Abstract
A scanner includes a generator that synthesizes output of a first sensor group and output of a second sensor group where the image data overlaps in part, and generates image data; and a controller that controls the second sensor group to synthesize and output the output of n photoelectric conversion elements at positions based on the relative positions of the first sensor group and second sensor group.
Claims9
A scanner comprising:
- a first sensor group of photoelectric conversion elements at a resolution A;
- a second sensor group of photoelectric conversion elements at a resolution A;
- a generator that synthesizes first image data output by the first sensor group and second image data output by the second sensor group where the image data overlaps in part, and generates image data;
- and
- a controller that, when scanning a document at a resolution A/n (where n is an integer of 2 or more), selects positions to synthesize the output of n photoelectric conversion elements based on the relative positions of the first sensor group and second sensor group,
- the second sensor group synthesizing and outputting the output of n photoelectric conversion elements at the selected positions.
