Abstract:
A plurality of images obtained by capturing, dividing over a plurality of times, a printed material in which additional information is embedded are input. Feature information concerning each of the inputted plurality of images is extracted. A poor quality area in the images is evaluated. An overlapping area of the plurality of images is specified based on the feature information. Additional information embedded in the printed material is extracted based on a result of the evaluating and a result of the specifying.
