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.

Abstract: Substantially removing shadows in video images obtained from a camera viewing a scene, at variable pointing angles and magnification, by digital processing of a sequence of frames in the video signal, the processing including—(a) creating and maintaining a model image of the scene, by accumulating image data from a plurality of video frames; (b) in the model image, detecting and defining model shadow zones; (c) calculating correction factors for the model shadow zones; (d) for each frame of the video signal—defining, in the image carried by the signal, shadow zones that correspond to respective model shadow zones; and (e) correcting video signal values in shadow zones accordingly.
