A method and a device to provide a full representation of an object having a wide dynamic intensive range and maintain a good sensitivity for signal levels throughout the whole intensive range is disclosed. The wide intensive range is divided into a predetermined number of intensive intervals inside the wide intensive range. The intensive intervals are provided at the side of each other or are partly overlapping. The same number of interval representations of the object are provided as the predetermined number of intervals. Each interval representation is adapted to one individual of the intervals. The sizes, acquisition parameters and/or calibration parameters of the interval representations are adapted to each other. The interval representations are combined such that their respective intervals are provided in the same full representation.
