PROBLEM TO BE SOLVED: To provide an image reading apparatus capable of suppressing the deterioration of the color balance of an output image without causing device complication and largeness. SOLUTION: This image-reading apparatus acquires image data by using an image sensor having a light emitting means and a photo receiving means for receiving light emitted from the light emitting means to obtain image data. The photo receiving means separately acquires light amount data in a plurality of wavelength regions. The image-reading apparatus has a reading control means for controlling the image sensor. The reading control means independently controls a start and an end of each of light receiving operations of the photo receiving means conducted in the plurality of wavelength regions.
