sequence of different-colored light emitting elements.
