ABSTRACT:
An imaging device such as a video camera having a viewfinder for displaying an imaging signal to the photographer which indicates the degree of hand wobble (i.e., movement of the camera by the photographer). A hand wobble display circuit generates this imaging signal for the viewfinder by generating a field-difference or a frame-difference signal of the electronic viewfinder signal and displaying the difference signal on the viewfinder. The magnitude of the difference signal can be used to determine the degree of hand wobble.
