Abstract
A method of identifying the activity of a camera used for capturing an image or video, such activity not being related to the activity of subjects of the scene being captured includes determining a steadiness signal related to movement of the camera while capturing an image or video, wherein the steadiness signal identifies the motion of the camera in at least two dimensions as a function of time; and using a processor for determining a camera activity classification for the camera based on an analysis of the steadiness signal, wherein the camera activity classification includes categories of the camera being stationary, the camera being located in a moving vehicle, the camera being held by hand, or the camera being held by a jogging or walking user.
