Abstract: A system creates an electronic file corresponding to a printed artifact by launching a video capture module that causes a mobile electronic device to capture a video of a scene that includes the printed artifact. The system analyzes image frames in the video in real time as the video is captured to identify a suitable instance. In one example, the suitable instance is a frame or sequence of frames that contain an image of a page or side of the printed artifact and that do not exhibit a page-turn event. In response to identification of the suitable instance, the system will automatically cause a photo capture module of the device to capture a still image of the printed artifact. The still image has a resolution that is higher than that of the image frames in the video. The system will save the captured still images to a computer-readable file.

Abstract: A mobile electronic device application uses various hardware parameters for operation. The application leverages calibration data from other users to determine what the parameters should be for the particular device model on which the application is installed. The application queries a cloud-based data store by sending the model and a hardware-variable parameter to the data store. If a value for the parameter is available in the data store, the application will receive it from the data store and use it in operation. If the value is not available, the application will prompt the user to calibrate the application. The application will use the calibration results to identify a setting, and it will send the setting to the data store for use by other instances in which the application is installed on the same model device.

Abstract: A system creates an electronic file corresponding to a printed artifact by launching a video capture module that causes an imaging sensor of a mobile electronic device to capture a video of a scene that includes the printed artifact. The system analyzes image frames in the video in real time as the video is captured to identify a suitable instance. The suitable instance is a frame or sequence of frames that contains at least a portion of the printed artifact and that also satisfies one or more image quality criteria or other criteria. Upon identification of each suitable instance, the system will automatically cause a photo capture module of the device to capture a still image of the printed artifact. The still image has a resolution that is higher than that of the image frames in the video. The system will save the captured still images to a computer-readable file.
