Abstract: Image augmentation effects are provided on a device that includes a display and a camera. A simplified augmented reality effect is applied to a stream of images captured by the camera, to generate a preview stream of images. The preview stream of images is displayed on the display. A second stream of images corresponding to the first stream of images is saved to an initial video file. A full augmented reality effect, corresponding to the simplified augmented reality affect, is then applied to the second stream of images to generate a fully-augmented stream of images, which are saved to a further video file. The further video file can then be played back on the display to show the final, fully augmented reality effect as applied to the stream of images.
