Abstract
An image reading apparatus includes a first sensor that reads a first area of an image, a second sensor that reads a second area, and a processing circuit that generates a merge image by performing a merge process on first image data acquired by reading by the first sensor and second image data acquired by reading by the second sensor. The processing circuit calculates a correction value having a tendency of approaching zero as being away from an overlap area between the first area and the second area based on a reading result acquired by reading the overlap area by the first sensor and a reading result acquired by reading by the second sensor, and generates the merge image by performing an offset process using the correction value.
