ABSTRACT:
A multiple-field sensor for a scanner suitable for scanning a document. The scanner includes a multiple-field sensor, an average accumulator, and a block of memory. The multiple-field sensor has a plurality of sensing lines for each color channel. Each sensing line picks up a portion of image signal from the document during scanning. The sensing lines scan the same portion of the document to produce corresponding image signals. The average accumulator averages the image signals obtained from the sensing lines of the same color channel to produce an average image signal. The block of memory is used as a storage area for image signals in general and the average image signal in particular.
