ABSTRACT:
The invention provides an arrangement and a method for generating electrical image signals from an image original. The arrangement is, for example, a film scanner which illuminates or transilluminates a photographic image on a film using an illumination device. Optical signals generated hereby are converted into electrical signals by a CCD sensor subdivided into segments. The segments of the CCD sensor are connected via mutually independent readout channels to a signal processing stage, where the electrical signals of the readout channels are combined with one another in such a way that these represent a total image. Furthermore, an adjustment unit is provided which adjusts the transfer functions of the different segments of the sensor with respect to one another in such a way that visible image disturbances are avoided.
