1. Apparatus for facilitating sequential viewing of streams of images of a common scene, the images being captured by an image sensor system comprising at least one image sensor, said image sensor system having at least two different viewing configurations generating visually dissimilar views of the common scene, the apparatus comprising electronic circuitry configured: (a) on transition between a first viewing configuration and a second viewing configuration, to input at least one image captured using at least one of said first and second viewing configurations; 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 images captured using said first viewing configuration and images captured using said second viewing configuration, said gradual graphic transition simulating a continuous view of the common scene, and said gradual graphic transition includes at least one transition selected from the group of transitions consisting of a change of viewing direction, a change of aspect ratio, a change of sensor technology, a change of spectral sensitivity, a change of sensor sensitivity, a change of spatial resolution, a change of sensor location, a change of binning level, a change of displayed region of interest, a change of displayed resolution and a change of a image sharpness.
