1. A method of creating an electronic file corresponding to a printed artifact, the method comprising: by a video capture module of a mobile electronic device, capturing a video of a scene that includes a printed artifact, wherein the video comprises a series of image frames, and at least some of the frames include an image of a portion of the printed artifact and a page-turn event; by a processor, analyzing a plurality of the image frames in the series in real time as the video is captured to identify a suitable instance, wherein identifying the suitable instance comprises identifying a subset of one or more image frames in the series that include an image of a page or side of the printed artifact and that do not exhibit a page turn event by: determining a stacked blob that is stacked over a number of successive frames, wherein the stacked blob corresponds to a motion in the video, measuring a size of the stacked blob, and determining that a frame exhibits a page turn event if the size of the stacked blob is greater than a threshold; in response to identification of the suitable instance, without requiring user input, automatically causing a photo capture module to capture a still image of the printed artifact so that the still image has a resolution that is higher than a resolution of the image frames from the video; and saving the still image to a computer-readable file.
