    • Certain embodiments provide an image reading apparatus including: a monochrome CCD sensor including a first photo-diode array; plural color CCD sensors each including a second photodiode array; an AD converter configured to apply analog-to-digital conversion to each of analog outputs from the second photodiode array and the first photodiode array; a delay processing unit configured to delay at least one of color image data of plural colors from the AD converter and interpolate, with delayed any one or more of the color image data, a blank of image data that is to be read on a line in a sub-scanning direction; and an inter-line correction unit configured to correct, by the intervals and a set reduction magnification, a positional deviation in the sub-scanning direction between the monochrome image data and the color image data, respective timings of which are aligned on the line by the delay processing unit.
