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.

In filter processing, a filter coefficient for which a weighting has been set is used for each of a plurality of pixels in a sub-scanning direction in a predetermined section of a main-scanning direction and the weighting for each of the plurality of pixels is determined such that a center of gravity of the weighting shifts in the main-scanning direction gradually from one end of the predetermined section to the other end.

This optical scanning method yields a high quality image regardless of the size of the scanning area. An emission end of an optical fiber is displaced two-dimensionally to scan light emitted from the optical fiber, the emission end being displaced by an optical scanning actuator that includes a first driver and a second driver for driving the emission end in different directions. A non-circular scanning area is scanned by controlling, with a driver controller, a first drive signal supplied to the first driver and a second drive signal supplied to the second driver so as to rotate a scanning pattern of the light, while causing the scanning pattern to reciprocate repeatedly in a nearly parallel manner, and to change a length of the scanning pattern in accordance with a rotation angle of the scanning pattern.
