Solid state image sensor, image scanner, and image scanning program

An image scanner, comprising:

• an illuminating section for irradiating illumination to an original;
• a solid state image sensor including;
• two or more linear arrays of photosites in which a plurality of photosites are closely and one-dimensionally arranged in one direction, the plurality of photosites being for accumulating charge in accordance with light from the illuminated original;
• and transfer parts provided for said two or more linear arrays of photosites respectively, for transferring, array by array, the charge accumulated in each of the photosites of said two or more linear arrays, in which said two or more linear arrays of photosites are closely arranged in a rectangular region in a direction perpendicular to said one direction, the rectangular region being long in said one direction;
• a moving section for relatively moving a captured area and said original in a sub-scan direction corresponding to said perpendicular direction of said solid state image sensor, the captured area being an area on said original corresponding to said rectangular region of said solid state image sensor;
• and
• a control section for scanning a two-dimensional image of said original by controlling at least said solid state image sensor and said moving section, wherein:
• said control section includes a transfer control part for controlling said solid state image sensor to transfer the charge accumulated in each of the photosites in said rectangular region;
• and
• said transfer control part simultaneously controls said transfer parts to simultaneously transfer said charge from each of said linear arrays of photosites.

A image scanning program for scanning a two-dimensional image of an original by controlling at least a solid state image sensor and a moving section of an image scanner, the image scanner comprising:

• an illuminating section for irradiating illumination to an original;
• a solid state image sensor including;
• two or more linear arrays of photosites in which a plurality of photosites are closely and one-dimensionally arranged in one direction, the plurality of photosites being for accumulating charge in accordance with light from the illuminated original;
• and transfer parts provided for said two or more linear arrays of photosites respectively, for transferring, array by array, the charge accumulated in each of the photosites of said two or more linear arrays, in which said two or more linear arrays of photosites are closely arranged in a rectangular region in a direction perpendicular to said one direction, the rectangular region being long in said one direction;
• and
• a moving section for relatively moving a captured area and said original in a sub-scan direction corresponding to said perpendicular direction of said solid state image sensor, the captured area being an area on said original corresponding to said rectangular region of said solid state image sensor, said image scanning program comprising the step of
• controlling said solid state image sensor to transfer the charge accumulated in each of the photosites in said rectangular region, wherein
• in the controlling step, said transfer parts are simultaneously controlled to transfer said charge from each of said linear arrays of photosites.
