  • Mô tả: To provide, in addition to a preferably black/white scanning, also a coloured reproduction of coloured originals (14), a slider (22) is arranged in the beam path (21) of the light reflected from the original (14). The slider (22) has four fields arranged behind one another. The first one is an opening (23) which allows the light to reach an optoelectronic transducer (20) via optics (19). In this position of the slider (22), the black/white scanning occurs. The remaining three fields are provided with coloured filter discs (24R, 24G, 24B). One colour scan consists of a cycle of three scans of the original (14) which occurs in each case with interposition of a different filter disc (24R, 24G, 24B) at reduced scanning rate. The three colour separations obtained by this means are stored for further processing in frame buffers.
