1. A method of image processing, the method comprising: receiving images including a non-stationary object, each image taken at a different time; detecting the non-stationary object in the images; displaying a first image including the non-stationary object among the images; detecting a selection of a frame region including a portion of the non-stationary object in the first image and displaying a graphic indicator of the frame region on the display; selecting a second image having a lowest similarity among the images with image data of the frame region; replacing the image data of the frame region of the first image with image data of the frame region of the second image such that the portion of the non-stationary object is removed from the first image and another portion of the non-stationary object is maintained in the first image; and displaying the first image with the replaced image data on a display, wherein the second image having the lowest similarity indicates an image that is absent the portion of the non-stationary object within the frame region of each of the images, and wherein the graphic indicator is defined by a radius centered on a point of the non-stationary object indicated by a user input, the radius further modifiable in response to a user gesture.
