<p>A system includes circuitry that receives a user input, which may be a gesture. The system smoothes a trajectory of the user input to generate a smoothed trajectory, when the user input is a first gesture that traces the trajectory over an image. The system also applies an effect to the image to cause a target image to be enlarged and displayed on a display screen and to cause the target image to move based on the smoothed trajectory. The target image is a subset of the image.</p> |
