Abstract

A device for converting a color image into an electrical signal comprises a station for presentation of the image in an image plane, a scanning device (7) with at least one light sensitive element arranged to create an electrical signal which represents the brightness of the image in the scanned region and means for moving the light sensitive element over the image plane in a pattern consisting of a number of scan lines covering the image plane, and means for placing exchangeable color filters (34) in front of the light sensitive element in order to obtain a color separation of the image. Each of the color filters is smaller than the image plane and is of a size adapted to generally cover one or a few of said scan lines. A single color filter may be held in front of the light sensitive element (Fig. 2), for manual replacement for successive scans, or a plate (32) may be provided carrying a plurality of filters, the plate being movable with respect to the light sensitive element.
