Claim Text:
1. An image reading apparatus comprising: an illumination unit that is disposed so as to be moved relative to a recording medium and illuminates the recording medium with light beams of plural colors that are circulated in predetermined order; a reading unit that reads an image recorded on the recording medium by receiving reflection light that is produced as a result of the illumination unit's illuminating the recording medium during the moving relative to the recording medium; and at least one central processing unit configured to function as a control unit that controls the illumination unit so that a difference between a first illumination interval between adjoining colors within each illumination cycle of light beams of the plural colors circulated in the predetermined order and a second illumination interval from illumination with light of a last color of the cycle to illumination with light of a first color of a next cycle is determined based on a reading resolution of the reading unit.
