Abstract: A method for processing an image includes receiving an input image having distortion, receiving position information input by a user on the received input image, generating a first image by correcting the input image having distortion, and translating a position on the input image having distortion indicated by the received position information into a position on the generated first image. The method further includes setting, on the generated first image, a first mask area having a predetermined shape and including the position on the generated first image translated from the position on the input image having distortion, and performing mask processing on the set first mask area on the generated first image.
