Image combining device, image combining method and program to implement image combining method

摘要

An image combining device may include an image reading unit that reads an image of a first and second partial area which have a portion overlapping; a template area setting section that sets apart an area of a predetermined shape as a comparison area from the overlapping area; a calculation area setting section that selects areas of the shape corresponding to the shape of the comparison area; a correlation coefficient calculating section that calculates a correlation coefficient between each of the image data values of the multiple areas; an area identifying section that identifies, from the multiple areas, the area in which the calculation result satisfies a predetermined condition; and a combining section that combines the images of the first and second partial areas in the positional relationship in which the area identified by the area identifying section and the comparison area overlap with each other.
