1. Apparatus for facilitating sequential viewing of first and second streams of images of a common scene, the streams of images being captured by first and second image sensors, respectively, the first and second image sensors capturing the first and second streams of images from different viewing directions so as to generate visually dissimilar views of the common scene, the apparatus comprising electronic circuitry configured: (a) to input at least one image from at least one of said first and second streams of images; and (b) to generate a signal, derived at least in part from said at least one image, said signal corresponding to a gradual graphic transition between the viewing direction of the first image sensor and the viewing direction of the second image sensor, said gradual graphic transition simulating a continuous view of the common scene from intermediate viewing directions between the first viewing direction and the second viewing direction.
