ABSTRACT:
There is described an image reading apparatus that reads image information from a document, such as a negative film, a photographic prints, etc., on which image information is recorded. The image-apparatus includes a plurality of light sources for emitting lights, wavelengths of which are different relative to each other; an image-reading section to read the image by detecting either transmitted lights or reflected lights, which are obtained by irradiating the lights emitted from the plurality of light sources onto the image recorded on a document; and a light-amount adjusting section to independently adjust each amount of the lights emitted by the plurality of light sources, when the image-reading section reads the image.
