Abstract: An apparatus for facilitating sequential viewing of streams of images of a common scene. The images are captured by an image sensor system having different viewing configurations generating visually dissimilar views. The electronic circuitry is configured, on transition between a first and a second viewing configurations, to input images captured using the first or second viewing configurations, and to generate a signal, derived from the input images. The signal corresponds to a gradual graphic transition between images captured using the first and the second viewing configurations, thus simulating a continuous viewing of the common scene. The gradual graphic transition includes transition due to 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.
