ABSTRACT:
An image reading apparatus includes: (i) a capturing device for capturing an original image of a source document; (ii) a moving device for moving one of the capturing device and the source document relative to the other; (iii) a first region processor for causing the moving device to position the capturing device in a first capturing position, so as to obtain a first pixel-related data relating to pixels present in a first region of the source document; (iv) a background-color-basis correcting-value determiner for determining a background-color-basis correcting value, based on the first pixel-related data; and (v) a second region processor for causing the moving device to position the capturing device in a second capturing position, so as to obtain a second pixel-related data relating to pixels present in a second region of the source document. The second region processor is configured to correct the second pixel-related data, based on the background-color-basis correcting value, for reducing influence on the second pixel-related data by a background color of the source document.
