Abstract
In a method or system for scanning a source image, the source image is scanned with a sensor that comprises multiple line arrays designed to detect a specific color such that a color separation of the source image to be scanned is generated by each line array. The color separations represent the source image in the form of pixels. The pixels of the different separations of the source image are at least partially offset relative to one another. The pixels of the color separations are separately filtered with multiple FIR sub-filters. The filtered pixels of the source image of the multiple color separations are summed into pixels of a target image.

A method for scanning a source image, comprising the steps of:
- scanning the source image with a sensor that comprises multiple line arrays respectively designed to detect a specific color such that a color separation of a source image to be scanned is generated by each line array, said color separations representing the source image in the form of pixels, the pixels of the different color separations of the source image being at least partially offset relative to one another;
- and
- separately filtering the pixels of the color separations with multiple FIR sub-filters, and summing the filtered pixels of the source image of the different color separations into pixels of a target image.
A device for scanning of a source image, comprising:
- a sensor that comprises multiple line arrays respectively designed to detect a specific color, such that a color separation of the source image to be scanned is generated by each line array, said color separations representing the source image in the form of pixels, the pixels of the different color separations of the source image being at least offset relative to one another;
- and
- a control unit designed such that a FIR sub-filter is respectively applied to the color separations in order to map the pixels of the different color separations to a single target image.
