ABSTRACT:
An electronic imaging camera is provided with a substantially expanded dynamic exposure range by implementing two succeeding exposure intervals under conditions where the exposure defining parameters are substantially different and thereafter selectively choosing between the electronic information signals sensed during the two succeeding exposure intervals to provide an output signal from which a visible image of the subject may be reconstructed thereafter.
