Abstract: The invention relates to a film scanner comprising at least a first frame store (5) for storing the digitized pixel data of a scanned film frame, and at least a control device (6) for reading the relevant pixel data of a frame section of the stored film frame from the first frame store (5). To generate output frames in an arbitrary format and resolution, which may be used, for example for further processing in real-time multimedia applications, the control device (6) in the film scanner is provided with an arithmetic-logic unit for generating an output frame in a given size, a given aspect ratio and a given number of pixels per output frame line and lines per output frame by computing new pixels. By determining the format, particularly the resolution, for the output frame already during the scanning process, a direct further processing on computer panels or in multimedia applications is made possible. The transfer rate and the capacity required for storing the data are also reduced in this way.
