Abstract
In an image reading apparatus capable of converting the resolution of an image read by a color line sensor by using an image read by a monochrome sensor, a technique that realizes proper use of resolution conversion processing in accordance with the type of the image on the reading target is provided. An image reading apparatus includes: a first image reading unit configured to carry out monochrome image reading with a first resolution from a reading target; a second image reading unit configured to carry out color image reading from the reading target, with a second resolution that is lower than the first resolution; a type determining unit configured to determine whether the image on the reading target is of a first image type for which luminance resolution is given priority, or of a second image type for which color reproducibility is given priority; and a processing executing unit configured to, when it is determined by the type determining unit that the image is of the first image type, execute resolution conversion processing to raise the resolution of image data read by the second image reading unit by using image data read by the first image reading unit.
