PROBLEM TO BE SOLVED: To make joints of images unremarkable in the case that a plurality of images whose exposure differs and whose parts are picked up overappingly are connected to obtain one panorama image. SOLUTION: A cross reference point extract section 1 detects cross reference points of two input images a, b, a parameter estimate section 2 estimates a parameter to made coordinate transformation of the extracted cross reference points and a gradation correction coefficient decision section 3 obtains a coefficient to weight the images a, b based on the estimated parameter. Gradation correction control sections 4, 5 correct duplicate parts of at least either of the images a, b. An image synthesis conversion section 6 weights at least either of the images a, b and adds the result to the original image and synthesizes the sum image and the other image based on the parameter. |
