An image scanning apparatus includes a scanning section which scans an object opposite to a linear scanning area along a main scanning direction while moving the scanning area along a subscanning direction intersecting the main scanning direction. The scanning section generates image data on the basis of the result of the scanning. A control unit of the scanning section includes a first image acquiring section that acquires first image data by making the scanning section execute scanning at a first subscanning resolution. The control unit also has a pattern searching section that searches the first image data for the image of the predetermined pattern. A second image acquiring section of the control unit acquires second image data in such a manner that when the image of the predetermined pattern is not detected by the pattern searching section.
