Abstract
An image reading apparatus includes: a plurality of light sources to emit light to a target to be read from a plurality of different irradiation positions; an illumination controller to sequentially and alternately turn on or off the plurality of light sources with a blinking cycle not perceptible to the human eye; an image capturing device to photoelectrically convert, pixel by pixel, reflected light of the light emitted to the target from the plurality of light sources to capture a plurality of read images; a memory to store one or more read images of the plurality of read images being captured; and a synthesizer to synthesize preset regions of the plurality of read images using the one or more read images stored in the memory to generate a synthesized read image representing the target, the preset region of each of the plurality of read images having an image level change caused by reflected light that is smaller than a threshold.
