<P>PROBLEM TO BE SOLVED: To correct pixel values of each image to make the seams unnoticeable when two or more images are combined and to prevent overexposure or underexposure for each image. <P>SOLUTION: An image input unit 101 inputs a plurality of partial images acquired by a detector, etc. An offset value acquisition unit 102 calculates for each partial image a difference between pixel values of overlapping areas of respective partial images as an offset value. A pixel value acquisition unit 103 acquires minimum and maximum pixel values for each partial image as values indicating a pixel value range. A correction value acquisition unit 104 calculates a correction value of the plurality of partial images. A correction unit 105 corrects the gradation of the plurality of pixel values. A combining unit 106 combines the plurality of partial images to generate a combined image. <P>COPYRIGHT: (C)2012,JPO&INPIT |
