Abstract
An image recognition device includes a detection unit which is configured to detect a first difference between at least a part of the first image information and the reference information, a second difference between at least a part of the second image information and the reference information, and a third difference between at least a part of the third image information and the reference information. A recognition unit is configured to make a first determination whether the first difference is within a predetermined range, and to make a second determination whether the second difference is within the predetermined range. A changing unit is configured to change the predetermined range based on the first and second determinations. The recognition unit is configured to recognize an area corresponding to the reference image in the third image information based on the third difference and the predetermined range which has been changed.
