PROBLEM TO BE SOLVED: To specify an area not included in the difference result for every two input images, when detecting the difference of two input images to be compared.SOLUTION: A screen data acception unit 41 accepts new and old screen data. An exclusion area specification unit 42 specifies an exclusion area, respectively, for every new and old screen data accepted by the screen data acception unit 41. A difference detector 43 detects the difference of the image data included in an area other than the exclusion area specified by the exclusion area specification unit 42, in the new and old screen data. A difference image generation unit 45 generates a difference image indicating the difference result detected by the difference detector 43. |
