Abstract
According to one embodiment, an image reading apparatus includes an exposure unit, a light sensor, and a controller. The exposure unit selectively emits light to positions along a first scan direction to write pixels in accordance with a main scan line of image data. The light sensor is at a position to receive light from the exposure unit and is configured to output a synchronization signal according to the detection of the light emitted for each main scan line of image data. The controller adjusts a starting pixel position along the first scan direction for a main scan line of image data based on a change in an output interval of the synchronization signal resulting from a change in an intensity of light emitted by the exposure unit.
