Abstract
The present invention provides an image reading apparatus capable of reading images with a sufficiently wide dynamic range. An image reading apparatus of this invention has a light source, a reading section which generates image data based on light obtained from an original illuminated with light from the light source, a first level changing section which changes a light receiving level in the reading section in a first manner, a second level changing section which changes the light receiving level in a second manner different from the first manner, a control section in which plural light receiving levels are generated by synergistically changing a light receiving level, and a combining section which combines plural image data obtained by reading an image of an original at plural light receiving levels.
