<p><P>PROBLEM TO BE SOLVED: To precisely perform position adjustment of a plurality of original images including a common part with each other, and to accurately extract the image of the common part from the plurality of original images. <P>SOLUTION: The image processor includes: a feature point extraction part 11 for extracting the feature point (first feature point) of first original image data and feature point (second feature point) of second original image data; a feature amount calculation part 12 for calculating the feature amount (first feature amount) of the first feature point and the feature amount (second feature amount) of the second feature point; a collation processing part 13 for comparing the first and second feature amounts and extracting the first and second feature points whose feature amounts match; a coordinate transformation part 14 for transforming the coordinate system of the second original image data to the coordinate system of the first original image data on the basis of the coordinates of the extracted first and second feature points; and a logical AND calculation part 15 for obtaining the logical AND of the first original image data and the coordinate-transformed second original image data and extracting the image data of a common format included in the first and second original image data. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
